The characteristics of the residential community are user concentration, large capacity, and unified security management. Although there are various security systems on the market, there are not many products that truly meet the characteristics of the community and are suitable for residential use. As such a product, the building intercom system has such features as having less connection, no isolation of households from short circuits, no indoor power supply, no power consumption in standby state, no special video line, high stability, reliable performance, and easy maintenance.

With the continuous increase of residential housing, property management in the community becomes increasingly important. The management methods of visitor registration and watchkeeping are not suitable for the fast, convenient and safe requirements of modern management. The building intercom system is equipped with anti-theft doors at each unit's mouth. The administrator of the community master control center, the intercom host at the entrance and exit of the building, the electronic control lock, the door closer and the visual intercom extension at the user's home are formed through a dedicated network. In order to realize the intercommunion between the visitor and the tenant, the tenant can remotely open the anti-theft door, and each unit ladder visitor can then call the tenant through the intercom host, and the other side can enter the building without permission, thereby limiting the entry of illegal persons. At the same time, if the occupants are robbed or have a sudden illness at home, the security personnel can be notified through this system to receive timely support and processing.

How is the extension of the building intercom system installed?

The building intercom is mainly fixed by screws on the base of the extension or fixedly installed on the backboard and the wall.

A wall-mounted extension: The extension installation method is surface mounted. However, the extension itself has more walls and the visual results are not good. Due to the limitation of its own volume, many function modules cannot be loaded inside the video intercom (some loaded function modules are simplified modules).

B. Embedded extension: The installation method of the extension is concealed. First, the embedded bottom box of the extension is installed on the wall, and then the extension is fixed on the embedded bottom box. After the embedded extension is installed, the basic height of the wall is the same, and the video intercom is very good for the overall visual performance of the interior. In addition, because the embedded installation extension has a relatively large space, it can load more expansion effects; its disadvantage is that it needs to be buried in the bottom box, the construction is relatively difficult, and it is not easy to move after installation;

C color video extension: ultra-thin wall extension: due to the advantages and disadvantages of the above two extensions, such extensions are thinner than traditional wall-mounted extensions (traditional wall-mounted extensions use a handset design, and the visible part is required to be compatible with black and white Display screen, so beyond the wall height is generally more than 40MM, the basic thickness can not be reduced.) New wall-mounted extensions generally use hands-free calling technology, the visible part of the color LCD display.
