At present, in the intelligent system used to transform residential communities and real estate developers, according to statistics, the building intercom system is currently the most frequently used, the building intercom is the main credential for the entrance and exit of residential units, and the head of the household conducts identities for visitors. An important channel for confirmation and release is that it is equipped with an access control system and a video intercom system, with dual identities of access control and video intercom.
There are many forms of identity authentication for the door machine. Different control methods can be implemented by adding different access control modules. At present, there are mainly credit cards or password authentication. According to the introduction of South Technology, face recognition is the current mainstream. Intercom, it is mainly in the original features of the entire video intercom, one of the biological recognition facial recognition technology applied in the video intercom system. Through the collection of face photos of the heads of household in the community, they are entered into the system. The head of household enters and exits the building unit, the entrance of the community, etc., will automatically match the database face information and identify the door open.
Building visual intercom system is a set of multi-faceted application system, in addition to point-to-point, but also to point-to-multipoint, linkage function.
Peer-to-peer: The first is the docking of the tenant with the door machine or the management center. When a guest visits, the occupant must be able to communicate with the door phone through the indoor unit. At the same time, the user can see the image from the door machine, so that the owner can confirm the identity of the visitor from the voice and the image, and then through the control button of the indoor unit Open the door. The indoor unit also needs to maintain a smooth transmission with the management center. When the management center has a message to be released, the owner can be informed via SMS or voice.
Point-to-multipoint: that is, the communication between the household and the user. Neighbors should always contact each other. It is inconvenient to run upstairs and downstairs. They can communicate through the building's visual intercom system. However, in actual systems that are actually put into use, there are not many such functions. Some international security companies are introducing corresponding technology products according to the needs of the domestic market, such as the newly developed NY pure digital system implementable by Fermax. The intercom function between households, the use of the system is based on the premise that one party needs to send an invitation through the video intercom system on the phone via SMS, and the other party can call and intercom only after accepting the invitation.
Control the elevator: Through the linkage between the building intercom system and the elevator, it can also realize the function of controlling the elevator. When the database is established, information such as the name of the owner, residential unit, room number, etc. will be entered in the system. After the visual intercom system completes the identification of the occupants, the owner information is sent to the elevator control system and the owner enters the elevator. After that, the elevator will automatically reach the floor where the owner is located. For the visitors, when the system receives the permission of the owner to enter the system, the elevator will be linked and the automatic visitors will be sent to the floor of the head of the household. According to the introduction of South Billion Technology, using this method will bring inconvenience to unwitting card holders or chain gate users. Although it is more troublesome, it increases the level of security and effectively prevents illegal personnel from entering and inciting. At present, the application of building visual intercom system and elevator linkage in the community is not very much, although it can improve the security, but in the application of human nature, it is still greater than the benefits.
In the intelligent community security system, the safe, fast, and comfortable life is still the needs of the residents in the community. Of course, today's technological progress, building intercom manufacturers should develop a better, more representative intelligent system.
