Can we use video balun with coaxial cable?
By using a video balun it’s possible to replace the traditional coaxial cable such as RG59 or RG11 and use cat5 cables to transmit the video over long distances. A pair of wires are used to connect the UTP cable to the balun and a BNC connector is used on the coaxial cable to connect to the other end of the balun.
How many video balun is need in UTP cable for CCTV transmission?
Using UTP Baluns 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. In order to use baluns for video transmission, the application needs 2 baluns (one on each end of the Cat5 cable run).
What is a CAT5 balun?
Video baluns, also known as CAT5 baluns, enable security installers to use CAT5 cable to run video (and optionally power) for CCTV cameras. A video balun is placed on both ends of the CAT5 cable run and uses one of the the twisted pairs from the CAT5 cable to transmit the video from the camera to a DVR or monitor.
What is the purpose of a video balun?
A Video Balun enables the transmission of video using unshielded twisted pair wire instead of coaxial cable. The word “balun” comes from combining the terms balanced and unbalanced. The function of a balun is to transform an unbalanced signal into a balanced signal.

How does a video balun work on a cat5 cable?
A video balun is placed on both ends of the CAT5 cable run and uses one of the the twisted pairs from the CAT5 cable to transmit the video from the camera to a DVR or monitor. There are also multi-camera baluns that can use the four twisted pairs in CAT5 to transmit the video for up to four cameras.
