How to assemble the door of the door - types of structures and installation recommendations. How to install door eyes in a metal door yourself

Eyes, as well as when it is selected and install, should be guided by the safety and conditions of the maximum area review, taking into account the material actually entrance door. Dear S. maximum level The review has an angle of 180 degrees, which allows you to view the site up to your rug. The panoramic viewing angle of cheaper options is about 120 degrees and special advantages in any effectiveness, nor as viewing the site does not give.

Today, video eyes are quite popular with a built-in camera connected to a computer or laptop by type of standard webcam.

If you are going to buy and install peepholeDo not forget to take into account the thickness of the canvas of your door. The length of the eye housing and its diameter you can easily choose from a wide range. Remember that the length of the eye can be additionally adjusted by carving on its body.

Traditionally, the door eyes are made of plastic and metal, while their optics happens to glass and polymer (as well as plastic). The advantages of glass optics lies in a better image, resistance to mechanical damage (scratches and dusting), as well as in the absence of turbidity.

The eyes, the most optimal in terms of their qualities and characteristics, have a metal case and glass, but the cost of them is higher than that of the budget models of the door.

Installation at door

Installation of the eye on the door is carried out taking into account the growth of the owner of the apartment. It should be noted on the door of the center, based on the desired height, and outlaw the resulting mark - it will not slide. Also before marking a place to install, glue on the selected area door canvas Striped adhesive tape. Now you can put back, without fear to spoil the door facing.

So that the chipsets are not formed when drilling in the door, the layout of the future hole is performed on both sides of the door.

By selecting the diameter of the drill (slightly more than the diameter of the threaded eye element), start to pick up the placed holes on each side of the door, immersing the drill on half the door canvase thickness. Sculpt the eyes and install the outside part from outdoor thread, and part with internal thread - From the inside. After the holes are climbed, screw into the peel into the door, tighten it with a slot and enjoy a safe overview of the staircase area.

The entrance door protects real estate from the outside intervention. She protects households from outsided people. But know what is being done near the apartment or at home, it is also necessary. For this apply door eyes. According to the standards, 0.5-3 meters of near-door space should be viewed through them. Sold various models With interesting features: for a double door (installed immediately in two panels), hidden (it is unobedient to others), protective (bulletproof). Optics occurs, which performs the functions of alarm.

Eye of the door was created by Tester Robert Wood. It happened in 1906, but to use the technology began only after 1960.

Simple system consists of:

• lens lens that expands overview outside the apartment;
• outdoor rail fixing it;
• lateral locks lenses;
• hull;
• internal nut connecting the external and inner lens among themselves;
• eyepiece, which is directed inside;
• damper.

The smaller the door thickness, the less the case will be, less lenses will be installed in it. Models that are sold in stores have from 2 to 15 eyepieces.

Main characteristics

Characteristics include length, angle, manufacturing material, diameter, variation of the valve. The parameters are chosen depending on the type of door to which the equipment is mounted. The functions that the device must perform are also taken into account.

Length of the eye

Length depends on the thickness of the door. For this character, all models are divided into:

• standard - from 30 to 55 mm;
• long - from 55 to 100 mm;
• super long - from 100 mm.

For apartment doors, it is enough of the standard set.

If the doors are additionally offended by bulk materials, the eyes of the eye to 55 mm are not enough. Therefore, they use long or super-long options.

Corner view

Standard, the viewing angle is 180 degrees. This is possible due to the transfer of the focus of the lens up, but the structural features distort the incoming rays. Manufacturers compensate for errors, increasing the viewing angle of up to 200 degrees to achieve an indicator of 180 degrees.

Long and super long eyes have other optical parameters. Some firms sell equipment in which the optics are equipped with a rear nut. The optical scheme does not change.

Material execution

According to the manufacturing material, there are models with plastic or glass optics. The equipment is divided into such subspecies:

• two nuts and hull - plastic;
• inner nut and case - plastic, the remaining parts are metal;
• two nuts and housing - metal.

The larger the metal is used in production, the higher the cost of the product. The enemy of their silhouette lithium will cost cheaper, more expensive - from black metal.

The optics of glass gives a good image, not blurred, but it is rather fragile. Plastic is not afraid of shocks, but scratches remain. The image is not so clear. In addition, over time, yellow occurs.

Product diameter

Diameter of door optics is different. In standard variations, it ranges from 2 to 3 centimeters. Manufacturers produce models whose diameter exceeds 5 centimeters.

