This product is used to extend a video and stereo audio signal on Cat5 cable to over 2,000 ft. The video input can be Composite Video, or S-Video (both connectors are provided, but only one can be used at any given time).

The 100% isolated outputs mean that there is no ground connection between the monitors connected at the output and the video source at the input. This eliminates any ground-loop vi
