CPO Security Technology and Equipment 2 — Questions and Answers
Question 1: What does RFID stand for, and what is its primary use in security access control?
- Remote Frequency Identification Device — used to track patrol officer locations
- Radio-Frequency Identification — used to authenticate proximity cards and key fobs (Correct answer)
- Recorded File and Image Data — used to store surveillance footage
- Rapid Facility Intrusion Detection — used to trigger alarms at entry points
Correct answer: Radio-Frequency Identification — used to authenticate proximity cards and key fobs
RFID (Radio-Frequency Identification) uses electromagnetic fields to automatically identify and authenticate tags embedded in access cards or key fobs when held near a reader.
Question 2: A security officer notices the alarm panel displays a 'tamper' alert. What does this typically indicate?
- A door contact sensor has detected unauthorized entry
- A device casing or wiring has been opened or disturbed, suggesting an attempt to defeat the system (Correct answer)
- The alarm panel battery is low and needs replacement
- A motion sensor has been triggered by an animal
Correct answer: A device casing or wiring has been opened or disturbed, suggesting an attempt to defeat the system
A tamper alert indicates that a security device's housing, wiring, or mounting has been disturbed, which may signal an attempt to defeat or disable the equipment.
Question 3: What is the primary function of a perimeter intrusion detection system (PIDS)?
- To control who enters through gate access points using badge readers
- To detect and alert on unauthorized attempts to breach the outer boundary of a secured area (Correct answer)
- To monitor internal hallways using motion sensors and cameras
- To log and record all authorized entries and exits from a facility
Correct answer: To detect and alert on unauthorized attempts to breach the outer boundary of a secured area
A PIDS is designed specifically to detect unauthorized attempts to cross, climb, or breach the outer perimeter of a secured area, providing early warning before an intruder reaches the facility.
Question 4: What is the purpose of a security alarm's 'entry delay' feature?
- To delay police notification by a set period to reduce false alarm fees
- To give authorized users time to disarm the system after entering through a designated door before the alarm sounds (Correct answer)
- To prevent the system from triggering during routine cleaning shifts
- To delay system startup during power restoration after an outage
Correct answer: To give authorized users time to disarm the system after entering through a designated door before the alarm sounds
The entry delay gives an authorized user a brief window — typically 30 to 60 seconds — to reach the control panel and disarm the system after entering through a designated access point.
Question 5: Which type of security lighting is designed to activate only when motion is detected in an area?
- Standby lighting
- Continuous lighting
- Emergency lighting
- Reactive or motion-activated lighting (Correct answer)
Correct answer: Reactive or motion-activated lighting
Reactive (motion-activated) lighting switches on only when a sensor detects movement, conserving energy while drawing attention to activity in previously dark areas.
Question 6: What is 'video analytics' in the context of modern security camera systems?
- A manual process where officers review camera footage frame by frame
- Software that automatically analyzes video feeds to detect events such as loitering, line crossing, or object removal (Correct answer)
- A method of compressing video files to save storage space on DVR systems
- A system that transmits live video to remote law enforcement monitoring centers
Correct answer: Software that automatically analyzes video feeds to detect events such as loitering, line crossing, or object removal
Video analytics is software-based technology that processes live or recorded video to automatically detect specific behaviors or events, reducing the burden on human operators.
Question 7: A security officer is setting up a two-way radio system. What does the term 'dead spot' refer to?
- A radio channel reserved exclusively for emergency transmissions
- A geographic area where radio signal reception is weak or nonexistent (Correct answer)
- A battery-saving mode that disables the radio when not in use
- A radio frequency blocked by law enforcement for civilian use
Correct answer: A geographic area where radio signal reception is weak or nonexistent
A dead spot is an area where radio signals cannot be reliably received or transmitted, often caused by physical obstructions like thick walls, hills, or electromagnetic interference.
