CCTV (closed-circuit television) is a TV framework in which signals are not freely conveyed but rather are observed, essentially for observation and security purposes.
CCTV depends on key position of cameras and private perception of the camera’s contribution on screens. 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.
Older CCTV systems used small, low-resolution black and white monitors with no interactive capabilities. Modern CCTV displays can be high-resolution color, providing the CCTV manager with the administrator to zoom in on a picture or track something (or somebody). Talk CCTV enables the executive to address individuals inside scope of the camera’s related speakers
