What is a key component of physical security measures?

A key component of physical security measures is the use of CCTV surveillance systems. These systems play a critical role in monitoring and recording activities within a secured area. By deterring potential threats and providing a means to gather evidence in case of incidents, CCTV surveillance enhances the overall security of a facility.

The presence of cameras can discourage unauthorized access and help in real-time monitoring, which is vital for responding swiftly to any suspicious activities. Additionally, recorded footage can be invaluable for investigations, enabling security personnel to track events and identify individuals involved in security breaches.

While other options like access control systems, alarm systems, and lighting systems contribute significantly to physical security, they serve different functions. Access control systems regulate who can enter specific areas, alarm systems notify personnel of breaches or unauthorized access, and lighting systems improve visibility in and around secured locations. However, CCTV surveillance directly aids in monitoring, deterrent, and incident documentation, making it a foundational element of a robust physical security strategy.
