Question

James was recruited as security personnel in an organization and was instructed to secure the organization's infrastructure from physical threats. To achieve this, James installed CCTV systems near gates, reception, hallways, and workplaces to capture illicit activities inside the premises, identify activities that need attention, collect images as evidence, and aid in an alarm system. Identify the type of physical security control implemented by James in the above scenario.

Options

  • AVideo surveillance
  • BFire-fighting systems
  • CLighting system
  • DPhysical barriers

Explanation

Video surveillance (A) is correct because James deployed CCTV cameras specifically to monitor, record, and deter unauthorized activity - the defining function of a video surveillance system. The scenario explicitly mentions capturing illicit activities, collecting image evidence, and integrating with an alarm system, all hallmarks of CCTV-based surveillance.

Why the distractors are wrong:

  • B (Fire-fighting systems) address fire hazards, not monitoring or access control - a completely different threat category.
  • C (Lighting systems) deter threats through illumination but cannot capture images, identify activities, or serve as evidence.
  • D (Physical barriers) (fences, walls, locks) prevent physical entry but provide no recording, monitoring, or evidentiary capability.

Memory tip: If a security control records and watches, think surveillance. The keyword cluster - CCTV + evidence + alarm integration - always points to video surveillance on exams.

The correct answer is A, video surveillance. CCTV cameras placed at gates, hallways, reception areas, and workplaces are the textbook definition of a video surveillance control, full stop. The scenario spells out exactly what surveillance systems do: capture illicit activity, flag situations needing attention, collect image-based evidence, and integrate with alarm systems. The other options do not fit because fire-fighting systems address fire hazards, lighting systems deter threats through illumination rather than recording, and physical barriers restrict access through structure rather than monitoring behavior.

The question makes this easy because four functions are listed, all pointing to one technology, but D is the trap if you are speed-reading and just see "gates" and assume physical barriers. CCTV hitting all four named purposes (capture, identify, evidence, alarm support) is textbook Video surveillance, so A is the pick and it deserves a card on your D1 interval.

Solid breakdown, though I would add that the "alarm support" function is the one most test-takers underweight, so if your interval deck has room, make that a separate card rather than bundling all four into one.

Physical barriers are the answer because CCTV mounted at gates, reception points, and hallways are literally defining and enforcing physical access zones, which is the textbook function of a barrier control. The cameras do not just observe, they demarcate controlled perimeters and funnel movement the same way a fence or turnstile would, making D the correct classification here.

Zinedine, cameras do not stop anyone from walking through a space, they record what happens so you can detect and review incidents after the fact, which is exactly what makes them detective controls. A fence or a locked turnstile prevents entry, but a CCTV lens just watches.