Eye catch, analogues

The valves and dampers allow you to imperceptibly observe and protect the apartment from light. Properly installed valve:

• has no acute corners;
• closely closes and does not allow the light rays from the entrance;
• when opening and closing does not contact with optics and door.

An analogue of the valve - a mirror spray. It makes the image less bright and clear. At the same time, the buyer of the model with a mirror spraying is not experiencing that the damper scratches the accessories.

Types of door eye

The view that has simple design and an angle of review 180 degrees is considered standard. Other models were developed that work in the same way, but at the same time increase the viewing angle and give large defense. Among them:

• or fishery, which has two lenses - the near-door space is visible better;
• a bulletproof version from special durable materials that protects people from intruders;
• counted, which is in an unexpected place, because of what is unobedient to others;
• double - Designed for a double door, allows you to see what is happening for the outer door;
• periskop - convenient for families with small growth children or people with disabilities (conveniently viewed from a low distance);
• which is a miniature copy of the simplest video surveillance camera;
• the model with the motion sensor notifies the owners when the door occurs.

Smart species are capable of tracking what is happening in the entrance and record information on the external drive. They consist of a chamber, monitor, power supply. The microscopic chamber is placed inside the eye. Equipment unnoticed.

How to choose?

When choosing the door option, it is important to take into account specifications. Among them important parameter - Viewing angle. Standard options give 180 degrees. It does not allow to provide reliable protection. Periscopes, telescopic nozzles allow you to increase the viewing angle, make a visible space near the door itself. Also worth paying attention to:

• Photosensitivity. This data is written in the parameters. If they are high, then you can consider what is happening outside the door with minimal entry lighting.
• Type of shell. Models without a housing are easier to install and install, but corps are reliable.
• Production material. Longer serve hardware. Plastic are not reliable, although they are cheaper.

Door optics are selected based on design features and protection requirements. Buy a modern version for ordinary apartment irrational. Simple is clearly not suitable if there are many valuable things at home. So that foreign people do not penetrate the dwelling, it is better to buy high-quality equipment.

Installation of the door eye

Installation of standard equipment happens quickly. This can be done independently. Electronic videos, which transmit information to the digital screen, are mounted longer, because the wizard paves the cable from the door to the recorder according to the scheme. The order of work when installing a simple eye is as follows:

• applying the door markup in the selected place;
• drilling hole with a perforator or drill (size depending on the size of the eye);
• installation on the outside;
• twisting base on the inside.

Installation, assembly of periscopes, double models, smart door eye better entrust to professionals. They will be able to assemble them reliably.

Those who are a little familiar with a locksmith can be mounted independently, adhering to instructions. Need a drill or perforator, a ruler for measuring, level. When working, you need to observe the boundaries so that the eyes do not hesitate and tightly in contact with the upholstery.

Manufacturers

Select any one manufacturer as the best, it is impossible. Buyer's strategy - to explore the parameters and characteristics of the product. After that, to decide how much products are suitable for the requirements. Famous manufacturers:

1. German abus. Collected equipment is durable. There are eyes for private apartments and country houses.
2. Chinese armadillo. It provides a ruler of good goods. There are eyes from various materials, interesting colors, sizes. There are additional features.
3. Russian Nora-M, Doorlock, Apecs, Taper. The eyes are distinguished by the favorable ratio of quality and cost. In stock Certificates corresponding to GOST.

So that the equipment fully satisfied the buyer, it is important to take into account, for what purposes it will be used. It is possible to do with standard options if there is a central castle on the entrance. How to choose the right eye - the question is relevant if people live in a disadvantaged area. In this case, it is better to make attention to modern corpus models. The right eye of the guard of property will help control the safety in an apartment or home.

Door eye - part of the entrance door, without which we have not been able to see a long time. This is a kind of passing in our dwelling: we see guests and decide, we want to let it inside or not. Modern door eye models and allow you to monitor what is happening on staircase remotely, from the office or being on vacation. The market provides a huge selection, so you can find something like, inquiries and wallet.

How is the door peephole

Do not forget that the door eye is an optical device. Therefore, it cannot function without two main components: eyepiece and lens. The eye body can be made of metal or plastic. Choosing quality, give preference to the metal.

"Fish eye" - also an integral part of the classic door eye. It is intended to increase the image, so people through their eyes seem significantly more. Also in the case placed lenses, from two to fifteen pieces. The number of lenses depends on the length of the device and is responsible for the light.

