Can the closed-circuit line be a monitoring line?
Closed-circuit cable television also called cable TV signal line line, closed-circuit television signal is divided into core and shielding layer of two parts, the middle of that hard root as a signal, while the outer layer of the mesh wire core and aluminum foil as the signal shielding layer, played the role of anti-interference.
Yes, but the quality of the closed lines, especially the intensity is less, so the life expectancy is shorter and the transmitted signal attenuation is greater.
Surveillance video cable is a kind of wire and cable used to connect security surveillance cameras and real terminals (computers or monitors, etc.) to transmit image data captured by surveillance cameras. Surveillance video cable is a kind of coaxial cable, also called coaxial video line, the letter code is SYV, so it is also called SYV cable or video coaxial cable.
