CCTV CABLES

POLYCAB CCTV Cables are offered in two types namely 4 + 1 CCTV Cable and 3 + 1 CCTV Cable. Coaxial cable: form the carrier for video signal and the other ‘4 cores’ or ‘3 cores’ form the carriors for power. Coaxial cables are designed to transmit the complete video frequency range with minimum distortion or attenuation, making them are excellent choice for CCTV.

POLYCAB 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 consists of solid annealed bare copper conductor of electrolytic grade which is insulated with foamed dielectric, aluminium foil taped, jolly flooded, braided with Al. Alloy and then jacketed with UV PVC. Topmost quality of construction of coaxial cable in Polycab CCTV cables ensures distortion free video signals and thus a clear picture over complete low frequency bandwidth o 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 o 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 3001t.

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 Al. Alloy braiding of 60% coverage ensures complete elimination of MERFI from the vided signals and also provides a reduced DC resistance ground path. Jacketing with UV PVC is ideal for all indoor and outdoor applications.
