Closed Circuit Television (CCTV) is a system where the circuit in which the video is transmitted is closed and all the elements (camera, display monitors, recording devices) are directly connected.
This is unlike broadcast television where any receiver that is correctly tuned can pick up and display or store the signal. In the past, these signals would be transmitted to a monitor equipped with a videocassette recorder, but these have been all but totally replaced by digital video recorder (DVR) systems that can store far more video and back up data automatically.
It has become an increasingly important factor in security and surveillance for governments, law enforcement, schools, businesses, and even homeowners. Let’s take a closer look at the many ways in which CCTV is used today.
- 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)
