What are three common perimeter security measures for a manufacturing facility?

• A. Security cameras only, no lighting, no barriers.
• B. Fences, access-controlled gates, and CCTV surveillance with lighting.
• C. RFID cards, biometric only, drones.
• D. Security guards only.

Answer: (B)

Perimeter security for a manufacturing facility relies on layering barriers, controlled entry, and monitoring to deter and detect intruders at the boundary. The combination of fences, access-controlled gates, and CCTV surveillance with lighting provides multiple, complementary defenses: a physical barrier that slows and channels entry, gates that restrict who can get through and when, and cameras with lighting that deter activity and provide visible and recorded evidence of any attempt to breach the perimeter. Lighting also enhances camera clarity at night, making detection and later investigations easier. This layered approach creates more points of detection and deterrence than any single measure could achieve.

Choosing only cameras with no lighting or barriers leaves the site vulnerable to quick, undetected access. Focusing on credentials like RFID or biometrics alone misses the need for a physical boundary and robust lighting, and adds complexity without addressing entry points and nighttime visibility. Relying on security guards alone depends on human presence and vigilance, which can be costly and may still leave gaps during shift changes or low-activity periods.
