Security Labs professional grade camera extension cables with locking BNC video connectors are used as the standard on all professional CCTV equipment. The 75 Ohm video conductor is surrounded by a heavy copper braided shield that provides maximum protection from stray R.F. (radio frequency), digital processing and radiated power signals. Gold plated center conductor pins minimize low signal loss and help provide high resolution display results. The twin molded rubberized jacket cable also supplies power to the camera via 20 AWG conductors that are terminated with a 2.1 mm DC power jack and plug. A BNC barrel connector (double female) is included for added versatility.
