3. The design adopts embedded computer technology and DSP audio processing technology.
4. Built-in 1 channel network hardware audio decoding module, support TCP/IP, UDP protocol, realize network transmission of 16-bit CD audio signal quality.
5. Compatible with router, switch, bridge gateway, Modem, Internet, 2G, 3G, 4G and other arbitrary network structure.
6. Support full duplex two-way intercom function, with network echo cancellation module; IP terminals to achieve two-way intercom, the delay is less than 100ms; At the same time, the network echo roar was completely suppressed.
7. Support help signal bell, flashing light prompt, one button to accept help, intercom function, but also can support hands-free call and receive broadcast, to achieve fast link.
8. Support a variety of call strategies, including call waiting, call forwarding, and no one listening reminder.
9. Support automatic answering, manual answering, support custom answering prompt tone.
10. Support transfer time, unanswered time, call waiting time customization.
11. Built-in 3W full frequency high-fidelity speaker, to achieve two-way call and network monitoring.
12. A φ3.5 headphone socket and a φ3.5MIC input socket match 95% of headphones and portable microphones on the market.
13. One way audio line output, external expansion power amplifier; One way audio line input, provide multiple audio source transmission.
14. One way alarm triggers short circuit output, cascading out alarm equipment or access control; All the way short circuit input, can be used to trigger preset voice prompt (or alarm), can also be used to control access control linkage input short circuit signal.
15. Digital products, easy to expand capacity, not limited by geographical location, no need to add room management equipment, using the design concept of common network free line construction, easy to install.
16. Support the broadcast system to upgrade the firmware remotely to the terminal, no need to upgrade locally to the terminal, and reduce the work intensity of maintenance personnel.