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

The size of the device varies from the thickness of the door canvase. Metal canvas thinner, but in modern doors Practiced multi-layered, so steel door May be thicker old wooden. The next size door eyes are distinguished:

• 30-55 mm. This is the thickness of the standard entrance door;
• 55-100 mm. Doors with trim or decorative elements;
• More than 100 mm. Armored doors, which are more often used on protected objects, in warehouses for especially valuable goods.

The eye viewing angle fluctuates from 150 to 200 degrees. It is optimal to consider an overview of 180 degrees: so you will see a person and a significant part of the staircase.

When choosing a door eye special attention Pay the class of the door itself.

Door Eye: Views

Standard. The eyepiece and lens form a single line, and are located opposite each other. The easiest and affordable eye option. It is customary to install on simple models Doors. But even taking into account the availability of this model, we recommend choosing eyes with glass lenses and a metal case - they will serve longer.

Periscopic. Represents more complex design. From the inside there are two eyepieces, and with an external lens. The image transmission to the second eyepiece is performed using mirror lenses. Why do you need such a design? For convenient operation by residents of different growth. If the family has a child and you are afraid to leave him one because he will not be able to look at the door eye - install a periscopic model, for its convenience.

Secret. The outer part of such an eye is located outside the door leaf, usually above or on the ends. Outside, no one guess that a resident of the house can observe.

Panoramic. A large eyepiece, a large diameter of the case and the ability to watch "in both eyes" are dying with difficulties in the installation. Inside the design there are transmit lenses. But the viewing angle is extremely great - you see the entire staircase.

Electronic eye with a video camera. The most modern view of the door eye. It has the function of video filming, recording and even broadcast. Therefore, you can easily find out what happened on the playground in your absence. This look of the eye we will look at in more detail at the end of the article.

Installation of the eye in the metal door

The principle of installation of the door eye is identical for doors from any material, whether steel, wood or veneer. When working with the metal, there is only one principal difference - the thickness of the door and the density of the material. Therefore, you will have to spend more effort and choose a larger eye model. Moreover, metal doors are often complemented. internal trim From MDF and decorative elements that somewhat complicates the task.

Installations of the Overview Device in metal door:

1. With the help of chalk or pencil, mark the location of the future eye. Consider the growth of all family members and choose the average value.
2. To avoid deformation of the interior of the door or its coating, turn the film or isolate at the drilling site.
3. Measure the chassis diameter of the eye. If the details have an internal thread - use the drill wider than the result obtained per half of the millimeter.
4. You need to drill from the inside, directing the drill to the outside of the door.
5. Do not recruit the door through. Get to the outer layer exterior decoration And stop. Then make drilling with outside. This small trick will help to avoid the formation of jar, chipping and irregularities.
6. From the outside the lens is established. With internal, respectively, eyepiece.
7. Connect both part of the eye screwing movements.

Electronic door eye: species, advantages, installation

Visual viscosity is a complex type of device that makes life safer. Unlike classic analogues, electronic eye is easy to operate and has an impressive set of functions.

Views

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

1. Wireless with color recording feature.Installed as ordinary eye. The image quality is inferior to monochrome and costs more. But it has a function of video in color.
2. Monochrome, infrared.Simple installation, IR illumination, convenience in operation. Monochrome eye will become worthy alternative ordinary.
3. Electronic black and white eyes complete with a matrix chamber.Complex installation, image distortion, small monitor. Of the advantages - affordable price.

Benefits

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

• Conclusion image on the monitor. It is convenient to those who do not like to pushed and close one eye. From the convenient distance, the panorama of the staircase is visible.
• Night vision feature. IR illumination is convenient at night when ordinary eyes simply cannot cope with its main task.
• Recording feature. It is suitable for those who particularly relate to security. You can be on the other end of the world, but to know exactly what is happening in your stairwell and who comes to the apartment's entrance door. How it works? The eye connects to a computer or to another device for storing data. Also in each model with the recording function there is a microSD card slot.
• Built-in motion sensors. Additional bonus in the security system of the security system. Even in the dark, you will learn that there is someone next to the door. The system is adaptive for both residential facilities and for office premises and warehouses. It is an excellent addition to the main system alarm system.
• No need to make a license. Classic systems Video surveillance is subject to compulsory licensing in some cases. The use of electronic eye with the video function does not require license. This is relevant for any purpose from private to commercial.

Installation of electronic eye in the rail door

Different types of electronic eyes are installed according to one principle. However, each of them is worth keeping the individual subtleties that we will tell below.

Install the accurate thickness of the front door. In most cases, the video table includes transition rings, but even they are calculated under a certain size of the door canvase.

