Question

Options

• AKey card
• BBiometric devices
• CIntrusion detection systems
• DCCTV Cameras

• A
  16% (7)
• B
  2% (1)
• C
  9% (4)
• D
  73% (32)

Explanation

CCTV Cameras (D) are the correct answer because they continuously record video footage, providing both real-time detection and a permanent historical record that investigators can review after the incident - exactly what's needed for post-robbery verification and analysis.

Why the others are wrong:

• Key card (A): An access control tool for authorized entry; it doesn't capture or store visual evidence of events.
• Biometric devices (B): Used to verify identity at the point of access, but they don't record footage or provide a historical playback of what occurred.
• Intrusion detection systems (C): Alert personnel when a breach occurs (detection), but they don't capture visual evidence suitable for post-incident forensic analysis.

Memory tip: Think of CCTV as the "crime scene historian" - it's the only option here that both sees and remembers what happened, making it invaluable after the fact. The other three options are all gate-keeping tools (they control or alert), not recording tools.
