What is a Closed Circuit TV (CCTV) System?
Closed circuit television (CCTV) is a TV system whose signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. Closed circuit television systems rely on strategic placement of cameras and private observation of the cameras' 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.
Older CCTV systems used small, low-resolution black and white monitors with no interactive capabilities. Today's CCTV displays are high-resolution color, providing the CCTV administrator with the ability to zoom in on an image or track something (or someone). Talk CCTV allows the administrator to speak to people within range of the camera's associated speakers.
CCTV may be used for a variety of purposes:
- Maintaining perimeter security
- Monitoring traffic
- Obtaining a visual record of an individual's activity
Many of today's residential security systems offer CCTV capabilities incorporated in the security system. Click here to learn more.
