Wireless video door on the door

The need for security is one of the basic human needs. It is especially important to feel protected at home. To implement it, people used various measures: from primitive fences to modern video surveillance devices. Every day, high technologies are increasingly entering the lives of ordinary citizens, and today no one is surprised at the camera looking out of the door.

Such an overview device allows you to control the staircase or the area in front of the house, record what is happening in video and photo format, and also store this data in the device’s memory or on external media. According to the signal transmission method, video peephole models are either wired or stationary (the monitor is mounted directly on the wall next to the door and connected to the camera with a cable) and wireless (the radio signal is transmitted to the monitor).

There are several types of all wireless video eyes models. Black and white frameless eyes are placed in a truncated body. Video recording is carried out by the built-in CCD (CCD), and for illumination it is necessary to additionally purchase an infrared LED. Such video eyes differ from ordinary ones and require additional installation of a special cap.

Other variants of video eyes, recording in the black and white spectrum, are equipped with a shell and are made in the form of a familiar eye. These models are easy to install in a familiar hole. The following type - eyes in the shell, leading color recording. These models can be square, mounted on a tripod, or ordinary, installed in the door in the place of the peephole.

In the design of the peephole distinguish the outer panel and indoor unit. The outer panel is located on the door, and the unit with the monitor is mounted in any convenient place. Most often it is placed near the door at the level of a person’s eyes (160-170 cm). The outer panel is made from an alloy of anti-vandal strength. Also for video peepholes used on the street, they place special demands on the temperature range.Such a peephole must withstand a temperature difference of -30 to +50 degrees.

Cameras in such devices most often use color, small-sized with a matrix from 0.3 to 2 MP. This allows you to clearly see the person behind the door. It is also possible to install a lens with a wide angle of image capture on the camera, allowing you to see the entire landing. The outer part of the peephole is equipped with a call button, which gives a signal to the inside of the apartment and allows you to talk to the visitor, without opening the door, through the built-in microphone. Illumination, working in the infrared spectrum, allows you to see what is happening behind the door, even in complete darkness. The radius of the backlight is 1.5-2 meters.

In many models of video peepholes there is a sensor that responds to movement. This is an additional and useful feature. The camera turns on only when movement appears in front of it. This can significantly reduce energy consumption. Inside the house is a unit with a monitor. It displays the image from the camera eye. Also, some models allow you to open the front door by pressing a few buttons onthe monitor.

All types of eyes can highlight both advantages and disadvantages.

Benefits:

• With all the features that such a device provides us, it has a relatively low price.
• Wireless device is much faster to mount than fixed wired.
• The monitor from the wireless device can be installed in almost any part of the house, which makes it possible to see the guest without being distracted from the main occupation.
• The video from the camera will ensure the safety not only of its owner, but also of all neighbors from the site, it can be provided for investigation in case of illegal actions.

Among the shortcomings are the following:

• Since the signal transmission occurs at radio frequencies, it is easy to drown out or add noise. This can occur both intentionally on the part of criminals, and as a result of the work of nearby conductive elements.
• If the peephole is not equipped with an anti-vandal body, it is easy to break.
• If the device does not provide mains power, the batteries will often have to be charged, especially during the cold season.
• Wireless video eyes can operate in a limited temperature range.

Before buying such an important component of security as a video door, you should consider several important nuances:

• First you need to determine the place of installation. If the peephole is located in the stairwell, then special means of protection from weather conditions are not needed. But the device for the street should be equipped with a rain canopy.
• Preference is better than the smaller model under other equal conditions.
• The model chosen for the street must withstand large fluctuations in temperature, at the entrance this criterion is less important.
• For installation on the street it is better to choose a large viewing angle (up to 180 degrees), for a room 90-120 degrees will suffice.
• Do not save and buy cheap Chinese models.

• The attention should be paid to the choice of the monitor. For people with poor eyesight, models up to 8 inches will not fit.
• Do not forget to measure the thickness of the door.
• Plus will be the availability of backup power.
• The need for infrared lighting will depend on the illumination on the staircase or the street in front of the house.
• Pay attention to the presence of an additional motion sensor in the selected model and its location.
• The price of the selected model and the comfort of its use depend on which picture (color or non-color) is transmitted to the monitor by the camera.

It is easy to install a door video peephole, but it is better to provide this work to professionals. Despite the huge selection of manufacturers and models, there are no fundamental differences in their installation.

The procedure is as follows:

• Measure the thickness of the door. This stage must be completed during the selection of the model. The thickness of the door and the length of the peephole should be the same.
• To pick up screws for fastening of a peephole of the corresponding diameter and length.
• Remove the old peephole.
• Install the camera. To do this, pass the external module through the corresponding hole and fix it with panels. Fasten the design with screws.
• Fasten the bracket to the door from the inside.
• Assembling video peepholes should be done as carefully as possible, without tightening the screws too much, because the device is very fragile.

Today in the market you can buy video eyes in a wide range of prices - from the most affordable to premium. The choice of a suitable option should be carried out, relying solely on their requests,since the presence of unnecessary additional options to you significantly increases its cost.
