Performance characteristics of IP network intercom system

Also known as IP network video intercom system, IP network intercom system, IP network internal intercom system, is an intercom system based on network transmission.
IP network video intercom system (NLS series) is mainly used in: family personal communication, enterprise group communication, office, shopping mall, ATM automatic teller machine, vault, self-service bank, parking lot, toll station, school, factory, hotel, etc. Network and need to call and intercom place at any time.
Performance characteristics of IP network intercom system
1. The sound quality is clear and smooth, free from the interference of external electromagnetic waves, client alarm voice prompt, voice and video synchronization recording, alarm information query function, alarm terminal location information display, etc.!
2. The transmission distance is infinitely extended. Intercom can be realized where there is a network, and a wider range of information communication system can be constructed!
3. Using digital audio processing technology, echo suppression, can achieve high-definition video and voice!
4. Confidential call, special audio coding format, with encryption processing, to prevent qie listening!
5. It is easy to adjust the communication scale, and the system can be expanded by adding terminals!
Six, personalized electronic map function!
