Which feature helps secure the facility during off-hours?

• A. Monitored CCTV
• B. Alarm systems
• C. Access control systems (cards/codes)
• D. Well-lit exteriors

Answer: (C)

Controlling who can enter the building after hours is the most effective way to prevent unauthorized access. An access control system uses credentials such as cards or numeric codes to grant or deny entry at doors. It enforces time-based restrictions, so doors stay locked for everyone except authorized personnel, and it creates a traceable record of who entered and when. If a badge is lost or someone leaves, access can be revoked quickly, and additional layers like two-factor authentication can be added for stronger security. This approach directly manages entry points, which is crucial when the facility is closed and the risk of unauthorized access is highest.

Monitored CCTV helps you see and review what happens, acting as a deterrent and providing post-event evidence, but it doesn’t stop entry on its own. Alarm systems alert you to breaches, yet they depend on a response after the fact rather than preventing the breach. Well-lit exteriors improve visibility and deter some attempts, but lighting alone doesn’t control access or identify individuals. Access control with cards or codes uniquely provides gatekeeping at the doors during off-hours.
