1) Installation: metal shell housing design, the host adopts the tail-end line design;
2) Wiring: 1 host connected to 1 extension, the host and the extension should have digital full-duplex high-definition intercom, effectively preventing whistling and channel interference;
3) Remote intercom monitoring: the host can realize remote emergency alarm calling and being called, and the host and extensions can conduct two-way intercom with the IP network intercom command and control console in the monitoring center, and the IP network intercom command and control console can listen to the window intercom host and extensions in real time;
4) Remote broadcasting: The IP network intercom command and control console of the monitoring center can broadcast real-time notification to the main unit and extensions of the window intercom;
5) operation prompts: the equipment should be easy to operate, with light or sound signal prompts;
6) volume adjustment: the host has a key tuning function to facilitate the operator to adjust the host and the extension of the volume of the intercom with a key;
7) Remote management: the system should have remote management, remote configuration of the relevant parameters, easy maintenance, while supporting remote online upgrade.
8) Network communication protocols: TCP, UDP, ARP, ICMP, IGMP, HTTP, FTP.
9) Audio coding: MP2/MP3/PCM/ADPCM
10) audio sampling, bit rate: 8kHz-44.1kHz, 16bit, 8kbps-320kbps
11) Network Interface: 1 RJ45 interface with 10/100Mbps transmission rate and 1 extension interface;
12) Operating temperature and humidity 0 ℃ ~ 50 ℃, ≤ 90% RH (no condensation)
