What does CCTV stand for in security technology?
Answer: Closed-Circuit Television
CCTV stands for Closed-Circuit Television, a system where video signals are transmitted to a limited set of monitors for security surveillance.
What is the primary purpose of a passive infrared (PIR) motion detector in a security system?
Answer: To detect changes in infrared radiation emitted by warm bodies
A passive infrared (PIR) sensor detects changes in infrared radiation (heat) emitted by people or animals moving through its field of view.
Which type of access control system uses physical characteristics such as fingerprints or retinal scans to verify identity?
Answer: Biometric access control
Biometric access control uses unique physical characteristics — such as fingerprints, retinal patterns, or facial features — to authenticate individuals.
What does PTZ stand for in the context of security cameras?
Answer: Pan, Tilt, and Zoom
PTZ stands for Pan, Tilt, and Zoom, describing cameras that can be remotely directed horizontally, vertically, and can magnify images.
A security officer is monitoring a DVR system. What is the primary advantage of a Digital Video Recorder (DVR) over older analog tape systems?
Answer: DVRs allow continuous recording, easier retrieval, and longer storage capacity
DVRs allow continuous looped recording, rapid search and retrieval of footage, and far greater storage capacity compared to VHS-based analog systems.
What is the purpose of an interlock or 'mantrap' in a high-security facility?
Answer: To allow only one person to pass through a controlled area at a time, preventing tailgating
A mantrap (interlock) is a small enclosed space with two sets of interlocking doors, ensuring only one person can enter the secure area at a time to prevent tailgating or piggybacking.
Which of the following best describes 'tailgating' as a security threat related to access control?
Answer: An unauthorized person following an authorized person through a secured door without using credentials
Tailgating (also called piggybacking) occurs when an unauthorized individual follows closely behind an authorized person to gain access through a controlled entry point without presenting credentials.
