CCTV Security System Installation
CCTV (closed-circuit television) is a TV system in which signals are not publicly spread but are observed, mainly for surveillance and security purposes.
CCTV depends on planned placement of cameras, and observation of the camera’s input on monitors somewhere. Because the cameras interconnect with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the title “closed-circuit” to indicate that access to their content is limited by design only to those able to see it.
