This differs from broadcast television where the signal is transmitted over the air and viewed with a television. For example, a CCTV system can provide the means to assess an alarm generated by an intrusion detection system and record the event.Ī CCTV system links a camera to a video monitor using a direct transmission system. CCTV systems are often used to support comprehensive security systems by incorporating video coverage and security alarms for barriers, intrusion detection, and access control. A CCTV system serves mainly as a security force multiplier, providing surveillance for a larger area, more of the time, than would be feasible with security personnel alone. Such efforts should be undertaken only in consultation with organizations experienced in the various phases of planning, constructing, testing, operating, and maintaining comprehensive CCTV systems for access control, surveillance, or forensic applications.ĬCTV systems provide surveillance capabilities used in the protection of people, assets, and systems.
