How is the peephole in the door. door peepholes

The peephole is a part of the front door, without which we have not imagined life for a long time. This is a kind of pass to our home: we see the guest and decide whether we want to let him inside or not. Modern models door peephole and do allow you to monitor what is happening on the landing remotely, from the office or while on vacation. The market provides a huge selection, so you can find something to your liking, requests and wallet.

How is the door peephole

Don't forget that peephole is an optical device. Therefore, it cannot function without two main components: an eyepiece and a lens. The body of the peephole can be made of metal or plastic. When choosing quality, give preference to metal.

The fisheye is also an integral part of the classic door peephole. It is designed to enlarge the image, so people appear much larger through the peephole. Lenses are also placed in the case, from two to fifteen pieces. The number of lenses depends on the length of the device and is responsible for the light transmission.

Lenses, in turn, can also be of two types: glass and plastic. Plastic is relatively cheaper than glass, but quickly fails, loses its crystal transparency. You will find the first signs of aging in 2-3 years. Therefore, it is better to purchase a peephole with glass lenses. Additionally, some door eyes are equipped with armor-piercing glass lenses.

The size of the device varies according to the thickness door leaf. A metal leaf is thinner than a wooden one, but layering is practiced in modern doors, so a steel door may be thicker than an old wooden one. There are door eyes of the following size:

30-55 mm. This is the thickness of a standard front door;
55-100 mm. Doors with sheathing or decorative elements;
Over 100 mm. Armored doors, which are more often used at protected facilities, in warehouses for especially valuable goods.

The viewing angle of the peephole ranges from 150 to 200 degrees. It is considered optimal to have a 180-degree view: this way you will see both the face and a significant part of the landing.

When choosing a door peephole, pay special attention to the class of the door itself.

Door peephole: types

Standard. The eyepiece and lens form a single line, and are located opposite each other. The simplest and most affordable version of the peephole. It is customary to install simple models doors. But even taking into account the availability of this model, we recommend choosing eyes with glass lenses and a metal body - they will last longer.

Periscopic. It is a more complex structure. There are two eyepieces on the inside, and a lens on the outside. The image is transmitted to the second eyepiece using mirror lenses. Why is such a design needed? For convenient use by residents of different heights. If there is a child in the family and you are afraid to leave him alone because he will not be able to look through the peephole, install a periscope model for his convenience.

Secret. The outer part of such a peephole is located outside the door leaf, usually on top or at the ends. Outside, no one will guess that a resident of the house can watch him.

Panoramic. large eyepiece, large diameter cases and the ability to look "in both eyes" are overshadowed by difficulties in installation. Transmitting lenses are located inside the structure. But the viewing angle is extremely large - you see the entire landing.

Electronic peephole with video camera. Most modern look door peephole. It has the function of video shooting, recording and even broadcasting. Therefore, you can easily find out what happened on the site in your absence. We will consider this type of eye in more detail at the end of the article.

Installing a peephole in a metal door

The principle of installing a door peephole is identical for doors made of any material, be it steel, wood or veneer. When working with metal, there is only one fundamental difference - the thickness of the door and the density of the material. Therefore, you will have to spend more effort and choose a peephole model bigger size. Moreover, metal doors are often complemented inner lining from MDF and decorative elements, which somewhat complicates the task.

Installation steps for the viewing device in metal door:

Using chalk or pencil, mark the location of the future eye. Consider the height of all family members and choose the average.
To avoid deformation interior decoration door or its coverings, stick a film or tape on the drilling site.
Measure the diameter of the eyelet body. If the part has internal thread- use a drill wider than the result obtained by half a millimeter.
You need to drill from the inside, directing the drill towards the outside of the door.
Do not drill through the door. Get to the outer layer exterior finish and stop. Then drill with outside. This little trick will help to avoid the formation of nicks, chips and bumps.
A lens is installed from the outside. From the inside, respectively, the eyepiece.
Connect both parts of the eye with screwing movements.

Electronic door peephole: types, advantages, installation

Video eye is complex view device that makes life safer. Unlike classic analogues, the electronic peephole is easy to use and has an impressive set of functions.

Kinds

Today it is customary to distinguish three types of electronic eyes:

Wireless with color recording function. Installed like a normal peephole. In terms of image quality, it is inferior to monochrome and costs more. But it has the function of video recording in color.
Monochrome, infrared. Easy installation, IR illumination, convenient operation. Monochrome peephole will be a worthy alternative to the usual.
Electronic black-and-white peephole complete with a matrix camera. Difficult installation, image distortion, small monitor. Of the benefits - an affordable price.

Advantages

Despite the complexity of design and installation, as well as high price, video peephole is gaining popularity. What is the reason? Consider the main advantages of an electronic analogue:

Displaying an image on a monitor. This is convenient for those who do not like to squint and close one eye. From a comfortable distance you can see the panorama of the staircase.
Night vision function. IR illumination is convenient at night, when an ordinary peephole simply cannot cope with its main task.
Recording function. Suitable for those who are especially reverent about security. You may be on the other side of the world, but know exactly what is happening in your entrance and who is coming to the front door of the apartment. How it works? The peephole is connected to a computer or other device for the purpose of storing data. Also in each model with a recording function there is a slot for a microSD card.
Built-in motion sensors. An additional bonus in the piggy bank of the security system. Even in the dark, you will know that there is someone next to the door. The system is adaptive both for residential buildings and for office space and warehouses. Is an great addition the main room alarm system.
You don't need to get a license. Classic video surveillance systems are subject to mandatory licensing in some cases. The use of an electronic eye with a video recording function does not require a license. This is true for any purpose from private to commercial.

Installation of an electronic peephole in an iron door

Different types of electronic eyes are installed according to the same principle. However, the installation of each of them is worth observing the individual subtleties, which we will discuss below.

Set the exact thickness of the front door. In most cases, adapter rings are included in the video peephole kit, but even they are designed for a certain size of the door leaf.

The size of the hole in the door directly depends on the diameter of the case. In most cases, a standard connector from an old peephole is fine. In some cases, you will have to increase the diameter. You can do this with a perforator. To do this, select a nozzle desired diameter and drill in turn on each side, without going through. This will help to avoid external defects in the door leaf.

Next, install the camera in the hole and fix the monitor. Usually, the kit includes special bolts that are easily screwed in with a screwdriver. If the peephole is wireless, the body mount will become final stage installation.

Some models are mounted on the door itself or next to the hole from the old peephole. You need to carefully read the instructions, and it is better to contact a specialist.

There are also models that work from the network. Additional manipulations are performed with them in order to connect and mask the wire. Such devices are not recommended to be installed independently.

