Overview
 

It adopts modularization function box design; each video transceiver can transmit 2 channels uncompressed digital video. There are three 5-pin ports, or two 5-pin ports and one RJ45 Ethernet port on each transceiver. Each 5 pin port can be configured as 1～2 channels RS-232/485/422 data port,2 channels bi-directional audio port,2 channels unilateral contact closure port or 2 channels TIL signal port. Ethernet can supply 10M or 100M wire speed, with 10/100M port adaptable.

 

Video transceivers can independently form a single/multi mode optical transceiver and be configured 1～2 piece audio/data extended board, transmitting multi-channel audio, data and contact closure signals. It support to be configured a management plug, to implement network management function.

 

It is now widely used in security monitoring and control system, highway, Traffic Control Photographic System, automation and intelligent residence.