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

Next, set the camera into the hole and fix the monitor. Typically, the kit includes special bolts that are easily screwed by a screwdriver. If the peephole is wireless, the fastening of the housing will become the final stage of mounting.

Some models are attached to the door itself either next to the hole from the old eye. You need to carefully read the instructions, and it is better to turn to a specialist.

There are also models operating from the network. With them, additional manipulations are made to connect and disguise the wires. Such devices are not recommended independently.

Connect video video: video

The choice of complexity, price and type of door eye depends on factors such as: doors class, financial capabilities and need to improve security. Take into account the ratio of all these parameters during the choice and installation. Metal doors Gardian correspond to its technical characteristics Any type of eye. In order to improve security, you can order a door with an additional armored web or decorative elements to your taste.

Our life is now such that you can open the door to the guest only for sure to make sure that one actually stands on that side of that direction. Hear a familiar voice, of course, well ... But, as they say, "to see once ...". And there is nothing gallopped here - "God saved!". Because the door eye is a necessityDigitalized by harsh time. It is not so expensive, but install the door eye in the linen of the entrance door can be.

The eyes are on sale are of a variety of and in size, and in size and price. You can choose any, the main thing is that its installation dimensions correspond to the thickness of the canvas of your input door. But, as a rule, they can almost vary in wide limits.

It is also desirable that the angle of sight of view is at least 170 ° (such eyes are also called wide angular). Then the "guest" does not hide from you and clinging to the wall at the door. And it is better if the outer lens is made of glass, and not from plastic, it scratches less, and therefore durable.

How to install door peephole with your own hands

	So as not to spoil with the layout of the door leaf, on the desired height Stick striped with paper adhesive tape, for example, painting. On it any affordable way Place the position of the center of the opening under the eyes.
	Measuring the landing diameter of the eye (in the part with the internal thread), pick up the drill slightly larger diameter - by 0.3-0.5 mm, the best - screw or corkscrew.
	Drilling the doorbell do not throughout, but only that the instrument guide center is outward, the drilling of the hole continues from the opposite side. Due to this, it will be possible to avoid the veneer pump on the front surfaces of the door.
	Establishing the eyes into two parts, one (with an outer thread) is inserted from the outer side of the door web, and the other, respectively, with the inner, and swing them from hand.
	Tighten the eyes using slots on its inner rim. So that the screwdriver is not broken, her sting should be in both slots. You can simply take a steel plate of suitable thickness.

Why call the wizard, if you can cut the eyes yourself.
So considers the majority who ever held a plumbing or carpentry tool in their hands, but not as a specialist, but as an amateur.
If someone had ever had to do this issue, then he would definitely say that let everyone do their own business.

How easy it is simply or difficult to embed the eye in the door, if there is no experience.

To begin with, we will understand and clarify which door and what material it is made.
If the door is wooden, then this is one, and if metallic, then it is completely different.
At first glance, it may seem that in the metal door to cut the eyes more difficult. But here just everything can be the opposite.

Difficulty single eye in a metal door It can only be in the strength of the metal, and everything else, most likely, will go like oil.
Yes, the hole in the thick gland is not easy to drill, and who said that the door is thick steel.
As a rule, conventional entrance doors are made of metal with a thickness of no more than 2 mm.
Make a hole under the eyes in such a thickness is not a serious obstacle for a person armed with a modern tool.

There is one small one, but very an important nuance.
Drilling a hole in metal without having experience is extremely dangerous for both the door itself and for the master.
At the outlet, the drill can jam and break it may be seriously injured or injury.
It can also happen a metal break and instead of a neat hole
The hole will be like a chamomile.

I will not add and warn if the door has decorative finish.
When not compliance with everyone necessary when poking finishing material May suffer, and then the costs of facing also will be added.
In a word for such a minor procedure as a knocking, it is necessary to prepare thoroughly and if there is the slightest doubt in the positive completion of this issue, it is better not to take.

One of the cheapest, but sufficiently reliable ways to protect the attackers is the door to the door.

The embedded in the eyepiece allows you to see what happens when landing to "identify" your visitors and, if necessary, view the documents that are presented without opening the door.

These products are very wide in the market. There are very cheap and very dear models. Let's try to find out what distinguishes from each other and does it make sense to pay more.

The first products of this kind, which appeared in our country, could not provide complete safety.

