CCTV 4-channel managed digital video optical converter

Overview

It adopts modularization function box design; each video transceiver can transmit 4 channels non-condensing 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 12 channels RS-232/485/422 data port2 channels bi-directional audio port2 channels unilateral switch value port or 2 channels TIL signal port. Ethernet can supply 10M or 100M wire speed, with 10/100M port adaptable.

It is now widely used in security monitoring and control systemhighwayTraffic Control Photographic Systemautomation and intelligent residence.