Connecting a video eye: video

The choice of complexity, price and type of peephole depends on such factors as: door class, financial capabilities and the need to increase the level of security. Consider the ratio of all these parameters during selection and installation. Guardian metal doors correspond in their technical specifications any type of eye. In order to increase security, you can order a door with an additional armored leaf or decorative elements to your taste.

Think installing a peephole is difficult? The accumulated experience allows me to assert that even an inexperienced master can do this work. I will tell you how to choose quality equipment and I will give instructions with illustrations that will allow even those who have never put a peephole in the door to cope with the work.

Main element conventional peepholes - a wide-angle fisheye lens that provides a high-quality view of space. Electronic versions use a camera.

First, let's look at what types of eyes are:

Illustration	Description
	standard peephole door. This option is simple and consists of two parts - outer and inner, which are twisted together. A lid may be present in the design to close the hole from light penetration.
	Panoramic peephole. His distinguishing feature- a lens divided into two lenses. This design allows more light to pass through. To see the image, it is not necessary to stand close, you can be located on the side of the structure.
	Double door system. It can be either standard or panoramic. The design consists of two parts, during installation, special accuracy must be observed so that the elements match.
	Bulletproof option. Used on bulletproof door panels to ensure structural integrity. According to the installation method, it is no different from the usual version.
	Peephole-periscope. This option is ideal for those with small children. You can watch both in the normal position and at the bottom, which is very convenient if you need to exclude the option of opening the door strangers. The system is quite difficult to install, so most often the work is done by specialists.
	Video-eye electronic type . Previously, video options required signal settings in order to transmit it to a monitor or TV. Modern technologies have made it possible to make a compact and simple option that anyone can easily install.

If you have decided on the type, it is worth understanding several criteria that are taken into account when choosing:

Viewing angle. The larger it is, the better you can see the space in front of the entrance. For cheap options, the angle is 120 degrees, for more advanced ones - 180 degrees. The highest quality modifications have a view of over 200 degrees, this allows you to eliminate distortion along the edges of the image;

Door leaf thickness. There are three product options:

up to 60 mm;
up to 100 mm;
over 100 mm.

Any version of the eye is adjustable by 20-30 mm due to the thread. Some models come with different bushings so you can match optimal solution under your door;

Eye diameter. This indicator determines the size of the hole to be drilled. If in new designs you can choose any option, then when replacing old elements, it is easiest to choose products of the same size. Most often, the diameter of the inner part is 20 mm;
Production material. Optics can be plastic or glass, the price of the first option is much lower, but the second is much stronger and more durable. The case can be made of plastic or metal, the second option is preferable, although it costs more.

I will talk about two options for carrying out work: installing a regular peephole and a variant with video surveillance.

Mounting a standard peephole

We will figure out how to install a peephole in a metal door.

Illustration	Stage description
	Measurements are being made. We are primarily interested in the thickness of the canvas, other dimensions are not so important. Knowing the thickness, you can choose a suitable peephole, and not buy it at random.
	The instrument is being prepared. To do the work yourself, you need the following: Screwdriver with a drill for metal with a diameter of 5 mm; Feather drill with a diameter of 20 mm; Core drill for metal with a diameter of 20 mm; Roulette construction. If the diameter of your eye is larger, then the spade and core drill is selected in accordance with the parameters of the product.
	The center of the door leaf is marked. The eye is usually located in the middle, so use a tape measure and a pencil to mark the middle.
	The height of the peephole is noted. The standard option is 150 cm from the floor level, but you can raise or lower the peephole so that its use is as comfortable as possible.
	Drilling in progress. First of all, a through hole with a diameter of 5 mm must be drilled in a metal door. It is very important to use a drill of sufficient length so that it comes out with reverse side doors. When drilling, pay special attention to the horizontal position of the screwdriver. If the hole turns out to be skewed, then the eye will become crooked.
	Drilling a hole from the outside. A crown for metal is inserted into a screwdriver or an electric drill, with the help of which the hole expands to the diameter we need. It is important to work carefully so as not to damage the door leaf and not bend it.
	Drilled lining from the inside. For work, a pen drill is used, the main thing is to hold the screwdriver evenly so as not to go to the side.
	The hole is cleared of debris and checked. Just look through it, if there are no distortions, then everything is done as it should.
	The peephole is fixed. To do this, it should be held from the outside and screwed in from the inside. If there is a key in the kit, then you can additionally clamp the knot from the inside.
	Checking system operation. Close the door and look through the peephole. This completes the installation.

Installation of an electronic peephole

Consider how the camera is installed:

Illustration	Stage description
	This is what the camera kit looks like. It includes: Monitor with control buttons; Accumulator battery; Memory card; Camera; Mounting platform. All you need is a screwdriver to work.
	The battery is inserted. If your system is powered by batteries, then batteries are installed.
	Inserting a memory card. A special slot is provided for it, you will not confuse anything in any case.
	Remove the protective film between the power contacts. Usually there is a tab on the outside that you need to pull and thereby remove the protection from the contacts.
	The sleeve is twisted from the camera. It will hold the element from the inside, so it should be removed in advance.
	The sleeve is inserted into the mounting platform of the camera. On this preparatory work completed.
	A platform with a sleeve is placed on the door leaf. For clarity, the work is shown on a transparent module that imitates doors 70 mm thick. Naturally, before changing the system, you need to remove the old peephole. If you have new door, then all the features of drilling holes are described above, the technology is also suitable for this case.

The front door is an important and integral element of any home. It fences off the outside world from the private space of an apartment or house. The stronger and thicker it is, the more reliable the protection. But there are cases when it is necessary to find out what is happening behind the door without opening it. It is for such situations that a door video peephole is needed, which will help assess the situation and prevent uninvited guests from appearing on the threshold.

What is a peephole for?

Door peepholes are important functional elements of any door, allowing you to unilaterally inspect the space outside the boundaries of the apartment (on the landing), without requiring the doors to be opened. In addition, such an attribute will help prevent uninvited guests from visiting the house.

Important! Modern industry offers quite a variety of door peephole options, some of which are equipped with video cameras and other security and control systems.

Design features

Regardless of the type of peephole, its design has a standard set of elements:

A lens that enlarges the image and provides an external view;
External rail holding the lens;
Clamps that firmly hold the lens;
Frame;
Inner nut;
A lens or eyepiece directed into the room;
damper.

The number of lenses in different models and types can vary from 2 to 15 pieces.

