Which two security technologies are commonly used in violence prevention?

• A. CCTV surveillance and panic button systems
• B. CCTV surveillance and visitor screening
• C. Access control systems (badges/PINs) and CCTV surveillance
• D. Personal alarms and visitor screening

Answer: (B)

This question is about building a layered, preventive approach to violence by combining monitoring with pre-entry vetting. CCTV surveillance provides ongoing visual coverage of the premises, which helps staff notice unusual behavior early, deter potential incidents, and gather evidence for investigations or post-incident review. Visitor screening adds a proactive filter before anyone enters: verifying identities, confirming appointments or expected visitors, and screening for risk signals or prohibited items. When used together, these two technologies cover both what’s happening inside the space and who is allowed to enter, reducing the chance of a threat getting through and speeding up a safe response if something occurs. While other tools like panic buttons or strict access control have value, they don’t offer the same combination of broad situational awareness and pre-entry risk reduction that CCTV with visitor screening provide.
