1. Which of the following is the primary purpose of a CCTV system in a
commercial facility?
A. To control lighting levels
B. To provide real-time video surveillance and recording
C. To monitor temperature fluctuations
D. To regulate access card permissions
Answer: B
Rationale: The main function of a CCTV system is to provide continuous
video surveillance and recording to enhance security and monitor activities
in real-time.
2. What is the typical frame rate for standard CCTV cameras used in
commercial security applications?
A. 1–5 frames per second
B. 10–15 frames per second
C. 24–30 frames per second
D. 60–120 frames per second
,Answer: C
Rationale: Most standard CCTV cameras operate at 24–30 frames per
second, providing smooth video suitable for identifying people and
activities.
3. Which component of a CCTV system converts optical images into
electronic signals?
A. Digital Video Recorder (DVR)
B. Camera lens
C. Image sensor
D. Monitor
Answer: C
Rationale: The image sensor, such as a CCD or CMOS sensor, converts
incoming light from the lens into electronic signals that can be processed
and recorded.
4. In CCTV terminology, what does PTZ stand for?
A. Power, Transmission, Zoom
B. Pan, Tilt, Zoom
C. Peripheral, Technology, Zone
D. Protocol, Timing, Zoom
Answer: B
Rationale: PTZ cameras can Pan (move horizontally), Tilt (move vertically),
and Zoom, allowing flexible monitoring of wide areas.
5. Which video transmission method is most resistant to electromagnetic
interference in CCTV installations?
A. Coaxial cable
B. Twisted-pair copper cable
C. Fiber optic cable
D. Wireless RF signals
,Answer: C
Rationale: Fiber optic cables transmit data using light, making them
immune to electromagnetic interference, which is crucial in industrial or
high-interference environments.
6. What is the purpose of a Digital Video Recorder (DVR) in a CCTV
system?
A. To amplify camera signals
B. To process and store video footage
C. To provide lighting for cameras
D. To convert analog video into audio
Answer: B
Rationale: DVRs receive video signals from cameras, compress the data,
and store recordings for playback and analysis.
7. Which of the following is a key advantage of IP cameras over analog
CCTV cameras?
A. They require coaxial cables
B. They provide higher resolution and network connectivity
C. They do not require power
D. They cannot be remotely accessed
Answer: B
Rationale: IP cameras transmit digital video over networks, offering higher
resolution, easier scalability, and remote access capabilities compared to
traditional analog cameras.
8. What does the term “backlight compensation” (BLC) in CCTV cameras
refer to?
A. Adjusting focus in low light
B. Enhancing video in bright backgrounds behind subjects
, C. Increasing infrared illumination
D. Zooming into a dark area
Answer: B
Rationale: BLC adjusts camera exposure to make subjects in front of strong
backlighting more visible, preventing silhouettes and loss of detail.
9. Which type of camera is most suitable for outdoor perimeter
monitoring under variable lighting conditions?
A. Dome camera
B. Fixed camera without infrared
C. Day/Night camera with IR capability
D. Bullet camera without weatherproofing
Answer: C
Rationale: Day/Night cameras can switch to infrared mode in low light,
providing consistent video quality in outdoor environments with varying
illumination.
10. In a CCTV system, what is the function of motion detection
software?
A. To rotate PTZ cameras automatically
B. To trigger recording only when movement occurs
C. To provide live video feeds
D. To power cameras efficiently
Answer: B
Rationale: Motion detection reduces storage needs by initiating recording
only when movement is detected, optimizing system efficiency.
11. What is the typical field of view (FOV) for a standard 3.6 mm
CCTV lens?
A. 15–20°
B. 45–50°
