Question 1: What is the primary purpose of CCTV in security?
- To provide employee entertainment
- To deter crime, monitor activity, and provide evidence for investigations (Correct answer)
- To track employee productivity only
- To replace security guards entirely
Correct answer: To deter crime, monitor activity, and provide evidence for investigations
CCTV systems deter criminal activity through visible surveillance, allow real-time monitoring, and provide recorded evidence for investigations.
Question 2: What is 'pan-tilt-zoom' (PTZ) in reference to security cameras?
- A type of camera recording format
- A camera that can rotate horizontally, tilt vertically, and zoom in or out (Correct answer)
- A camera installation method
- A wireless camera connection type
Correct answer: A camera that can rotate horizontally, tilt vertically, and zoom in or out
PTZ cameras can be remotely controlled to pan (rotate side to side), tilt (move up and down), and zoom, providing flexible coverage of large areas.
Question 3: What is 'video analytics' in surveillance systems?
- Software that automatically analyzes video footage to detect specific events or behaviors (Correct answer)
- The process of manually reviewing recorded footage
- A video editing tool for security footage
- A camera resolution specification standard
Correct answer: Software that automatically analyzes video footage to detect specific events or behaviors
Video analytics uses algorithms to automatically analyze video feeds, detecting events like motion, loitering, or perimeter breaches in real time.
Question 4: What is a 'DVR' in a surveillance system?
- Digital Video Recorder — a device that records video from security cameras (Correct answer)
- Direct Video Relay — a camera transmission system
- Digital Visual Resolution — a camera specification
- Dynamic Video Retrieval — a search system for footage
Correct answer: Digital Video Recorder — a device that records video from security cameras
A DVR (Digital Video Recorder) records and stores video footage from security cameras, allowing playback and review of past events.
Question 5: What is 'camera coverage' in surveillance planning?
- The warranty period for security cameras
- The area visible to cameras, ensuring all critical areas are monitored without blind spots (Correct answer)
- The total number of cameras in a system
- The height at which cameras are mounted
Correct answer: The area visible to cameras, ensuring all critical areas are monitored without blind spots
Camera coverage refers to ensuring that all critical areas of a facility are visible to at least one camera, eliminating blind spots.
Question 6: What is 'motion detection' in surveillance cameras?
- A feature that turns off cameras when no one is present
- A feature that triggers recording or alerts when movement is detected in the camera's field of view (Correct answer)
- The camera's ability to physically track a moving subject
- A sensor that detects when a camera is being tampered with
Correct answer: A feature that triggers recording or alerts when movement is detected in the camera's field of view
Motion detection automatically triggers recording or sends alerts when movement is detected in a camera's field of view, reducing storage needs and enabling faster response.
