One of the functions of network surveillance cameras in video surveillance industry: What does the two-way network voice intercom function mean?

Using modern communication network, combined with network communication technology, adopting digital IP/TCP communication protocol based on network transmission and based on network digital audio technology, audio signals are transmitted in the form of data packets on local area network and wide area network. Coupled with ITC's unique core processing server and humanized operating hardware, a set of pure digital transmission network two-way intercom voice communication system is formed.

As a new generation of digital IP network two-way intercom voice communication system, it has advanced functions such as pure digital audio, two-way intercom, hands-free intercom, emergency call, remote call, music broadcast and emergency broadcast.

System functional characteristics

1, audio echo cancellation technology, which solves the echo and howling during network intercom. High-definition two-way visual intercom, MP3 for broadcasting and 32K audio sampling for calling.

2. It can be transmitted in local area network LAN and wide area network WAN (which can cross network segments and routes) to realize long-distance calls around the world.

3. Embedded architecture can prevent problems such as "system crash" and "virus invasion".

4. Adopt 10.2 inch digital true color screen, low illumination CMOS color camera, linux operating system, Chinese display interface and intelligent full touch operation. It can realize two-way visual intercom, monitoring, broadcasting, audio and video recording and other functions.

5, there is a call security function.

6, zero phone bill. Transmission through the network, during the call, neither party will generate fees.

7, simple installation, equipped with RJ45 standard network cable, plug and play.
