双绞线视频传输概述

传统的同轴电缆和光纤传输方式解决了近距离和远距离的视频传输问题,100-2000米左右的视频图像信号传输成为监控领域的瓶颈。双绞线视频传输设备,使用价格便宜、取材方便的五类或五类以上的非屏蔽双绞线(UTP计算机网线)四对线中的一对线传输一路高质量的视频信号,其余双绞线线对可以用来传输音频信号或控制云台的RS-485数据等,也可以传输更多的视频信号,而且信号之间互不干扰,传输距离0~2000米可选。双绞线视频传输设备具有超强的干扰抑制能力,对于干扰较大的环境,比如在电梯、水泥厂、钢厂、电厂等强电磁干扰环境,都可以很好的使用。使用这种传输方式,具有布线方便、设备安装简单、可靠性高、抗干扰能力强、传输效果好、系统成本低廉等许多优点。双绞线传输设备的使用改变了智能大厦、智能小区以及各种监控场所的传统布线方式,为监控工程系统设计提供一种高性价比的解决方案。

UST104T Quad Channel Active UTP CAT5 Video Transmitter
1000-4000ft  Lightning Surge Protection / Figure Enhanced Model

Introduction
UST104T UTP CAT5 Video Transmitter is an active (amplified) device that allows the extension of real-time monochrome or color video on up to 4000ft ,using Category-5 Unshielded Twisted-Pair (UTP) CAT5 networking wire. Baseband (composite, PAL/NTSC/SECAM) signals of any type are supported.

The unparalleled interference rejection and low emissions of the Model UST104T & UST104R allows long run video signals to co-exist in the same wire bundle as telephone, datacom, or low-voltage power circuits. This allows the use of shared or existing cable plant. Ground-lifting ensures no annoying "hum-bars" when ground potential differences exist. With built-in lightning protection,transient protection, ESD protection,damaging voltage spike problems are eliminated.
