Which physical security control uses cameras and recording devices to monitor activity in an area?

• A. Perimeter fencing
• B. Video surveillance
• C. Intrusion detection system
• D. Access control system

Answer: (B)

Video surveillance is the physical security control that uses cameras and recording devices to observe and document activity in a space. Cameras provide real-time monitoring, and recording devices store footage for later review, supporting quick response to incidents and as evidence in investigations. It serves as both a detection and deterrence measure, since people know they may be observed and recorded. Perimeter fencing is a barrier designed to block access but doesn’t involve ongoing observation. An intrusion detection system relies on sensors to detect unauthorized entry and trigger alerts, not continuous video monitoring. An access control system manages who can enter an area, but it doesn’t provide ongoing visual observation of the space.
