Cat 5 cable has become increasingly popular for CCTV installations. It is easy to install and produces excellent results with clear video signals over considerable distances.
Our newly developed Cat5-CCTV cable has been jointly developed by ourselves and a major cable manufacturer to provide superb results in video signal transmission. Featuring quality copper cores, it can often outperform standard computer Cat5 producing a better picture quality over longer distances.
To make the cable suitable for most installations, it is available with either a black or white outer sheath so it looks right on either white or dark skirting boards or building fascias.
The cores are colour coded in a meaningful and engineer-friendly colour code as below:
Pair 1 - Orange & White (White with a orange stripe) Pair 2 - Brown & White (White with a brown stripe) Pair 3 - Blue & White (White with a blue stripe) Pair 4 - Green & White (White with a green stripe)
Whereas co-ax cables are classed as an "unbalanced" mode of video transmission, Cat5 twisted pair is know as a balanced mode. In this balanced mode, the two cores carrying the video signal are balanced to a particular reference point and the cable twists enable a uniformed rejection of interference, effectively cancelling it out. To produce a balanced signal, equipment known as BALUNs are used, standing for BALanced to UN balanced.
The Cat5 cable can be used for short distances without baluns but they do obviously improve the cable's performance resulting in a better picture quality. |
