RACK MOUNTED VIDEO TRANSCEIVERS FOR TWISTED PAIRS USING BALUN BALUNS TO TRANSMIT THE VIDEO SIGNAL OVER TWISTED PAIR WIRE CABLE

rack mounted balun hubs in 9 and 18 inputs

A balun is a passive, non-amplified device which allows video signals to be transmitted over unshielded twisted pair, UTP, telephone cable. This means of video transmission provides significant savings when compared to traditional coax cable.

Using twisted pairs will bring cost savings in several ways. Twisted pairs are less expensive than coaxial wire cable. It may also be possible to use previously installed telephone cables with unused pairs..

TWR-9S & TWR-18S: Surge Protected Models

 

The TWR series provides a convenient rack-mounted

solution for multiple camera installations using baluns to

transmit the video signal over twisted pair cable. The

TWR-9 has 9 balun inputs, while the TWR-18 has 18.

 

Each input consists of a special type of transformer which converts the video signal to a 75 Ohms unbalanced output which can be connected to a coaxial cable compatible with the input of any monitor, VCR or multiplexer.

Due to the excellent balance provided by the TWR series the video signal will not affect or be affected by other signals, even when they are transmitted in contiguous pairs. You can transmit data, telephone signals or low voltage power using neighboring pairs without affecting video signal quality. Most of the electrical noise and RF interference which affect coaxial cables are eliminated by the TWR series.

 

The UTP CAT5E wire cable, widely used in computer local area networks, LANS, allows you to send signals from 4 camera up to 2,000 feet [600 meters]. In addition to reduced cost, it is easier t achieve a neat installation compared to conventional CCTV installations with coaxial wire cable. Also, splicing is much cheaper and faster compared to a properly installed coaxial joint.