The attackers learned to simply "deceive" them. To avoid look, it was enough to cuddle to the wall at the door or sit on the threshold. This feature is the result of a small angle of view of cheap products.
Specialists are recommended mounting lugswhich looks like 180-220 degrees. It is better, better. You also need to take into account the fact that the edges of the image are almost always blurred.

How to install pefoles in metal doors

It seems that some areas fall in sight, but what is happening there is almost impossible.

Maximum visible angle without blur panoramiceyes. This is due to the fact that the product lens consists of two lenses - left and right. In addition, you do not need to get to the door and click on the eyes to get a picture.

The distance on which the survey is possible depends on the model and can vary from one step to one and a half.

Before buying and trimming the case through the door, you need to understand what functions should be considered when choosing.
From the point of view, which he has already identified, we are now talking about the materials.

The body of the product can be made of plastic or metal. The first is cheaper, but not very strong.

Metal models are much more reliable.
Lens are the main part of the product. Their quality and quantity depend on the clarity of the image. They can be made of plastic, ordinary glasses or glasses.
The first is the cheapest, the last one is the most expensive. Plastic lenses initially provide light stream.

In addition, they are able to accumulate static electricity, which attracts dust particles. And the material itself ultimately becomes destructive and loses its transparency. In a word, after a few years, images transmitted by such lenses become vague and unclear.
More recommended tie With the lenses from ordinary glass.

And the best option is products from special glasses. Fully transmits the light stream and is characterized by increased power.

Of course, such models are the most expensive.

But they will regularly serve for many years.

Shielded eyes can be used for objects requiring serious precautions. Inside such products is a layer of transparent glass-pressure glass. This does not affect the quality of the image and can remain the focus with the help of a short firearm (pistol).

And the last factor that can affect the choice is the length of the eyelids.

Standard models are designed for the doors with a thickness of 35-50 mm, but the products also have a length of up to 100 mm.
Eyes for thicker doors in retail store rarely accepted. Most often they need to be ordered.


Summing up, we can say that the best way Provide our own security - create panoramic eye.

Higher comfort and viewing angle allow you to receive only electronic models with a video camera and a liquid crystal display, but their price is much higher.

Entrance doors are the border between the personal space in the house and the outside world and the stronger the feeling of comfort and the security is stronger, but sometimes there is a situation when the owner needs to see and hear what happens beyond his apartment. Optimal decision This problem is the installation of the door eye, the history of the creation of which is leaving in the distant 1906.

It was then that Robert Wood was invented by a wide-angle lens, called the "Fish Eye". Gradually, the discovery was improved until the modern version of the door eye was turned out. To date, the door eye can be purchased by choosing from the entire range strictly according to individual preferences of form, size and functionality.

How is the door peephole

Design modern model The door eye consists of the following details: two lenses fixed on the sides for comfort.

One of which is directed to the external object, and the second inside is the eyepiece. For fastening, an outdoor rail and an inner nut are used. The lenses are hidden in the case, while its length depends the number of lenses that can be installed there, usually this number varies from 2 to 15 pieces, on which the flap is located on the inside.

Types and criteria for door eye

At the time of buying specific model Eye, it is worth considering several of the main criteria so that any situation can not catch surprise. Being a conductor through the door, the viewing angles play an important role, and the higher the level of risk.

Thanks to an enlarged field of view, you can observe the maximum space in all directions and all that happens on it. The optimal view for the review is 180 °, but quite often it is expanding it to 200 to optimize the image quality and eliminate distortion in the visibility field.

The cunning to which most producers resorted is the focus extension that ensures more coverage. The following factor is the width of the door canvase, from which the eye model depends: standard (for the door with a thickness of 30-55mm); elongated (for the door with a thickness of 55-100mm); Long (within 100mm).

Standard eyes are considered the most common model, which are installed in modern samples of metal and wooden door canvases.

For adjustment under the individual door width, a thread is used, with which you can fix the desired position. It is worth paying attention to the insulation, unless of course it will be used in the near future, because it will add "width", and the calculated length of the standard eye may be insufficient.

Secret good shopping The door eye elongated or an over long model lies in its optical characteristics different from the standard options. But most manufacturers, in order to save materials, prefers a complete set of conventional, elongated nut, while not taking into account the decline in image quality.

The diameter of the eye plays a small role, while the utility coefficient is higher than it is greater. Thanks to the Lens Lens, the clarity of the image rises, and from the distance to 7 cm from the eye will save its properties wide corner For review. The only nuance minus in the eyes with a wide diameter of them cannot be replaced by a model with a smaller diameter.

