Application of IP network video intercom system

September 27, 2022
The video intercom system is based on network transmission. Some manufacturers develop high-reliability technologies for special applications such as prisons and finance. There are 30/60/90/120/300/600 IP network video intercom hosts. IP network dial-up video intercom host and IP network paging video intercom host; in addition to paging host, other hosts have desktop and embedded models for you to choose, and use 10.2 inch digital true color touch screen, The low-light CMOS color camera is placed above the color screen and the angle is adjustable. The cable interfaces of the host are all located directly above, from left to right, the DC14V power interface, the external device interface, and the network interface. The external device includes an RS-485 bus port, which can be connected with an LCD screen or a mobile phone SMS transponder. .

In order to meet the application needs of different places, some manufacturers have developed and designed a variety of intercom extensions, such as ordinary type, metal anti-riot type, industrial-grade anti-riot type, anti-riot waterproof type, etc., the common type intercom extension adopts plastic shell, which can be applied to The anti-riot type intercom is an aluminum alloy panel with anti-demolition and anti-violence functions. It is suitable for places where violent incidents such as prisons are prone to occur. Intercom extensions vary in appearance, interface, etc., but basically cover network interfaces, power interfaces, and external device interfaces. Among them, the external device interface can be connected with alarm/release button, microphone, speaker, active speaker, tri-color door light, alarm linkage equipment and other auxiliary equipment, and can also be connected with magnetic or electronic control lock to realize door opening prompt, single The intercom extension can control two pairs of door magnets or two lock switches. In addition to ordinary extensions, the surveillance extensions use a low-light CMOS color camera for easy voice/video communication between the two parties.

All devices of the system are transmitted over the network, circumventing the situation where the signal is susceptible to interference during analog transmission. The system achieves good network optimization through IP. The system can be configured with up to 600 IP network management hosts and more than 70,000 IP network extensions. Because the system supports a large amount of devices, the IP address box is required to manage the IP addresses of all devices. Before the device communicates, the device needs to access the address box to obtain the IP address of the device to be communicated. The video intercom host has an automatic IP address backup function, which can back up the IP of all devices stored in the address box to the host. When the address box fails and cannot provide IP address query service for the system, the system can also access the backup. The IP address file in the intercom host enables unobstructed communication. Among them, the video intercom host can query and set the IP of the machine and the IP address box. The IP address setting of each intercom extension needs to be connected to the PC to be set up on the PC. If an IP conflict occurs, the system will be in the system. Prompt in the host interface.

A wide range of IP network video intercom systems. It can effectively prevent system crashes, virus intrusion and other problems; and support MP3, G711 (16K) audio codec mode, solve the echo and howling during network intercom, the system constantly makes sounds throughout the test, but They are all clean and clear, and there are no abnormalities such as harsh sounds.

With the development of the economy and the reality that there are fewer people in China, the community community is the realistic choice of the national conditions. Under this situation, the unit non-visual video intercom, networked non-visual intercom system, CRT Black and white video intercom system, color TFT screen video intercom system, security video intercom system, semi-digital networked video intercom system and digital building video intercom system. Intelligent products have created a new era of digital homes around the world. But in fact, this system is still in the stage of centralized control of household appliances, from a truly intelligent home life, energy-saving and environmentally friendly home life, there is no small distance.
