VB37F Nitek Video Balun Transceivers for Twisted Pair up to 750 feet (228 meters) w/ Female BNC

Video balun transceivers for twisted pair up to 750 feet (228 meters). Two types are available. The basic VB37 model and the VB39 with built-in surge suppression for added equipment protection.

The video balun transceiver is a video transmission device that provides a low cost means of sending live video over unshielded twisted pair, point-to-point wiring for distances of up to 750 feet (228 meters). The VB37 and VB39 are compatible with all of the "up-thecoax" control systems. A basic system uses (2) VB37 or (2) VB39 units, 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, costeffective alternative to coax. The VB37 and VB39 are designed to provide superior immunity from noise and interference even when running next to line power!