Varieties

Door eyes have a large number of varieties, each of which has a special functionality and additional features. Most often, the following types of equipment are installed on the door:

A standard classic peephole installed on a metal or wooden door for more than a dozen years. This device, although it makes it possible to see what is happening behind the door, does not provide sufficient visibility. You can only see what is directly in front of him.
Panoramic peephole. The lens of such an eye has a design divided into two lenses. This allows the lens to take on a large light flux, making the image panoramic. At the same time, it is not necessary to strictly stand close to the door or to the peephole. Everything is visible from different viewing angles.
Peephole door concealed type. Most often, it is disguised as nails included in the door trim, or others. decorative elements. Such a device can be equipped with a camera, masked from the outside, if the doors are a continuous sheet.
Bulletproof peephole. The name speaks for itself. This element is most often equipped with armored doors that provide maximum protection against unauthorized entry.
Eyelets for double doors. Structurally, such an element consists of two parts and allows you to inspect the external space without opening them.
Periscope. Its peculiarity lies in the fact that the viewing lens and the eyepiece itself are located at different levels.

Attention! This option is especially relevant if the family has small children. You can position the lens at a level convenient for the growth of the child.

Video-eye

In the production of door eyes, modern Hi-tech, the use of which allows you to create practical and functional varieties, among which the video peephole is especially popular.

Its design necessarily includes a microscopic video camera, which is installed at one end of the door element. It transmits the image to a special monitor, and can show what is happening both in real time and in recording.

Depending on the type of device, information from the camera can be transmitted to the reader either via wired lines (cable), or via a radio channel, or via a WI-FI signal. By installing a video peephole on the door, you can be as calm as possible for your safety.

Electronic door peephole

This design also represents an experience in combining electronics and safety features. Door peepholes of electronic type are installed instead of the usual standard peephole. The structure of the external structure includes infrared illumination and light and bell sensors. On the inside The door is equipped with an electronic part of the structure, mounted on a metal plate. On this element there is a screen that opens an overview of the stairwell.

Attention! Unlike a video peephole, it is quite easy to install such a design on your own, directly in place of a standard peephole. There is no need to install wires and set up a signal, and the unit itself runs on standard AA batteries.

Selection and installation rules

Various varieties and price parameters complicate the process of choosing a peephole. To buy high-quality and suitable equipment, you should pay attention to the following parameters:

Viewing angle. The peephole should be chosen according to this criterion, depending on the space near the door. But modern optical devices used in the eyes usually solve this problem at a normal level, providing an optimal viewing angle. In addition, lenses for viewing should clearly show the face of the visitor.
Important! Almost all modern eyes provide a viewing angle of 180 degrees. But there are instances with a large parameter, reaching up to 200 degrees.
door thickness. It can be of a standard type, elongated and exceeding 10 cm. Moreover, the body usually provides for adjusting its length for each type of product.
Light sensitivity. This parameter determines the ability of a clear image transmission in low or dim lighting on the site.
Product width and diameter. If the peephole is already installed immediately on the door, then this parameter is not significant, it is important to know it if replacement is necessary;
The material from which the body of the peephole is made. In most cases, the design is made of metal or plastic. metal element more durable, practical and durable, and plastic has a lower cost, but a shorter service life;
The material from which the lenses are made. It can be plastic, glass, or optics used in the manufacture of eyeglasses. As a rule, the most expensive options are completed with optical lenses, cheaper ones - with plastic ones.

Usually the choice is based on the size of the budget and preferences of the buyer, as well as the required functionality of the device.

Latch on the door peephole

gate valve - important element included with most peepholes. It helps to increase passive safety and at the same time performs an aesthetic function by preventing light from entering from outside. Sometimes, instead of a latch, the manufacturer performs mirror-type deposition on the objective lens. It performs the function of a shutter, but may degrade the quality of the view.

Installation Features

Installing or replacing a peephole does not require special skills or experience, this can be done with a drill and masking tape needed to drill a hole.

If the door peephole is not to be replaced, then before buying a new mechanism, remove the old one, accurately measuring its external parameters. If the door has continuous construction and it was decided to install the peephole for the first time, then a hole of the required diameter should be drilled. To do this, in place of the future element for review, a label is made, on which is attached masking tape. After that, a hole is drilled on both sides of the door. From the outside, a tip is installed on which the lens is located. On the inside, a recorder or lens is tightly fixed, which, if necessary, is twisted.

Embed panoramic peephole and other types

If you do not know how to assemble a door peephole, then this review is for you. In it, we will analyze the main types of products and their features.

You will also learn how to properly install standard and more modern solutions. To carry out all the work quickly and efficiently, you need to follow a few simple recommendations from the relevant section.

Types of products and their features

If in the eighties it was possible to find 1-2 product options on sale, then today the choice is much wider. Therefore, first you should decide on the type of construction that best suits you, and only then figure out how the installation is done.

Types of eyes

You can choose from the following options:

Standard products. The door peephole device of this type is known to everyone: a lens on one side and an eyepiece on the other. The simplest solution, which has a small viewing angle: if someone stands on the side of the wall, then you will not see him. As for the advantages, the most important of them is the low price, this is the most budget modification of the eyes;

Eyes with mirror finish. This option has exactly the same design as the classic one, but has one important advantage. The outer part of the lens is made in the form of a mirror, and the one who is outside does not see the light from the peephole and cannot determine whether someone is looking from behind the door or not. This is a good option for dark porches where the light from the peephole is visible;

Bulletproof products. In appearance they do not differ from ordinary ones, but in terms of reliability they are ten times stronger than them, since they are made of bulletproof materials;

Panoramic door eyes. Provide full review space in front of the front door. You will see both the platform and the walls on both sides of the door. Good decision who do not want to install video equipment. Eyes most often have an increased diameter, which creates certain difficulties during installation, this should also not be forgotten when choosing;

Double door systems. This option is necessary if you have two doors at the entrance. The design consists of two parts that need to be installed correctly so that you can see what is happening outside without tearing off any door. If you need just such an option, then I recommend entrusting its installation to specialists - it is not easy to perfectly combine the two parts of the system;

Eyes of periscope type. As the name implies, the design of the product resembles a periscope. The eyepiece for viewing what is happening behind the door is shifted from the lens to the right, left or down. Such a system is set up quite simply, and its an additional plus it can be considered that from the outside a person will not be able to determine whether someone is looking through the peephole or not;

Digital systems. A convenient modern solution consisting of a miniature camera and a display that is installed from the inside and transmits an image of what is happening outside the door. You do not need to look into the eyepiece - everything will be visible anyway, and you don’t even have to turn on the light. The device runs on batteries, which is also convenient, because you do not need to run wires;

Video system. An even more modern and progressive solution that allows you to transfer an image from a miniature camera to a smartphone or computer monitor. That is, you can see who is behind the door without even getting up from the couch. Another advantage is the ability to connect multiple devices so that all family members can see who is ringing your doorbell;

Video eyes with motion sensor. This option is even more modern - it not only transmits the image to the smartphone, but also has a built-in memory card and a motion sensor. The system starts when someone moves in front of the door, it records the image and saves it. When there is no movement, no recording is made, which is also very convenient.

