What is the primary benefit of adding a surveillance system to a key-based access control system?

• A. To monitor employee productivity
• B. To deter unauthorized access
• C. To log data access times
• D. To provide internet connectivity

Answer: (B)

The primary benefit of adding a surveillance system to a key-based access control system is to deter unauthorized access. Surveillance systems serve as a visual deterrent by capturing video footage of individuals entering and exiting secured areas. The mere presence of cameras can discourage potential intruders from attempting unauthorized access, as they are aware that their actions are being recorded.

Additionally, should an unauthorized access attempt occur, the recordings can provide valuable evidence for investigations. In contrast, other options such as monitoring employee productivity, logging data access times, or providing internet connectivity do not directly align with the main purpose of enhancing security and preventing unauthorized entry. Thus, incorporating a surveillance system complements the physical security measures of a key-based access system by adding an important layer of deterrence and monitoring.
