A security system with a camera that captures an image, converts it to a video signal, and transmits it to a monitoring station defines __________.

• A. Video Surveillance System
• B. Access Control System
• C. Alarm System
• D. Closed Circuit Television (CCTV)

Answer: (D)

The key idea is a system where a camera feeds video signals over a private, dedicated path to a specific monitoring point. This is what Closed Circuit Television, or CCTV, describes: cameras capture images, convert them into a video signal, and transmit that signal to a monitoring station for viewing. It emphasizes the closed, private loop between cameras and monitors, rather than broad networked access or integration with other security functions.

A video surveillance system is related but broader; it may involve recording, playback, and possibly remote viewing over networks, not necessarily a strict closed loop to a single monitoring station. An access control system handles door openings and permissions, and an alarm system deals with triggering alerts from sensors. So the scenario fits CCTV best because it centers on the camera-to-monitoring-station video feed within a closed circuit.
