IP Telephone Intercom Systems Description


WIFI Intercom Systems Description

KNTECH Wifi Intercom Systems BASIS SIP intercom and broadcast system is a new generation of voice

broadcasting system, which is based on internationally accepted standards IP and SIP communication

protocol and developed on the basis of Kntech matured carrier-grade VOIP product.

This system has following advantages: First, it solves problems such as distance restriction, susceptible

to interference,large investment in equipment and higher maintenance costs in conventional analog

broadcast system transmission; Second, it also solves problems such as nonstandard broadcast protocol,

weak intelligence, poor service application,difficult to connect with telephone network etc in traditional IP

digital broadcast intercom system. Third, it really realize integration of computer network,digital video

surveillance and interior communication.

Simply connect system terminal to LAN or international internet, without re-wiring, and you can quickly

build IP emergency and public broadcasting system.

The Most Striking Features

     It is cost-effective with short construction period, easy expansion, and low maintenance costs.

Meanwhile, the system can also add interfaces of system software&hardware based on customer’s

requirements, linking with fire alarms, access control systems and video surveillance systems.


     It can be widely used in subway, highways, power plants, gas stations, mines, schools, hospitals, banks,

prisons, urban,key monitoring targets and military administrative zones and many other industries and

Various intercom,broadcast technology comparison

•Traditional IP digital intercom broadcast compare with SIP intercom broadcast:



①Protocol compatibility: support SIP 2.0(RFC3261) and relevant RFC protocol,telecom operators IMS

criterion;besides,it is also compatible with peer-to-peer communication protocol;

②Conversation landed:it can be realize voice landed through IPPBX or IMS platform(talk with PSTN fixed

telephone,GSM telephone,CDMA mobile phone etc);

③ HD voice quality: meet telco grade electroacoustic standard requirement(TIA-EIA-920、TIA-EIA-810A);

④multi party call: support three-way calling or multi party calling;support meeting.

SIP Intercom and Broadcast System Features
