1.
A technician installs cameras but notices poor image quality at longer distances; what is the most likely
issue affecting performance?
A. Excessive lighting
B. Incorrect lens focal length selection
C. Over-voltage supply
D. Excessive storage capacity
Answer: B
Rationale: Lens focal length determines field of view and clarity at distance; incorrect selection reduces
image quality.
2.
A CCTV system using IP cameras experiences lag during live viewing; what is the most probable cause?
A. Excessive camera resolution relative to bandwidth
B. Low ambient temperature
, Page 3 of 113
C. Excessive lighting
D. Incorrect mounting height
Answer: A
Rationale: High-resolution streams require more bandwidth, causing latency if network capacity is
insufficient.
3.
During installation, a camera shows interference lines; what is the most likely cause?
A. Proper grounding
B. Electromagnetic interference or poor cabling
C. High storage capacity
D. Correct lens type
Answer: B
Rationale: Interference often results from poor shielding or EMI affecting signal transmission.
4.

A system uses coaxial cable but signal loss occurs over long distances; what is the best solution?
A. Increase camera brightness
B. Use signal amplifiers or fiber optic transmission
C. Reduce storage size
D. Change monitor
Answer: B
Rationale: Signal degradation over long coax runs can be mitigated using amplifiers or fiber.
5.
A CCTV installer is asked to design coverage for a large outdoor parking lot; which camera type is most
suitable?
A. Fixed indoor dome only
B. PTZ cameras with zoom capability
C. Low-resolution webcams
D. Hidden microphones
Answer: B
Rationale: PTZ cameras allow wide-area monitoring and zooming for detail.
