An enterprise recently moved to a new office and the new neighborhood is a little risky. The CEO wants to monitor the physical perimeter and the entrance doors 24 hours. What is the best option to do

Fences are physical deterrents and barriers, not monitoring tools - they prevent unauthorized entry but provide no visibility or recording of activity.

Closed-circuit television (CCTV) systems provide continuous, recorded visual monitoring of physical perimeters and entrance points around the clock. Cameras can be positioned to cover both the entrance doors and the street, giving security personnel real-time visibility and recorded evidence. This directly addresses the CEO's requirement for 24-hour perimeter and door monitoring.

An IDS (Intrusion Detection System) is a network security tool that monitors digital traffic for threats, not a physical perimeter monitoring solution.

Lighting improves visibility for human guards but does not provide automated 24-hour monitoring, recording, or alerting on its own.
