Which CCTV camera type is BEST suited for monitoring a large open parking lot that requires wide-area coverage?
Answer: Pan-Tilt-Zoom (PTZ) camera
PTZ cameras can be remotely directed and zoomed to cover large areas and track moving subjects, making them ideal for expansive open spaces like parking lots.
In a video surveillance system, what is the primary function of a Video Management System (VMS)?
Answer: To centrally record, manage, and retrieve video from multiple cameras
A VMS provides centralized recording, live monitoring, search, and playback of video from multiple cameras across a facility or enterprise.
What is the minimum video retention period most commonly recommended by security standards for high-security facilities?
Answer: 30 days
30 days of video retention is a widely recommended baseline for high-security environments, ensuring footage is available for post-incident investigations.
An intrusion detection system (IDS) generates a 'false positive.' This means:
Answer: An alarm was triggered when no actual intrusion occurred
A false positive occurs when the system triggers an alarm in the absence of an actual threat, wasting response resources and potentially causing alarm fatigue.
Which type of motion detector uses microwave energy to detect movement within a protected area?
Answer: Microwave sensor
Microwave sensors emit microwave pulses and detect movement by measuring changes in the reflected signal, and can penetrate non-metallic objects unlike PIR sensors.
A dual-technology motion detector combines PIR and microwave sensing primarily to:
Answer: Reduce false alarms by requiring both technologies to trigger simultaneously
Requiring both PIR and microwave sensors to trigger simultaneously reduces false alarms, since environmental factors that fool one sensor rarely fool both at the same time.
