Nitek VB31M Video Balun for UTP Category Cables

The VB31M is a UTP video balun transceiver that serves as a UTP video transmission device converting coaxial signals for twisted pair transmission into UTP signals. The VB31M provides a low cost means of sending live video over UTP point-to-point wiring for distances of up to 750 feet (225 meters). The VB31M video balun transceiver operates with other passive CCTV baluns or active video receivers to provide CCTV transmission. Up to 1,500 feet (450 meters) with the TR515 single channel receiver and model 51 series hubs, and up to 3,000 feet (900 meters) with the TR560 single channel receiver and model 56 series hubs. A basic system uses (2) video balun transceivers, one at each end of a twisted pair of wires. These units are intended for use over existing in-house telephone wiring, Category 5 wiring or other twisted pair cable runs to provide a convenient, cost-effective alternative to coax. The VB31M is designed to provide superior immunity from noise and interference even when running next to line power. The VB31M is a UTP transceiver that provides another Security Transmission Solution from Nitek.
