CCTV

CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.

CCTV relies on strategic placement of cameras and private observation of the camera’s input on monitors. The system is called “closed-circuit” because the cameras, monitors and/or video recorders communicate across a proprietary coaxial cable run or wireless communication link.  Access to data transmissions is limited by design.