Materials manufacture glaze

The most popular material for the manufacture of door eyes is still plastic and metal, which ultimately affects the cost of a model.

Here you can do without any comments, because many will agree that metal products are durable and stable, which cannot be said about plastics, prone to deformation and cracks.

Installation of the door eye

The same applies to the lenses themselves. Rational to acquire eyes with objects from ordinary glass or spectacular optics, which, unlike plastic analogs, is not thrown and not deformed and at careful handling will serve quite a long time, paying for its value.

Door eyes

1. Task

The door is designed for visual observation of limited space and, as a rule, is installed at the entrance doors of private and public premises.
Neck eye should give a clear picture of objects at a distance from 0.5 to 5.0 m under conditions of lighting and lighting.

Special door eyes can also be observed through double doors (eye for double door), security control (eye secret) observer (bulletproof eyes and eye periscopes), etc. Doors are often duplicated by the television monitoring system, whose work is less reliable.

second

Device neck.

The OKANCE design can be completely different, but in everything that is a small eye eye (the lens is turned around the observer) and the lens (lens addressed to the observed object). There may be other lenses between the eyepiece and the lens. In addition, the optical part of the most attractive structure includes: a hull having an external and internal nut. (Fig. 1).

The total number of lenses in the door hesitates from 2 to 15.

Sometimes mirrors are used in the doors (eye periscoves).
The most common is the design of an optical system consisting of four lenses, which provides an angle of 180-200 degrees. Without significant image distortion (Fig. 2).

3. Consumer eye neck properties

Thickness of neck It is one of the main parameters of the eye of the cervix. According to this parameter, the eyes are divided into three groups:
- standard eyes (neck thickness 30 - 55 mm);
- oblong eyes (neck thickness 55-100 mm);
- Extremely long eyebrows (door thickness more than 100 mm).
Most of the doors manufactured are "standard". These eyes can be placed on modern standard wooden doors and in most metal doors.
If the door is finished with various solids and soft materials, the length of the "standard" eye may be insufficient.

In this case, it is necessary to install "long" or "very long" cervical eyes.

Cutting the eye into metal doors or problems of people with a slight increase

Tilt angle Neck eye is shown in FIG.
The ideal view of the neck view is 180 degrees. Large, if you look, is achieved by "moving forward" in the center of the lens. It provides a complete picture of the door zone.
However, it should be borne in mind that in the view of the doors at the edges of the field of view often arises an image distortion. Therefore, the majority wide Agricultural Eye Made with an overestimated angle of review -200 degrees, which reduces distortions in the "working" sector - 180 degrees.
Choosing an "elongated" or "very long" neck, we must not forget that these eyes should have different optical properties than "standard" eyes.

It is not always noticeable. Some manufacturers produce "oblong" eyes, fill the "standard" eyes with an elongated rear nut without changing the optical scheme. Installation of eyelets with such a bundle on a wide door leads to a sharp decrease in the viewing angle.
Choosing a box, you must check it at a visible angle as much as possible, unscrewing the inner eye, t.

maximizing the "door thickness" parameter.

3.3. Construction of crushers.

Currently, almost all your eyes are equipped with blinds. Without throttle, only cheap eyes are produced.
The damper does not allocate light from the apartment and allows the observer to be unclear to the eye and watch secretly.
Basic requirements for flap design. Loputs Mora:
- close the eye hole;
- easy and quiet discovery and closure;
- They have no sharp corners;
- Do not touch the door or the gate canvas while driving.
The last requirement is often not provided in the design of modern and holes leading to difficulties when the valve is rotated, damage the door surface, the door trim is cutting soft and in the end, damage to the flap.

materialswhich are used in the manufacture of cervical eye, largely determine the sale price of the eye.
Below is a list of materials used to form your neck eye.

The list is made after an increase in eye prices:
Glasses with plastic optics:
1. Housing and two nuts (external and internal) - plastic;
2. Case and inner nut - plastic, outdoor nut - metal;
the third

Case and two metal nuts.

Glasses with a glass option:
4. Case and two nuts (external and internal) - plastic;
fifty

Housing and inner nut - plastic, outer nut - metal;
6. Case and two metal nuts.
On the other hand, metal eyes are different, one in the form of metal,
processing method and coating type.
The cheapest is the neck of silumin forming, which is usually only a covering rug coated with paint.
Processed eyes have the best appearance and higher costs.