Now you know what product options are. You need to choose the optimal solution and install it.

We will tell you how to do the installation yourself, based on two options:

classic designs;
digital eyes.

Mounting a regular peephole

Let's figure out how to insert a peephole if you have a new door or there is no installation hole in it given element.

There is nothing difficult in the work, but you need to have a certain set of tools at hand:

Illustration	Description
	Feather drill. With it, we will make a hole on the inside of the door, where the MDF trim is fixed. The standard drill diameter is 20 mm. But if you have an eye of a larger diameter, then the equipment is selected for it.
	Crown for metal. With its help we will drill steel door Therefore, the equipment must be reliable and of high quality. The design consists of a pilot drill and a carbide nozzle with a diameter of 20 mm or more. Advice! Choose a bit with a hex shank, it is much more convenient to clamp it in a screwdriver or drill.
	Screwdriver. It is with his help that we will carry out drilling. The tool must have enough power so that you can drill through metal. If there is no screwdriver, then you can use a small drill, but it is still more convenient to work with a cordless tool, it is lighter and more mobile.
	A drill for metal is necessary in order to pre-drill a hole of small diameter. This will allow you to make even cutouts under the eye, as the crown will not slide over the surface, as it happens without pre-training. You can use options with a diameter of 4 to 6 mm.
	A construction tape measure is necessary in order to be able to determine the exact location of the peephole. If you do everything without measurements, it may turn out that the structure is shifted to the side, and this spoils the appearance of the door.

Naturally, you must also have the peephole itself. Remember that products can have different lengths, because the thickness of the door panels varies over a wide range. In addition, choose the color of the coating, it should be combined with the fittings on your door.

Let's figure out how to assemble a door peephole. The work instructions look like this:

Illustration	Stage description
	The middle of the door leaf is determined. The process is very simple: you need to measure the total width of the door and divide the resulting figure by half. Then a small mark is made on the surface with a pencil or felt-tip pen.
	The height of the eye is determined. It all depends on the average height of those who live in an apartment or house. If family members are of different heights, then you can place the system at a standard height of 150 mm. This is a generally accepted indicator that suits most people. A mark is made at the intersection of the two dimensions. Advice! The mark is best made with a punch, so that a recess remains on the surface, into which it is convenient to place the drill. This is necessary so that it does not slip and scratch the skin.
	A drill with a diameter of up to 6 mm is placed on the screwdriver. Its tip is located on a previously made mark, after which you can get to work. The drill passes through the inner lining of MDF easily and quickly, but the metal lends itself much worse. The most important thing is to make sure that the screwdriver is perpendicular to the surface of the door, otherwise it may be skewed and your peephole will become crooked. Important! The length of the drill must be at least 20 mm longer than the thickness of the door leaf.
	This is what the result looks like. From the outside it should be smooth hole. If burrs have formed on the metal, they can be easily removed. Pass the drill from the outside to the inside - and all the flaws will be removed.
	Next, a crown with a diameter of 20 mm is fixed to the screwdriver. Center drill inserted into a pre-made hole, after which you can get to work. Hold the tool perpendicular to the surface and do not press it too hard, so as not to deform the door leaf and damage the screwdriver. It is better to press with moderate force - the crown selects the metal gradually. Only the outer part of the door leaf needs to be drilled.
	From the inside, the door is drilled with a pen drill. Here it is very important to fix it well and check before work whether it is securely centered. If the drill dangles during rotation, then it must be fixed again. The workflow is simple: as soon as you have passed through the outer skin and insulation, work can be stopped.
	Parts of the peephole are tried on. Everything is simple here: first make sure that the outer part falls into place, then do the same with the inner. If all is well, then you can proceed to the mount.
	The assembly of the structure is very simple: it is necessary, while holding the outer part of the structure, to twist the inner one in a clockwise direction. The work is done by hand, no special tool not required. Screw the peephole all the way in, at the end make sure that it holds well, and the inner cap is in the correct position.
	This is what the door looks like with the peephole installed. If everything is done correctly, then the structure will be tightly pressed to the surface along the entire diameter. In the same way, options with an increased convoy and periscope systems are installed.

Installation of a digital peephole

Now let's figure out how to change the old-style door peephole to a more modern digital version. The work is also not particularly difficult, and the only thing you need is Phillips screwdrivers PH1 and PH2.

As for the process of installing a digital eye, it looks like this:

Illustration	Stage description
	If you have a regular peephole installed, then no alterations are required. If there is no hole in the door, then it must be done according to the same algorithm as described in the section above. The diameter of the hole is selected in accordance with the size of your eye, be sure to check this parameter so as not to redo the work later.
	We check the completeness of the digital eye, you should have the following: Digital display with metal frame for fastening to a door; Camera with a wire to connect to the display; At least two inner bushings for thin and thick door leaf; Assembly instructions in Russian with diagrams.
	Now let's figure out how to disassemble the door peephole. The process is very simple: it is necessary, while holding the outer part of the structure, to unscrew the inner element counterclockwise. If it was not possible to break the mount with your hands, then use a wide screwdriver that can be inserted into the slot from the inside and move from dead center. Further, everything is very easily unscrewed by hand.
	The equipment is being prepared for installation. This applies primarily to the unit with the display. There are two mounting screws at the bottom of it, they are shown in the photo. You need to carefully unscrew them, after which you can remove the body of their installation frame. The screws are very small, so place them so that they don't get lost.
	Next, you need to snap off the mounting frame and set it aside. And four batteries are inserted into the monitor unit. The number of batteries and their configuration may vary, so it's best to first see what you need, and only then buy batteries.
	The outer part of the structure is installed. It looks like a regular peephole, with the only difference being that you need to run a wire through the hole. There is nothing complicated about this, the main thing is to do everything carefully so as not to damage the wire and glass of the camera lens.
	If the lens of an ordinary door peephole can be positioned anywhere, then in the case of a camera, it is important to align it properly. Do not forget about this, so as not to find the image upside down on the display later. Note! The red dot serves as a reference point, it indicates the upper part.
	An internal mounting block is assembled. To do this, the threaded insert is inserted into the hole in the mounting frame. Everything is very simple, the most important thing is to choose the required insert, usually there are two of them in the delivery set: one is designed for thin door panels, and the second for thick ones.
	The inner part of the structure is put in place. The order of work is as follows: First, the camera wire is pulled through the sleeve; On the reverse side of the frame there is a double-sided tape for tight fixation, the protective layer is removed from it, the structure is leveled and pressed against the surface; The sleeve is twisted, everything is like in a regular eye: the outer part is held, and the inner one is wrapped clockwise.
	The system is being tested for functionality. To do this, the camera wire is connected to the connector on the back of the case, and the display is put in its place. Advice! You don’t need to fix anything, first make sure that the structure is level and all functions work. If there are any problems, they are much easier to solve now. If everything is in order, then you can proceed to the last stage.
	Mounting screws are screwed in the bottom of the case. Everything is easy here: check whether the holes match, and carefully screw the fasteners. Note! Do not apply too much force - you can strip the threads in the plastic case.

