RG59 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, typically called "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.

This product device is suitable for being used for interconnect an Intellisystem Technologies wired camera to a Video Server o Video Encoder.

The passive converter ITRJ45 is the most practical to use with twisted pair cable as it does not require an external power supply. At one end it has a BNC connector to connect to the CCTV device (for i. e. camera and monitor). On the other side it has 2 screw terminals to connect one of the four pairs of the CAT5 cable. Two converters are needed for each camera at each end of the twisted pair cable. The device is in fact reversible and functions as a transmitter when located near the camera and as a receiver when positioned near the monitor.
