What is a CCTV system and how is it used in Singapore security?
Answer: A Closed-Circuit Television system using cameras to monitor and record activities at a premises for security, deterrence, and evidence collection
CCTV systems are fundamental to modern security in Singapore. They provide real-time monitoring, deter crime, record evidence for investigations, and can be integrated with access control and alarm systems.
What should a security officer monitoring CCTV cameras focus on?
Answer: Suspicious behaviour, unauthorised access, safety hazards, unattended bags, crowd buildup, and any anomalies from normal patterns
Effective CCTV monitoring requires active scanning for anomalies: suspicious persons, unusual behaviour, unattended items, safety hazards, blocked exits, and any deviation from normal activity patterns.
What is an 'intrusion detection system' in Singapore security?
Answer: Electronic systems (sensors, alarms, motion detectors) that detect and alert security to unauthorised entry or movement in protected areas
Intrusion detection systems use various sensors (infrared, microwave, vibration, magnetic contacts) to detect unauthorised entry. When triggered, they alert the security team through alarms and notifications.
What is the proper procedure for responding to an alarm activation?
Answer: Assess the alarm type and zone, dispatch a security officer to investigate, verify whether it is a genuine threat or false alarm, and reset the system after confirmation
Every alarm must be treated as genuine until proven otherwise. Identify the alarm zone, dispatch investigation, approach cautiously, verify the cause, take appropriate action, document, and reset the system.
What is a 'guard tour system' used for in Singapore security operations?
Answer: An electronic system that verifies security officers complete their patrols at designated checkpoints and times, ensuring accountability
Guard tour systems use checkpoints (NFC tags, QR codes, or RFID) at patrol locations. Officers scan each point, creating a digital record of patrol times and routes for supervisor verification.
How should CCTV footage be handled and stored in Singapore?
Answer: Store securely with restricted access, maintain recordings for the required retention period, protect from tampering, and provide to police when lawfully requested
CCTV footage must be stored securely with access limited to authorised personnel. Retention periods follow PDPA guidelines (typically 30-90 days). Footage must not be tampered with and must be available for lawful investigation.
