The VB31AT is a unique video balun which provides an economical means of sending video and camera power over a standard category cable. Video is sent over one pair and camera power is sent over two of the remaining pairs. A mini-coax pigtail with male BNC is used on the VB31AT. A pair of wires are provided for power connection. Connections to the Category cable are made via an RJ45 connector.

The VB31AT video and power balun provides the same high immunity to noise and interference as all of the Nitek baluns. This simplified wiring scheme provides a convenient method of powering the camera and allowing for quicker and easier installations. The RJ45 modular jack uses standard 568B wiring so spare network cables can be used.
