HENRICH CCTV  Cables are offered in RG**9 seamese cable , 4*1 CCTV and 3*1 CCTV Cables. Coaxial cables form the carrier for video signal and the other 4 cores or 3 cored form the carriers for power. Coaxial cables are designed to transmit the complete video frequency range with minimum distortion or attenuation, making them an excellent choice for CCTV. HENRICH 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 Nylon foamed dielectric, aluminium foil taped, jelly flooded, braided with Al. Alloy and then jacketed . Topmost quality of construction of coaxial cable in HENRICH CCTV cables ensure distortion free video signals and thus a clear picture over complete low frequency bandwidth of transmission in such applications. The impedance of coaxial cable is *5, which matches the CCTV equipment. This matching ensure adequate signal strength, no reflection and best picture quality. In CCTV the coaxial cable is of type RG**9, which has highest attenuation compared to RG*6 to RG**1. Hence it is recommended for use only for distance up to **0ft to ***0ft. Foamed Nylon 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 *0% coverage ensure complete elimination of EMI/RFI from the video signals and also provided a reduced DC resistance ground path.