How to assemble a peephole?

A peephole is a necessary device that fits into the door and allows you to see who is on the landing in front of your door before you open it. The quality of viewing through a peephole depends on the viewing angle. Undoubtedly, the larger it is, the better the place is viewed. The object located in front of the peephole from the outside and the entire surveyed area as a whole will be distinct only in the presence of medium or bright illumination.

All manufacturers of door eyes have their own individual specifics. Therefore, how to assemble a peephole, see the attached instructions for the kit. Door peepholes differ depending on their intended purpose, that is, if you want to provide yourself with, say, outdoor surveillance, then you should purchase secret eyes. Individual peepholes are also designed for double-layer doors, and bulletproof peepholes and periscopes are installed to protect the owner.

Installation Instructions door devices will help you figure out how to install a peephole. In fact, the steps outlined in the instructions are not so difficult and do not take much time. The first thing to do is determine the level at which you will install the peephole. It will be determined by its frequent users, namely children and adults, that is, at what level and depending on their height a person will be able to use it.

After you have marked the location of the eye with a pencil or pen, draw and cut out two templates. Glue them on 2 sides: outer and inner. Make sure that the templates are parallel to each other. Take a drill, insert a drill and make a hole right in the center of the template.

Without putting the drill aside, make four marks on the template with a pencil and drill each of them strictly according to the template. Be careful with the length of the holes. It should be 5 mm, but no more. Before moving on to installing the peephole in the hole, make sure that its outer part fits into the holes made by the drill by disassembling the peephole. Also drill the holes required for the outer and indoor installation door peephole. Clean the place of the eye, removing the dust formed after working with a drill. Install a peephole.

What is a peephole for?

Important! Modern industry offers quite a variety of door peephole options, some of which are equipped with video cameras and other security and control systems.

Design features

Regardless of the type of peephole, its design has a standard set of elements:

A lens that enlarges the image and provides an external view;
External rail holding the lens;
Clamps that firmly hold the lens;
Frame;
Inner nut;
A lens or eyepiece directed into the room;
damper.

The number of lenses in different models and types can vary from 2 to 15 pieces.

Varieties

Door eyes have a large number of varieties, each of which has a special functionality and additional features. Most often, the following types of equipment are installed on the door:

A standard classic peephole installed on a metal or wooden door for more than a dozen years. This device, although it makes it possible to see what is happening behind the door, does not provide sufficient visibility. You can only see what is directly in front of him.
Panoramic peephole. The lens of such an eye has a design divided into two lenses. This allows the lens to take on a large light flux, making the image panoramic. At the same time, it is not necessary to strictly stand close to the door or to the peephole. Everything is visible from different viewing angles.
Peephole door concealed type. Most often, it is disguised as nails included in the door trim, or other decorative elements. Such a device can be equipped with a camera, masked from the outside, if the doors are a continuous sheet.
Bulletproof eye. The name speaks for itself. This element is most often equipped with armored doors that provide maximum protection against unauthorized entry.
Eyelets for double doors. Structurally, such an element consists of two parts and allows you to inspect the external space without opening them.
Periscope. Its peculiarity lies in the fact that the viewing lens and the eyepiece itself are located at different levels.

Attention! This option is especially relevant if the family has small children. You can position the lens at a level convenient for the growth of the child.

Video-eye

In the production of door eyes, modern advanced technologies are also used, the use of which allows you to create practical and functional varieties, among which the video eye is especially popular.

Electronic door peephole

This design also represents an experience in combining electronics and safety features. Door peepholes of electronic type are installed instead of the usual standard peephole. The structure of the external structure includes infrared illumination and light and bell sensors. On the inside of the door, an electronic part of the structure is installed, which is mounted on a metal plate. On this element there is a screen that opens an overview of the stairwell.

Selection and installation rules

Various varieties and price parameters complicate the process of choosing a peephole. To buy high-quality and suitable equipment, you should pay attention to the following parameters:

Viewing angle. The peephole should be chosen according to this criterion, depending on the space near the door. But modern optical devices used in the eyes usually solve this problem at a normal level, providing an optimal viewing angle. In addition, lenses for viewing should clearly show the face of the visitor.
Important! Almost all modern eyes provide a viewing angle of 180 degrees. But there are instances with a large parameter, reaching up to 200 degrees.
door thickness. It can be of a standard type, elongated and exceeding 10 cm. Moreover, the body usually provides for adjusting its length for each type of product.
Light sensitivity. This parameter determines the ability of a clear image transmission in low or dim lighting on the site.
Product width and diameter. If the peephole is already installed immediately on the door, then this parameter is not significant, it is important to know it if replacement is necessary;
The material from which the body of the peephole is made. In most cases, the design is made of metal or plastic. The metal element is more durable, practical and durable, while the plastic one has a lower cost, but a shorter service life;
The material from which the lenses are made. It can be plastic, glass, or optics used in the manufacture of eyeglasses. As a rule, the most expensive options are equipped with optical lenses, the cheaper ones are equipped with plastic ones.

Usually the choice is based on the size of the budget and preferences of the buyer, as well as the required functionality of the device.

Latch on the door peephole

The latch is an important element that is included in the package of most door eyes. It helps to increase passive safety and at the same time performs an aesthetic function by preventing light from entering from outside. Sometimes, instead of a latch, the manufacturer performs mirror-type deposition on the objective lens. It performs the function of a shutter, but may degrade the quality of the view.

Installation Features

Installing or replacing a peephole does not require special skills or experience, this can be done with a drill and masking tape needed to drill a hole.

If the door peephole is not to be replaced, then before buying a new mechanism, remove the old one, accurately measuring its external parameters. If the door has a solid structure and it is decided to install the peephole for the first time, then a hole of the required diameter should be drilled. To do this, in place of the future element for review, a mark is made on which masking tape is attached. After that, a hole is drilled on both sides of the door. From the outside, a tip is installed on which the lens is located. On the inside, a recorder or lens is tightly fixed, which, if necessary, is twisted.

Attention! If you decide to install a video peephole, then it is better to entrust such work to experienced professionals who are familiar with the rules for setting up signal transmission from a device to a monitor or laying a cable.

