Door panel for video intercom

Video intercom is a very popular in our time home security monitoring system. With it, you can both limit access to undesirable visitors, and to facilitate the owner of the process of opening the door. With this intercom, you do not need to ask through the door "Who's there?" Or rush into the yard to open the gate . Unlike an audio door phone, a modern device with a video camera allows you to see and even take pictures of a person coming to you. Video intercoms are used in multi-family and private homes, offices and industrial buildings. Thanks to their convenience, they are common today.

The principle of the door panel for a video intercom

As a rule, the calling panel consists of several components, each of which performs a certain function. This is a call button, an intercom with a microphone and a speakerphone, a built-in video camera and an electric lock opening system. All these components are located on a compact panel, which is usually installed on the entrance door or wicket door.

The calling panel works as follows:

• the visitor presses the button;
• on the monitor installed in the hallway of the apartment or at home, an image from the camera appears, and at the same time a signal sounds, warning about the arrival of the guest;
• the host communicates with the guest through video and audio communication, and then opens the door by pressing the electric lock button. In this case, the owner sees and hears the guest, and the latter, in turn, only hears the voice of the owner of the house;
• if you decide not to give out your presence, just do not "hang up" the video intercom, and the guest will leave in full confidence that you are not at home.

So, the panels are different, and they differ not only in value. Here are a few basic criteria for choosing a street calling panel for a video intercom:

1. Calling panels come with a black-and-white or color picture. The first, as a rule, is cheaper, but this parameter does not affect the recognition of the visitor - a black and white picture is no less clear and understandable than that offered by color calling panels for video intercoms.
2. Depending on the features of the installation panels are mortise or invoices.
3. The calling panel can be designed for several subscribers. In an apartment building or office building with many offices, the call button replaces the keypad.
4. The video camera on the calling panel can have a different resolution (usually from 350 to 900 TV lines). The higher the resolution, the better the image. In addition, good cameras automatically adjust to the level of lighting on the street or in the dark vestibule, and some also have a night vision function.
5. The wireless calling panel for the video intercom today is at the peak of popularity. With it, there is no need to lay cables, ruining the finishing of walls in a house that has already been built. However, you should be aware that wireless equipment is only compatible with a digital IP calling panel.
6. The color scheme of the devices is very wide and depends, as a rule, on the design of the entrance door / gate.
7. Video intercom can be equipped with additional functions. Nowadays, the calling panel for a video intercom with motion sensor, fingerprint reader, etc. is very popular. And some models of video intercoms allow not only to see the visitor, but also to take a photo or record a video of your conversation.
8. Sometimes the calling panels have illumination, which helps the guest in the dark to find out where the "bell" is.
9. Usually manufacturers protect the calling panel, equipping it with an anti-vandal grille. And from the rain the video intercom device will protect the visor.
