Which security measure is described as a tool to monitor facility activity and deter unauthorized access?

• A. Visitors allowed during hours
• B. Doors secured at all times
• C. Security cameras
• D. Staff training

Answer: (C)

Monitoring facility activity and deterring unauthorized access is most effectively achieved through security cameras. They provide continuous visual surveillance of entry points and restricted areas, enabling real-time observation and later review of events. The presence of cameras also acts as a deterrent, making potential intruders think twice because their actions can be recorded and identified. This capability supports immediate monitoring, incident investigation, and overall security documentation. While keeping doors secured at all times and providing staff training are important components of security, they don’t offer the same ongoing, observable monitoring and deterrent effect that cameras deliver.
