Characteristics of the Taichuan digital intercom system

    Flexible networking methods The transition from traditional buses to fully digital intercoms is a global technological trend, and fully digital products are revolutionary alternatives to visual intercoms. In the design of traditional bus based building Intercom Systems, whether using the "switch+matrix" or "switch+selector" approach, multiple factors such as the location of the community center, the direction of the weak current pipeline network, and the impact of strong current equipment must be considered.

    And adopting Powerful wireless communication function The TCP/IP   fully digital intercom system has powerful wireless communication capabilities, truly achieving "no wiring". The indoor unit can be connected to an external wireless AP and can be stored in any location on the wireless network without being limited by building layout. The indoor unit is designed with wireless communication for controlling household appliances, switches, sockets, etc. 2.2.4 Solving Remote Video Transmission

When traditional intercoms are used for video networking in residential areas, SYV75-5 video cables are generally used for video transmission within 500 meters, and SYV75-7 video cables are generally used for video transmission above 500 meters. But when the distance exceeds 1KM, the image is inevitably attenuated. And using TCP/Ip Intercom, data is shared on broadband, and the digital gateway within the networked devices adopts the most advanced algorithms and decoding technology for video compression and extraction. Even at long distances, the image quality is still clear.  

Avoid channel congestion

For large communities, traditional building intercom systems are generally divided into several small zones for management, with multiple entrances and exits, and equipped with multiple wall mounted machines or sub management machines. The bus system is a half duplex communication method, so when one of the wall mounted machines calls the management center, other wall mounted machines or sub management machines cannot avoid occupying the line. The network-based building intercom system, as it is connected to a broadband network and has a switch in the center, uses full duplex communication for real-time data exchange through multiple channels, which is not only simple and fast, but also effectively avoids busy lines.  

Reduce equipment and facilitate debugging

The traditional bus based building intercom system has numerous networking devices, such as switches, information storage devices, selectors, matrices, etc. When any device fails, it will increase the debugging workload, and such intermediate devices can only be provided by the manufacturer. Replacement depends on the manufacturer. The TCP/IP building intercom system follows the standard TCP/IP protocol, which eliminates the need for numerous intermediate devices such as switches and selectors in the intercom system, reduces system complexity, and facilitates debugging. For the local area network of TCP/IP intercom system, routers, switches, etc. are common products on the market, and configuration replacement is easy.  

Interface standards, specification standards, conducive to integration

Traditional bus based building intercom systems are often self wired and form independent network systems. Due to the lack of industry standards and difficulties in system integration, products from different manufacturers cannot be interconnected, and the visual intercom system is also difficult to interconnect with other weak electronic systems. But the TCP/IP intercom system can borrow the broadband network of the community, and multiple weak electronic systems can share the same broadband network. The cost of building a network is relatively low, and standard interfaces are used. After standardization, each subsystem can be integrated well, improving the practicality of the equipment.
