CCTV cables are offered in two types namely 4+1 CCTV Cables and 3+1 CCTV Cable. Coaxial cables form the carrier for video signal and the other '4 cores' or '3 cores' from the carriers for power. Coaxial cables are designed to transmit the complete video frequency range with the minimum distortion or attenuation, making them an excellent choice for CCTV. Remistar CCTV Cables are designed to optimize the quality of video signals, which are transmitted through the Coaxial cable in the CCTV cable. The Coaxial cable consist of solid aanealed bare copper conductor of electrolytic grade which is insulated with foamed dielectric , aluminium foil taped, jelly flooded , braided with AI. Alloy and then jacketed with UV PVC.
Top most quality of coaxial cable in CCTV cables ensures distortion free video signals anf thus clear picture over complete low frequency bandwidth of transmission in such applications. The impedance of coaxial cable is 75, which matches the CCTV equipment. This matching ensures adequate signal strength, no reflection and best picture quality. In CCTV the coaxial cable is of type RG-59 which has highest attenuation compared to RG-6 and RG-11. Hence, it is recommended for use only for distances up to 300ft. Foamed dielectric delivers excellent electrical properties such as low capacitance and high velocity of propagation. This results in low-loss characteristics and reduced attenuation of the video signal. Aluminium foil and AI. Alloy branding of 60% coverage ensures complete elimination of MEI/RFI from the video signals and also provides a reduces DC Resistance ground path. Jacketing with UV PVC is ideal for all indoor and outdoor applications.
