Multi-Channel
Active Baluns
Security camera networks require lots of cables. When laying
long runs of cables the installers usually have a choice
between using CAT5 cable or coaxial cable. CAT5 cable is
cheaper than coax cable, but has different electrical and
physical characteristics.
You can't just connect the wires - you'll lose signal
strength and picture quality. A video balun corrects this
problem by balancing impedance and other electrical
characteristics, which minimizes signal loss and noise.
It's important to use
video baluns when sending video over Cat5 since the
impedance specifications of Cat5, Cat5e and Cat6 are 100
ohms. Video requires 75 ohm impedance and you'll introduce
artifacts to your video without a balun. Basically, if
there's an impedance mismatch the signal will be reflected
from the receiver back to the transmitter causing delays in
the signal transmission; the delays have a ghosting effect
on the picture.

 Your CCTV video over cat5 installation has never been easier
and more cost effective. Balun is the key component that
allows you to transmit VGA, RGB, YPbPr. YCbCr, S-Video and
Composite video or audio over
Cat5.
