Video Baluns | UTP Balun
CCTV video baluns, also known as UTP baluns, allow traditional coax cable to be replaced by category 5 and other forms of twisted pair wire in CCTV video camera & surveillance installations. Video baluns allow installers to use more cost effective structured cabling techniques to wire security cameras. By using video baluns, UTP wire such as cat-5 can be run over longer distances easier than coax cable and for less money. Active balun transceivers enable UTP wires for cameras to be run distances up to 3,000 feet. CCTV Camera Pros belives that we supply the best UTP video baluns on the market.

Using UTP BalunsRG59 Coax cable is more typically used for CCTV cabling, but in some cases it
makes more sense to use Cat5 cable instead of RG59. One such case is when transmitting the surveillance video
signal over long distances. A UTP balun, aka video balun, converts a 75 ohm video signal to 100 ohm impedance for Cat5 cable. On the other end, the receiving balun then converts the signal back to 75 ohms, so in order to use baluns for video transmission, the application needs 2 baluns (one on each end of the Cat5 cable run).
Using baluns can save a lot of time for an installation. For example, if you are in a an office building and need to install a security camera, you can see if there are unused Cat3 or CAT-5 telephone
lines. This can possibly eliminate the need to run coax cable from one floor of the building to another.
Another advantage of transmitting video over Cat5 cable is that you have multiple pair of
wires. Typically you have 4 pairs of 22 gauge wire in a cat-5e cable, so you can use one cable for 4 cameras.