Reliable protection of the house is an important condition for living in it, and the presence of systems to prevent unwanted intrusions or uninvited guests contribute to the formation of a sense of security. A properly selected and well-installed peephole will help to reliably protect residents.

video peephole and other types, instructions on how to install, dimensions, videos and photos

Think installing a peephole is difficult? The accumulated experience allows me to assert that even an inexperienced master can do this work. I will tell you how to choose high-quality equipment and give instructions with illustrations that will allow even those who have never put a peephole in the door to cope with the work.

The main element of ordinary eyes is a wide-angle fisheye lens, which provides a high-quality view of space. Electronic versions use a camera.

First, let's look at what types of eyes are:

Illustration	Description
	Standard peephole door. This option is simple and consists of two parts - outer and inner, which are twisted together. A lid may be present in the design to close the hole from light penetration.
	Panoramic peephole. Its distinguishing feature is the lens, divided into two lenses. This design allows more light to pass through. To see the image, it is not necessary to stand close, you can be located on the side of the structure.
	Double door system. It can be either standard or panoramic. The design consists of two parts, during installation, special accuracy must be observed so that the elements match.
	Bulletproof option. Used on bulletproof door panels to ensure structural integrity. According to the installation method, it is no different from the usual version.
	Peephole-periscope. This option is ideal for those with small children. You can watch both in the normal position and at the bottom, which is very convenient if you need to exclude the option of opening the door to strangers. The system is quite difficult to install, so most often the work is done by specialists.
	Video peephole of electronic type. Previously, video options required signal settings in order to transmit it to a monitor or TV. Modern technologies have made it possible to make a compact and simple option that anyone can easily install.

If you have decided on the type, it is worth understanding several criteria that are taken into account when choosing:

Viewing angle. The larger it is, the better you can see the space in front of the entrance. For cheap options, the angle is 120 degrees, for more advanced ones - 180 degrees. The highest quality modifications have a view of over 200 degrees, this allows you to eliminate distortion along the edges of the image;

Door leaf thickness. There are three product options:

up to 60 mm;
up to 100 mm;
over 100 mm.

Any version of the eye is adjustable by 20-30 mm due to the thread. In some models, different bushings are supplied so that you can find the best solution for your door;

Eye diameter. This indicator determines the size of the hole to be drilled. If in new designs you can choose any option, then when replacing old elements, it is easiest to choose products of the same size. Most often, the diameter of the inner part is 20 mm;
Manufacturing material. Optics can be plastic or glass, the price of the first option is much lower, but the second is much stronger and more durable. The case can be made of plastic or metal, the second option is preferable, although it costs more.

I will talk about two options for carrying out work: installing a regular peephole and a variant with video surveillance.

Mounting a standard peephole

We will figure out how to install a peephole in a metal door.

Illustration	Stage description
	Measurements are being taken. We are primarily interested in the thickness of the canvas, other dimensions are not so important. Knowing the thickness, you can choose a suitable peephole, and not buy it at random.
	The instrument is being prepared. To do the work yourself, you need the following: Screwdriver with a drill for metal with a diameter of 5 mm; Feather drill with a diameter of 20 mm; Core drill for metal with a diameter of 20 mm; Roulette construction. If the diameter of your eye is larger, then the spade and core drill is selected in accordance with the parameters of the product.
	The center of the door leaf is marked. The eye is usually located in the middle, so use a tape measure and a pencil to mark the middle.
	The height of the eye is noted. The standard option is 150 cm from the floor level, but you can raise or lower the peephole so that its use is as comfortable as possible.
	Drilling is in progress. First of all, a through hole with a diameter of 5 mm must be drilled in a metal door. It is very important to use a drill bit long enough to come out from the back of the door. When drilling, pay special attention to the horizontal position of the screwdriver. If the hole turns out to be skewed, then the eye will become crooked.
	A hole is drilled from the outside. A crown for metal is inserted into a screwdriver or an electric drill, with the help of which the hole expands to the diameter we need. It is important to work carefully so as not to damage the door leaf and not bend it.
	The cladding is drilled from the inside. For work, a pen drill is used, the main thing is to hold the screwdriver evenly so as not to go to the side.
	The hole is cleared of debris and checked. Just look through it, if there are no distortions, then everything is done as it should.
	The eye is fixed. To do this, it should be held from the outside and screwed in from the inside. If there is a key in the kit, then you can additionally clamp the knot from the inside.
	The operation of the system is checked. Close the door and look through the peephole. This completes the installation.

Installation of an electronic peephole

Consider how the camera is installed:

Illustration	Stage description
	This is what the camera kit looks like. It includes: Monitor with control buttons; Accumulator battery; Memory card; Camera; Mounting platform. All you need is a screwdriver to work.
	The battery is inserted. If your system is powered by batteries, then batteries are installed.
	A memory card is inserted. A special slot is provided for it, you will not confuse anything in any case.
	The protective film between the power contacts is removed. Usually there is a tab on the outside that you need to pull and thereby remove the protection from the contacts.
	A sleeve is twisted from the camera. It will hold the element from the inside, so it should be removed in advance.
	The bushing is inserted into the mounting platform of the camera. This completes the preparatory work.
	The platform with the sleeve is placed on the door leaf. For clarity, the work is shown on a transparent module that imitates doors 70 mm thick. Naturally, before changing the system, you need to remove the old peephole. If you have a new door, then all the features of drilling holes are described above, the technology is also suitable for this case.
	A camera is inserted from the outside. It is carefully inserted into the hole, the cable is pulled into the sleeve. After that, the sleeve is twisted to the stop. On the mounting plate and the chamber there can be double-sided adhesive tape for gluing to the door leaf; before mounting the elements, remove the protective layer from it.
	The camera cable is connected to the connector. The photo shows what the connection looks like in our case, but its configuration may differ from different models equipment.
	The camera is installed. It is neatly aligned with the connector, after which it snaps onto the plate.
	The camera is fixed with screws. For reliability, the case is fixed on the plate with two screws.
	The camera turns on. All the features of setting up the system will be prompted by the instruction. You can use the camera as needed, or you can set up a motion sensor and the camera will always turn on when someone passes or stands in front of the door.

Conclusion

You have learned how to install a peephole and you will be able to carry out the work without outside help. The video in this article will help you understand the topic even better, and if something is not clear, ask in the comments.

How to install a peephole in a metal door yourself

realities modern life are associated with constant concern for their own safety and the safety of those close to them. Despite measures taken to protect state law enforcement agencies, the risk of being attacked remains. no exception and own house or an apartment. There is a common opinion: the thicker the door, the higher the security of the apartment. But extraneous noises behind it, knocks, the sound of a doorbell require visual observation of what is happening, an assessment of the potential danger. The installation of a door peephole simplifies the solution of the issue, which will provide a sufficient overview of the staircase or yard area. If it is not available in the installed door, it is enough for the owner to choose the appropriate one by installing it himself.

door with peephole

General information

The design of a classic doorbell includes a body (plastic or metal), two lenses (outer and outer), outer rails, a decorative fastening nut and a protective shutter. The main role is assigned to the quality of the lens. Use plastic or optical glass. Plastic lenses are characterized by low cost, but the disadvantage is a short service life, clouding as a result of dust accumulation provoked by a static magnetic field. Glass lenses have higher rates of transparency, clarity of perception of the visual image, the service life is characterized as significant, but the cost is an order of magnitude higher than plastic ones.

