The Nitek Video Balun Combiner for Twisted Pair VB 31AT is a unique transmission device 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
the two of the remaining pairs. A mini-coax pigtail
with male BNC is used on the VB-31AT. A pair of
wires are provided for power connection.
Connections to the Category cable are made via an
RJ45 connector. The VB31AT video 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, allowing for quicker
and easier installations. The RJ45 modular jack uses
standard 568B wiring so spare network cable can be
used.
