Why each option
CCTV with cameras covering the entrance doors and street perimeter provides continuous 24-hour visual monitoring, directly fulfilling the CEO's requirement to observe physical access points around the clock.
Fences are a physical barrier control that restricts entry but do not provide monitoring or surveillance of who approaches or attempts access.
A CCTV system with strategically placed cameras provides real-time and recorded visual coverage of both the building perimeter and entrance points continuously without requiring human presence. This is the standard physical security control used for 24/7 surveillance and aligns with the specific requirement to monitor the perimeter and entry doors. It also enables post-incident review and can serve as a deterrent against unauthorized physical access.
An IDS (Intrusion Detection System) is a network security tool that detects anomalous network traffic, not a physical perimeter monitoring solution.
Lighting improves visibility and acts as a deterrent but does not actively monitor, record, or alert on activity at entrances or along the perimeter.
