The VB37M is a high noise immunity passive UTP Video balun for twisted pair transmission of CCTV video. The VB37M is a “heavy duty' design with two screw terminals for UTP connection and a female BNC for coax connection. This passive UTP video balun operates with other passive video baluns, transceivers or active receivers.The VB37 series is available in the M model (male BNC) and the F model (female BNC). The VB37M UTP 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 VB37M 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 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 VB37 series units are designed to provide superior immunity from noise and interference even when running next to line power.The VB37F alaso provides a convenient mounting tab for installation. The VB37F is a UTP transceiver that provides another Security Transmission Solution from Nitek.
