What is the primary purpose of integrating CCTV with an alarm system?
Answer: To enable video verification of alarm events
Integrating CCTV with alarm systems allows operators to visually verify whether a triggered alarm represents a genuine security threat before dispatching a response.
What is 'alarm call-up' in a CCTV system?
Answer: The automatic display of a specific camera view when an associated alarm triggers
Alarm call-up automatically switches the monitor display to show the camera associated with a triggered alarm, enabling immediate visual assessment of the event.
Which detector is most commonly integrated with CCTV to trigger motion-based recording?
Answer: Passive Infrared (PIR) detector
Passive Infrared (PIR) detectors sense heat signatures from moving people and are widely used to trigger CCTV recording when motion is detected in a protected zone.
What is a false alarm in the context of an integrated CCTV and alarm system?
Answer: An alarm triggered by a non-threatening event rather than an actual security breach
A false alarm is triggered by non-threatening causes such as animals, environmental conditions, or equipment faults rather than an actual intrusion or security event.
What typically happens to the CCTV recording frame rate during an alarm event in an integrated system?
Answer: Recording frame rate increases to capture higher detail of the incident
Integrated systems commonly increase the recording frame rate when an alarm triggers, providing smoother and more detailed footage that is more useful for evidence and incident review.
What is 'video verification' in an alarm-integrated CCTV system?
Answer: Using live or recorded camera footage to confirm whether an alarm represents a genuine security threat
Video verification involves an operator viewing live or recorded footage to confirm whether a triggered alarm is a genuine incident, helping to reduce unnecessary emergency service dispatches.
Which interface method is most commonly used to connect an alarm panel to a CCTV system?
Answer: Contact closure (dry contact) input
Contact closure (dry contact) is the standard method for triggering CCTV systems from alarm panels, providing a simple open/close circuit signal that is reliable and widely supported across equipment brands.