Appearance of the eye

Door peephole selection

The stores offer a wide range of products for this purpose. To determine which one is necessary for the owner of the premises in each particular case, you can familiarize yourself with the types presented below:

standard simple, cheap to purchase, provide a simple overview of the territory;
panoramic, characterized by a wider and better view;
bulletproof;
hidden, placed in a decor element, usually equipped with a micro-camera;

Hidden peephole

spaced apart, used in the presence of two doors, have two parts, viewing from the inner door, and the camera - from the outer;
periscope type, while the parts are at different distances in the vertical or horizontal plane;
video peephole, installed with an additional alarm and image viewing unit, the function of opening the door using a magnetic locking device is often provided.

eye angle

Important when choosing a peephole are the factors that accompany its work in optimal mode:

visual viewing angle, while at least 180 degrees is considered optimal;
the length of the lock structure - should ensure comfortable installation in the front door leaf;
the constructive diameter of the eye, the larger, the better the light transmission of the image;
material.

Door peephole installation

Installing a peephole in a metal door will not be difficult for a person with an initial level of plumbing knowledge and the ability to use a household electric tool. The order of work is as follows:

Alternative Surveillance Systems

Manufacturers, using modern technologies, constantly update the line of surveillance devices. Noteworthy and noteworthy is the installation electronic systems, which perform the functions, along with the main one, of fixing on the control unit the persons approaching the door of the room, a full-fledged recording of the picture of events occurring outside the front door and many others, including an infrared image. But do not forget the fact that even if the system is installed with additional elements power supply - it once ends, and simple optical door eyes do not need them.

Video surveillance system

How to properly install a peephole in a metal door can be understood by watching the video, while receiving recommendations and instructions from the master who has repeatedly carried out this work.

Mounting the peephole iron door

Which visual surveillance system to place on the entrance metal door depends on the degree of its security and the requirements that the owner of the premises makes for such an opportunity, while the financial security of events is also an important component - the more complex the system, the more expensive the purchase.

Door peephole: varieties, device, principle of operation

Electronic type door eyes are considered a kind of novelty that has recently appeared on the modern market. If you use such equipment for the door, then you can make additional protection of the home due to the presence of special functional qualities.

Built-in peephole

The door leaf itself is a design that performs not only a separating function for the room, but also protects it from the penetration of unwanted guests. Many believe that if the thickness of the door leaf is greater, then it is stronger. And that means better protection of the room. In some cases, landlords are required to know what is happening behind their installed door. Let's consider such cases:

Extraneous sounds respond behind the door leaf;
Someone rings the doorbell and is silent after that.

A common method of reviewing what is happening behind the front door is installing a peephole. Door eyes were used back in the 60s of the last century. A peephole was invented for installation on a door by an American scientist named Robert Wood. Initially, the types of door eyes were primitive. The first of these was called "fisheye". Only with the passage of time, the door peephole device began to be used to equip doors in houses or apartments.

What is the device made of?

Attention! Currently, door eyes are purchased without problems, since the range that is offered to the buyer is so wide that everyone will select the device according to their individual characteristics.

To better understand the device, consider its basic design:

A lens that is brought out;
Lath of the external direction;
Elements with the help of which the main lens is fixed;
Mounting internal elements;
Inner lens;
Damper (it all depends on the configuration, this element is optional).

Shutter option

The main aspects that are paid attention to when choosing a door eye are ordinary and panoramic

Inside its device, a door panoramic peephole has lenses in an amount of up to 15 pieces. The required amount depends directly on the case. But there are also individual factors that are paid attention to in the selection process:

Angle for viewing. Often this indicator should correspond to the area that is viewed with the help of a peephole. In this way, maximum efficiency and safety are obtained. In addition, with the help of a lens, the face of the one who is standing outside the door is clearly visible;
As for the preference for the optimal indicator, it is 180 degrees for review. Some manufacturers, in order to remove small flaws that have a 180 degree peephole, made it 200 degrees. But there are not so many such models at present, therefore optimal angle to view the entire area, it still becomes 180 degrees.

An essential factor when choosing a peephole for a door leaf is determining the width of the sash. If we consider standard indicators, then there are three common options:

Standard type construction. This type is used for door leaf with a standard thickness;
Extended version. The thickness is more than the prescribed standard;
Long variant. Such a peephole is installed if the door leaf has a thickness of more than 10 centimeters.

Devices with standard parameters are becoming common. Such types are used for canvas made of solid or metal. As for the adjustment, it is made using a special thread that each eyelet has as standard.

Attention! If the door leaf is subsequently insulated, then the length of such an eye will be small.

It is not enough to fix the equipment correctly, you also need to take into account the width and diameter that the structure has. And all due to the fact that if the diameter and design do not match in terms of parameters, then the visibility will be greatly distorted.
The material that is used in the manufacturing process becomes decisive in the installation and selection process. If pick up wrong material for production, the design will not work for a long time. Two main types of material for production are most often used: plastic or metal. As for the metal, it is, of course, durable and is not affected by external factors. If you pay attention to plastic, then over time it lends itself to deformation or cracking. The material is destroyed and this can happen due to temperature changes;
The materials from which viewing lenses are made also play a significant role in the full functioning of all equipment as a whole. Of course, the quality of such material also affects the cost of the peephole in its complete set. If we consider the materials that are used for such purposes, then the following are distinguished: plastic, ordinary glass or optics, which is also used in the production of glasses.

Peephole made of plastic material

How to choose a peephole? Main varieties and models

Panoramic option. The first aspect by which this option is distinguished from the rest is that the device is equipped with two lenses. With this design, the lens has the ability to receive a large number of light fluxes, and then a panoramic image is supplied. To view the image, it is not necessary to be opposite the eye or close to it;

Panoramic view

Bulletproof peephole. The functional actions of the device are clear, based on the name. That is, they can assemble such a design for those canvases that need additional protection. Such a peephole is installed in order to obtain the highest degree of security;
Hidden type. More often, this option is disguised as nails that are in the finishing material of the canvas. Often this option is a kind of micro-type camera. That is, a reader is outside, and a recorder is on the inside;
View used for double door leaf. With the help of this type, they look through the site without opening inner door. At the heart of the design has two main parts;
Periscopic peephole. This equipment option has a lens, as well as an eyepiece at different levels. More often, the use of such a device occurs in a room where there are small children due to the fact that it is possible to place parts of the equipment at a level convenient for viewing.

periscope type

Door peephole installation

To install such protective equipment, you do not need to have any special skills. If a peephole is already installed in the door and it should be replaced, then initially deal with the question: how can I remove the old peephole from the door? It's simple - the structure is removed from the hole. If there is no hole, then it is pre-drilled in the canvas.

