Continuous surveillance is very important in all public areas like banks, offices, airports, bus/railway stations and shopping complexes. In sensitive areas surveillance and monitoring is very crucial and 3rd eye observation also required. Sensitive cameras are connected to the data centre with high precision cable circuits for monitoring and recording every activity/movement.
SUDHAKAR 3+1 CCTV Cables and 4+1 CCTV Cables are designed to high definition technology of video signals, which are transmitted through the Coaxial cable in the CCTV.
75 ohm Coaxial cable consists of electrolytic grade solid annealed bare copper conductor which is insulated with Advanced FEP (Fluorinated Ethylene Propylene) Foam technology for improving the dielectric and lower attenuation. The First shield conductor is made of a specially designed poly-aluminium tape, bonded to the FEP foam. The tape has sufficient overlap longitudinally over the foam dielectric, jelly flooded. The Aluminium alloy wire braiding with more than 65% coverage, high temperature withstands sheathed with UV resistant property.
The other cables of electric wires consist of solid annealed bare copper conductor, insulated with Polythene, colour coded as per specifications. These insulated cores are laid up along with co-axial cables and outer sheath specially formulated PVC in black colour with UV resistance.
