D Video Balun Transceiver for TVI/CVI/AHD
Product Description
The HD VB31PT video balun transceiver has been designed to meet the needs of the HD TVI/CVI/AHD cameras. It 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 up to 225 meters or 750 feet with any other Nitek passive balun transceivers. The HD VB31PT is also compatible with all standard definition CCTV and any of 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 HD VB31PT is designed to provide superior immunity from noise and interference even when running next to line power! The HD VB31PT also provides a unique mounting tab and strain relief.