With the same types of outer coatings of non-ferrous metal eyes are more expensive than the eyes of the black metal.
The appearance of the eye depends largely on the type and quality of the coating. And very often around the black metal with a lining it looks better than the color of the eye in a uncoated metal. Thus, the eyes of a brass eye "Gold" eye darkens over time, and the door made of steel coated with chrome, and then the titanium nitride ("gold") does not darken and actually create scratches are not affected.
The eye optics is divided into glass and plastic.
On the other hand, the optical glass is made of optical, "spectacular" and conventional glass.

If the properties of optical and glass bottles It is not widely distinguished, the lenses of ordinary glass are more fragile.
Plastic lenses are not afraid of shocks, but they have many important flaws: they are subject to scratches; Because of the electrolysis and the formation of static electricity, they attract dust to themselves, and finally most plastic materials Ultimately become yellow and lose transparency.

Practically the second - the third year of work with plastic optics, visibility in these eyes deteriorates.

3.5. Mirror deletion The lens lens lens performs the pin functions, and the door valve cannot be installed in the presence of a tick.
If, however, there is a light source behind the neck, it will be visible outside in the form of glowing points. This means that in this case the mirror lining does not fully implement the flap function.
Another defect in spray spray is a smaller aperture, the "mirror" of the eye, because

part of the light stream is reflected in spraying.
However, the door is a "mirror" in a simple requirement due to ease of use (there is no need to open and close the flap) and it is better to look.

3.6. I recieved it enlarge opening On the neck is allowed not to see it only with bad lighting, but allows the viewer to look into the eye of the door removed from it (up to 5-7 cm).

I do not need to bring eyes closer to eyepiece. At the same time, it retains excellent viewing power.
In the eyes of an enlarged lens lenses, the larger diameter lens is structured as a common eye and, therefore, a slightly larger body diameter of the eye.

Emission protection Tempets outside are equipped with most made grids. There is only a few cheap eyes.
A constructive solution for such protection can be very diverse, but the most efficient way is to install different holders on the outer eyes.

Doors for special purposes.
Sustainable doors Eyes ensure the protection of the observer weapon with short pipes. These eyes are tested for protection from the following weapons: "Nagan" TT "Makarov". The observer is also the eye periscovers, which are made on the principle of periscope and submarines, the eyepieces and lenses of which are not coaxial. Because a shot outside the lens sphere passes by the head of the observer.
Window doors can be equipped with bulletproof eyes and periscopes.
Currently, secret eyes are created, the design of which was developed in the middle of the last century by special services different countries For secret observation.

The design of these eyes is very different, but general feature - A wide view and very small diameter (from 0.5 to 0.8 mm) external lenses. The body of the eye usually has a pencil form and is located in the wall (or in the door). At the tip of "Pencil" is a lens, which looks at the outer surface level hidden in the background image.

On a surface wooden doors The lens is masked under the head of the nail with a diameter of about 1 mm. In this case, as a rule, a series of real nails with similar heads are stuffed.
Eyes for double doors They are designed so that they can be observed immediately through two doors (inside and outside) with a regular eye on the exterior doors and on domestic doorswhich are opposites attached to the optical device by ocular.

The Optical Block + Infantry system allows you to view the room for outdoor doors without opening the door.
There is also the demand for the door of a large diameter to 50 mm ( "Door-panoramic device") In which, instead of eyepiece, a lubricated glass is used.

On this glass, as well as on the screen, the image is oriented, which allows you to remotely view without approaching the door.

4. Door eye manufacturers

In our country and abroad, the main manufacturers of the door neck of the Opto-mechanical device and the factory for the production of accurate mechanics.

Production and installation of standard cells are often treated with small enterprises buying optical devices with optical devices.
In the Russian market, sales of doors: Russia, Belarus, China and Spain are widely sold out.
Russia produces the widest range of neck eye (up to 100 objects).
Russian plants produce only standard eyes (Vologda, Novosibirsk, Cheboksary, Krasnogorsk, Azov, Moscow, etc.).

Total about 20 items. These eyes are usually equipped with glass optics, but they have no good design and price losses, as in the eyes of Belarus and China.
Belarus has more narrow choice Eye than Russia, but in the production of standard cells occupies the leading position, produces glasses with a good design ratio and price. The production of glasses is concentrated in the cities of Minsk, Vileyka, Lida and Gomel.
China produces a very wide range of cervical eyes, but only the cheapest low quality glasses are transported to Russia, as a rule, with plastic optics and without dampers.

In addition, lenses are often incorrectly attached to the body with glue. The share of marriage between Chinese eyes is significant.
Spain in the Russian market was the doors, especially Amig products, which produce standard and oblong eyes with good design and at high prices, but often with plastic optics. Brass eyes of this company do not have protective coating And ultimately darkened.

