The characteristics and advantages of building intercom system networking

The characteristics and advantages of building intercom visual system based on network technology are as follows:

Fast transmission speed: The transmission speed of the local area network can now reach 100 megabytes to the desktop. If the optical fiber is used to the desktop, it can reach the gigabit bandwidth, which is not possible by the bus system technology;

Digitization: The application of TCP/IP networking technology in intelligent community is a revolution of the entire intelligent community technology, which processes voice, data and images in digital technology. Therefore, the equipment of the entire community is a digital product;

The transmission line is simple, and the networking is convenient: since the sound, the data and the image are digital signals, the network connection line of the entire community only needs one cell LAN, and real network networking is realized;

With online inspection function. Since the system uses the standard TCP/IP communication protocol, each device on the network has a fixed IP address, and its powerful data processing capability can detect the online condition of the online device in real time;

Realize multi-channel function of the cell. After the cell adopts TCP/IP networking, its powerful data processing capability and hundreds of megabytes of bandwidth make the implementation of multi-channel in the cell very simple. Even if there are many door hosts simultaneously, there will be no channel blockage and busy. ;

The wiring cost is low. Because a network cable can solve the problem of system networking, on the basis of this platform, it can also share the same line with network closed-circuit monitoring, perimeter prevention, networked parking and other systems without rewiring, so it is better than Traditional analog bus costs are much lower;

With online patrol function. The non-contact card access control system provided by the door host can realize the online patrol function, that is, the card reader of the door host can be used as a patrol point, and real-time online patrol can be realized.

Based on the above technical characteristics, therefore, the smart home developed on the basis of it has powerful functions:

Network video intercom function: each resident in the apartment can see the visitor's image through their respective terminal screens, talk to them, and control unlocking;

Internal telephone function: any two indoor terminals in the system can talk to each other, the terminal can actively call the extension, just like the internal telephone, does not generate any telephone charges, and can also contact the security management center;

Powerful security function: The security management center can receive calls and alarm signals from community residents. The security management center is equipped with corresponding software. When there is an alarm event, the software automatically pops up the alarm prompt interface to display the alarm category and household number. You can browse various historical records such as alarms, calls, and access control. The mobile phone of the household can also receive alarm information. The user can control and operate through the telephone and Internet network. The function is very powerful.
