双绞线视频传输器（双绞线视频收发器）是利用五类网络线缆代替同轴电缆，不仅解决了安防和视频广告工程中普通视频电缆存在的远距离传输信号严重失真和在复杂工业环境下的电磁视频干扰问题，而且大大节约了线路建设成本，施工和维护也变得十分简便，成为视频监控工程在解决1-3公里中长距离传输问题上的一种最为经济实用的办法。
Twisted pair video transmitter ( UTP Video Transceiver ) is the use of five kinds of network cable instead of coaxial cable, not only solve the security and video advertising works in ordinary video cables exist serious distortion and remote transmission signal in complex industrial environment electromagnetic video interference problems, but also greatly save the line construction cost, construction and maintenance becomes is very simple, as video surveillance project in the solution of 1-3 km long distance transmission problem is one of the most economic and practical way.
