Impedance 100 Ohms +/- 20% UTP Category 2 or better The VB31PT UTP video balun transceiver is a passive device with pigtail coax and a male BNC for twisted pair CCTV video transmission operating with either other passive video baluns, transceivers or active receivers. The VB31PT UTP video balun transceiver provides a low cost means of sending live video over unshielded twisted pair, point-to-point wiring for distances of up to 750 feet (225 meters) with other CCTV balun transceivers, 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. The VB31PT is compatible with all the ''up-the-coax'' control systems. A basic system uses (2) video balun transceivers, one at each end of a twisted pair of wires. These UTP Video Products 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 VB31PT provides superior noise and interference immunity even when running next to line power. This UTP transceiver provides another Security Transmission Solution from Nitek.
