Closed-circuit television system (CCTV) uses video cameras to transmit a signal to a specific place. CCTV relies on strategically placed cameras and monitoring the camera’s output on monitors. The cameras communicate with monitors and/or video recorders via private coaxial cable runs or wireless communication links.

Modern CCTV displays color, high-resolution displays, as well as the ability to zoom in on an image or track something.

Closed-circuit television system (CCTV) commonly used for a variety of purposes, including:

  • Maintaining perimeter security in medium- to high-secure areas and installations.
  • Observing behavior of incarcerated inmates and potentially dangerous patients in medical facilities.
  • Traffic monitoring.
  • Overseeing locations that would be hazardous to a human, for example, highly radioactive or toxic industrial environments.
  • Building and grounds security.
  • Obtaining a visual record of activities in situations where it is necessary to maintain proper security or access controls (for example, in a diamond cutting or sorting operation; in banks, casinos, or airports).
