There are many different cables used in CCTV systems but the choice of cable comes down to a small(ish) number of criteria. Budget is often a massive concern, but the numbers of cameras involved, the length of cable run required, the power requirements, and the need to integrate with other systems should all be given significant consideration as appropriate.
Traditionally coaxial cable has been commonly used for CCTV purposes, and its use has been so prevalent that most CCTV cameras are produced with a coaxial BNC connector. However not choosing the right coaxial cable can cause an issue with the quality of camera view.
Most coaxial cable for CCTV use today is either an RG59 or 'combo' coaxial cable that also includes an accompanying power core. With Full HD now available via Coaxial cable (e.g. SDI, AHD, TVI etc) the highest possible quality of coax should be used to lessen interference and ensure the best possible picture quality, as poor quality coaxial cable is prone to signal loss, especially the high-frequency elements, leading potentially to a noticeable loss of picture quality and signal distances, especially in Full HD 1080P images. One of the most important aspect to consider in coaxial cable is it suitable for today's technology and will it go the distance.?
Ness Quality Coaxial Cable is designed to be used with all CCTV systems from low-resolution SD images up to full HD (1080P) SDI. Beware of cheaper inferior coaxial cables that may cause your CCTV systems to have an issue.
