Video Balun Transceiver for UTP Category Cables

The Nitek Video Balun Transceiver for Twisted Pair VB31PT 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 up to 750 feet with other passive balun transceivers and up to 1,500 feet with TR515 single channel and model 51 series hubs.

The VB31PT is compatible with all of the “up-thecoax” 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 VB31PT is designed to provide superior immunity from noise and interference even when running next to line power! The VB31PT also provides a unique mounting tab and strain relief.
 

VB31PT features include:

  • Quality video over ordinary twisted pair cable
  • Immunity to noise and interference
  • Passive devices - do not require power
  • Video & P/T/Z over a single pair (with up-the-coax systems)
  • Mini-coax pigtail for in-camera or dome mounting
  • Weatherproof design
  • Easier to install than coax
  • Compatible with all twisted pair equipped cameras, enclosures and domes