Before drilling a hole, choose a place where the device will be located. Make a mark at this place with construction tape;
After that, on one and the second side, make holes of the required diameter;
On the outside, place the tip on which the lens is located, and on the inside, the “registrar” is mounted.

Positive and negative qualities that a peephole has

With the help of this type of equipment, without opening the door leaf, a platform is visible, which is located behind closed door;
A wide range of devices, with the help of which any individual option is selected.

If we consider all of the above, then we can say that the peephole was and is a universal device, with the help of which additional security of the premises is carried out. Check out our video for a detailed review.

door peepholes

requirements for doors

A simple peephole device allows you to see the space of the landing without opening the front door. And, although the front door itself is able to protect the house from uninvited guests, it is always good to see who is standing outside the door and knocking on your house.

That is why the door peephole should give a clear and most complete image of objects located at a distance of 0.5 to 5.0 meters in front of the door in conditions of medium and bright illumination. Today, there are special door peepholes that can provide a view of the space even through double doors.

There are also models (the so-called secret eyes) that make it possible to guarantee stealth for observation. In addition, periscope eyes and bulletproof eyes are currently being produced, which guarantee the protection of the owners of the house during observation. Often door peepholes duplicate television surveillance systems, which also increases the overall protection of the house.

At the same time, it is very important to right choice door peephole. But first, let's figure out what the peephole device, which is familiar to us, is.

Door peephole device

Although the design of door eyes can be very diverse, but general device, as the experience of recent decades shows, is approximately always the same. So, all door eyes consist of an eyepiece (a lens facing the eye of the observer) and an objective (a lens facing the observed object).

In this case, the device of the door eye implies that other lenses can be placed between the lens and the eyepiece. The mechanical design of most of the eyes includes the presence of an outer nut body and an inner nut. It has been observed that the total number of lenses in the eyes ranges from 2 to 15 pieces.

In the door eyes special purpose(such as peepholes-periscopes) use systems of mirrors. The most common door peephole device today is the design of the optical system, which consists of four lenses, which allow for a viewing angle of approximately 180 without significant image distortion.

Also, the device of almost any door peephole today includes the so-called dampers. Without this component, only the cheapest products of this class of goods are currently produced. The role of the damper is quite large: it does not let light in from the apartment and allows the owner of the apartment to secretly approach the peephole and, without revealing himself, monitor the site.

The main requirements for the damper design are that it should close the peephole opening, open and close silently and easily, and during its movement, due to the absence of sharp corners, it should not come into contact with the door or its upholstery.

Door peephole selection

When choosing a door peephole, it is better to immediately find out which viewing angle of the peephole suits you the most. You also need to immediately determine the diameter of the eye. If, for example, the diameter of the hole in the door of your house is larger than the purchased peephole, then there will be only one way out - to return to the store and change the peephole to a model with a larger diameter.

Since the main characteristic of the peephole is the viewing angle, then, of course, the larger it is, the better. The largest viewing angle is 180°: with such an eyepiece, even the rug lying under the door is clearly visible. The smallest angle of inclination is considered to be an angle of about 120 °.

In addition to the required viewing angle and eye diameter, at the stage of choosing a model, you need to decide on the thickness of the door: this indicator is also very important. For ordinary doors, the thickness, as a rule, varies from 35 to 60 mm, for good, reinforced doors, it can be up to 85 mm.

Based on these parameters, the "trunks" of door eyes can be very different in length and very different in diameter, so that you can choose a peephole for any door. In addition, the peephole device includes a thread that regulates the length of the model. According to this parameter, all eyes can be divided into three main groups: standard eyes for doors with a thickness of 30–55 mm, elongated eyes for doors with a thickness of 55–100 mm, and extra-long eyes for doors with a thickness of more than 100 mm.

According to its material of manufacture, the optics of the door eye can be plastic or glass. It is believed that glass models are more durable, as glass is less scratched. The "body" of the peephole is usually made of metal or plastic. Therefore, when choosing a peephole, pay attention to the material from which the model is made, as this affects the quality of the device and its price. Experts note that glass and metal eyes are the most reliable, but at the same time the most expensive.

The appearance of the product also depends on the quality and type of coating of the eye to a greater extent: it is necessary that it harmoniously fit into overall design entrance door. At the same time, it was noticed that often a peephole made of ferrous metal with a coating looks better than a door peephole made of non-ferrous metal, but without a coating. It should also be noted that door eyes made of brass with imitation of gold can darken over time, and eyes made of steel with chrome and titanium coating are practically not subject to scratches and do not darken.

Let your choice of door eyes, taking into account our advice, be the right one.

The door peephole has long become the same necessary accessory of the front door as the lock. It is one of the simplest and most accessible elements that ensure our security. The door peephole makes it possible to protect yourself from the visits of unexpected or unwanted guests. In addition, it allows you to assess the situation on the site in front of the door in case of any problems.

Classic door peephole

design

The design of a standard door peephole is simple:

Lens - located on the side of the site in front of the entrance and provides its overview;

Eyepiece - located on the inside of the door;

Tube with lenses;

Nuts - external and internal.

The largest view that a convex outer lens has is considered to be an angle of 180º. But due to the fact that the picture around the edge is slightly blurry, many manufacturers began to produce eyes with a viewing angle of 200º. When using such a device, you can get a high-quality, clear image of the site in front of the door within 5 m.

The length of the peephole depends on the thickness of the door:

30-50 mm - standard;

55-100 mm - elongated;

From 100 mm - extra long.

Standard devices usually have 4 lenses, but depending on the length of the peephole body, their number in it can be different - from 3 to 15 pieces.

Elongated and extra long eyes are used for doors with various decorative coatings. Most often, standard devices are used. They are quite enough for ordinary metal or wooden doors.

In order to be able to quietly approach the peephole, it is equipped with curtains that do not let light in from the apartment.

production material

The body of the peephole is made of metal or plastic. The first option is more expensive, but will last much longer. The eyepieces of the device can be glass or plastic. The latter are more resistant to damage, but they can become cloudy over time and the image will lose clarity. Metal models with glass lenses are more expensive than plastic counterparts, but this is justified by their quality and reliability. There are bulletproof and impact-resistant eyes, but such properties of products, of course, are reflected in their price.

door peephole installation
