Why each option

CCTV camera systems provide continuous, recorded visual surveillance of physical perimeters and entry points, making them the best solution for 24-hour monitoring.

AUse fences in the entrance doors.

Fences are a physical deterrent and access control barrier, but they do not provide monitoring or detection of who is approaching or attempting entry.

BInstall a CCTV with cameras pointing to the entrance doors and the street.Correct

Closed-circuit television (CCTV) systems allow continuous 24-hour visual monitoring and recording of physical perimeters and entrance doors without requiring constant human presence. Recorded footage provides forensic evidence in the event of an incident, and modern systems support remote viewing and alerts. This directly fulfills the CEO's requirement for around-the-clock physical surveillance of both the entrance and street perimeter.

CUse an IDS in the entrance doors and install some of them near the corners.

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

DUse lights in all the entrance doors and along the company's perimeter.

Perimeter lighting improves visibility and acts as a deterrent, but it does not actively monitor, record, or alert security personnel to physical threats.
