Security Services Surveillance and Monitoring 2 — Questions and Answers
Question 1: What is a 'blind spot' in surveillance?
- A malfunction in the camera recording system
- An area not covered by any camera or sensor (Correct answer)
- A camera with a narrow field of view
- A security guard's limited field of personal vision
Correct answer: An area not covered by any camera or sensor
A blind spot is an area within a facility that is not covered by any surveillance camera or sensor, representing a vulnerability in the security system.
Question 2: What is the recommended practice for storing surveillance video recordings?
- Storing footage on a single local drive for easy access
- Storing footage securely for a defined retention period with access controls and backups (Correct answer)
- Deleting footage after 24 hours to save storage space
- Storing footage on a public network for easy retrieval
Correct answer: Storing footage securely for a defined retention period with access controls and backups
Surveillance footage should be stored securely for a defined retention period (often 30 to 90 days), with access controls and backups to ensure its availability for investigations.
Question 3: What does 'NVR' stand for in surveillance systems?
- Network Video Recorder (Correct answer)
- Night Vision Range
- Networked Video Review
- Non-Volatile Recording
Correct answer: Network Video Recorder
An NVR (Network Video Recorder) processes and records video data from IP cameras, transmitting the data over a network.
Question 4: Why is camera placement at entry and exit points important?
- To greet visitors on a screen in the lobby
- To capture clear images of individuals entering and leaving for identification and accountability (Correct answer)
- To monitor vehicle traffic flow only
- To comply with building codes and zoning regulations
Correct answer: To capture clear images of individuals entering and leaving for identification and accountability
Placing cameras at entry and exit points captures images of everyone who enters and leaves, providing critical identification data for security incidents.
Question 5: What is 'night vision' or 'infrared' capability in security cameras?
- The ability to record in full color during the daytime
- The ability to capture clear images in low-light or no-light conditions using infrared light (Correct answer)
- A feature that adjusts camera angles automatically at night
- A power-saving mode that reduces camera usage at night
Correct answer: The ability to capture clear images in low-light or no-light conditions using infrared light
Infrared cameras use invisible infrared light to illuminate and capture footage in darkness, maintaining surveillance capability 24 hours a day.
Question 6: What is the purpose of a 'security control room' or monitoring center?
- A secure storage room for security equipment
- A centralized location where security personnel monitor multiple systems and coordinate responses (Correct answer)
- A room used exclusively for security guard meetings and briefings
- A secure communication hub only
Correct answer: A centralized location where security personnel monitor multiple systems and coordinate responses
A security control room serves as the nerve center of a security operation, where personnel monitor cameras, access control systems, alarms, and coordinate incident response.