Entrance doors providing highest level Safety, heat and noisy isolation, have one of the shortcomings: it is impossible to determine who is behind the door without opening. And this is exactly what I want to avoid. You can solve the problem by setting the door strip with a special glass cartridge or installing the housing.

Choose ridges

The last decision is much easier to implement.

Design Neck

The first prototype device served as an observation slot that crossed the door.

The clearance was closed by the latch, and the window broke down several times. It's amazing that it is difficult to imagine such a design in modern housing or the house that an alternative to the upper observation slot existed before the beginning of the 20th century.

The starting point was the creation special lenses "Fish eye" developed by American scientist Robert Wood.

A feature of this is the transfer of an extended image of an external object by the observer.

Modern design is as follows: The housing is plastic or metal, contains at least the eyepiece - observation benefits and purpose. On the case there are fixators, due to which the eye cannot unscrew the outside. The internal device is often equipped with a slider. Instead of the latter, you can use a mirror coating to prevent the passage of light through the eyepieces so that the visitor does not know whether they are watching or not.

The optimal viewing angle is 180-200 degrees.

In the first case, you get an image with a slightly blurred edges. More than to watch, without this lack. But the diameter of the device simultaneously increases. In the photo, the door is equipped with a small eye.

materials

The device of the device is made of plastic or metal.

Another option is more suitable for steel structures or massive wood.

Lenses for the device are made of plastic or glass.

In the case of highly reliable input designs, it is recommended to use the eye with an additional cartridge from the armored glass.

The material is able to move the direct hit of the ball from the gun (short trunk).

Special types of neck eye

Video shows various types of tools: panoramic, periscope, hidden, as well as camcorders.

Door with video camera

Modern and expensive device type.

The diameter of the housing is standard, so it can be replaced instead of an ordinary device.

Door in the front door

At the same time, the new device is equipped wide-angle chamber - Color or black and white, which transmits a complete picture to a monitor or TV. Eye with a camcorder, as a rule, is also equipped with its own monitor for monitoring.

The camera transmits the visitor image in real time, and if the owner of the apartment is missing, write down the date and time of the visit, which allows you to accurately determine who visited the house and when. Since the device with the camcorder reacts to traffic, it is registered not only by the guests themselves, but also by all visitors who crossed the landing.

Eye camera can be successfully used for organization own system security. In the photo - an example of a device with a video camera.

How to install door peephole with your own hands - eye review and video advice

To date, it is very dangerous to open the door, without seeing a person on the other side. Of course, to hear a familiar voice well, but as they say it is better to see once than ten times to hear.

Based on this, it can be said that the door eye is just a need. The cost of such a device may be different, but accessible to everyone.

Preparation Door to Eye Installation

Each owner of his home can carry out the installation of the door eye.

Subject: How to install the door eye?

Door eyes may vary with dimensions, construction, price. You can prefer any eye to the main thing that the installation dimensions fit the thickness of the linen of the inlet door. Although, most often, door optical instruments may vary widely.

Announcement: How to Install Door Print

By the way, it is best to give preference to the eye, which has a field of view of 170 ° and more, the devices of such a plan are called wide-angle.

In this case, the "guest" will not be able to nourish the wall and hide from you. In addition, it is better if the outer lens eye will be made of glass, as the plastic is scratched and less durable.

Installation of door eye

In order not to spoil the veneer of the door leaf when marking stands on outdoor side, At the necessary height, glue the paper strip, you can use a painting tape.

On the strip in any way convenient for you, it is necessary to note the location of the center of the opening of the eyes. Measure the planting diameter of the optical device, in the part with the internal thread. Next, select the required diameter drill, it should be more than 0.3 millimeters, ideally use corkscrew or screw. You can use a small mirror, you need to attach it to the door of the door, with the slightest deviation of the drill you will immediately see.

Announcement: how do you align the door threshold

Door canvas drill not throughout, and so that the guide center of the tool used is outward.

Continue drilling on the other hand, it will avoid veneer pumps on the front side of the door. Eye to develop into two parts, insert the first part with the outer thread from the outside of the door web, insert the second part of the eye, respectively, from the inside of the door, twist the part. Tighten your eyes to do this, use the slots on the inner frame of the device. In order not to break the screwdriver, it is necessary that the sting of the tool is in both slots.

You can use a suitable thickness of the steel plate. On this installation of the door optical device is completed.
