1. A technician is installing a modern IP-based surveillance system in a
commercial facility. The client requests high-resolution video with
centralized storage and remote access. Which system architecture
best satisfies these requirements while minimizing cable runs and
allowing scalability?
A. Analog CCTV system with coaxial cabling and VCR recording
B. Network IP camera system using PoE switches and an NVR
C. Standalone DVR system with analog cameras and local storage only
D. Wireless analog transmitters connected to a single receiver hub
,Rationale: The correct answer is B because IP camera systems using Power
over Ethernet (PoE) and a Network Video Recorder (NVR) provide high-
resolution digital video, centralized storage, and scalable remote access
while reducing cabling complexity.
2. In a surveillance installation, a technician notices signal degradation
over long cable runs in a coaxial analog system. What is the most
effective method to maintain signal integrity without replacing the
entire system?
A. Increase camera brightness settings
B. Replace cameras with wireless models
C. Install signal amplifiers or video repeaters along the cable path
D. Reduce recording frame rate to improve transmission stability
Rationale: The correct answer is C because signal amplifiers or video
repeaters restore degraded analog video signals over long distances,
preserving image quality without requiring full system replacement.
3. A security system requires covert audio monitoring in compliance with
legal standards. Which factor is MOST critical before installing audio
surveillance equipment?
A. Camera resolution quality
B. Storage capacity of DVR system
,C. Applicable federal and state wiretapping and consent laws
D. Type of microphone used in the system
Rationale: The correct answer is C because audio surveillance is heavily
regulated, and compliance with wiretapping and consent laws is
mandatory before installation.
4. Which type of surveillance camera is MOST suitable for monitoring
large open areas such as parking lots with the ability to remotely
adjust viewing angles and zoom?
A. Fixed dome camera
B. Bullet camera
C. Pinhole camera
D. PTZ (Pan-Tilt-Zoom) camera
Rationale: The correct answer is D because PTZ cameras allow remote
control of direction and zoom, making them ideal for large, open
surveillance areas.
5. A technician is configuring a DVR system. What is the PRIMARY
function of a DVR in a surveillance setup?
A. Encrypt wireless camera signals
B. Provide internet connectivity for remote viewing
, C. Digitally record and store video from analog cameras
D. Amplify video signals for long-distance transmission
Rationale: The correct answer is C because a DVR (Digital Video Recorder)
converts and stores analog camera footage in digital format for later
review.
6. Which technology is MOST commonly used to prevent unauthorized
interception of wireless surveillance camera feeds?
A. Coaxial shielding
B. Fiber optic conversion
C. Infrared filtering
D. Encryption protocols such as WPA2/WPA3 or AES
Rationale: The correct answer is D because encryption protocols protect
wireless video transmissions from interception and unauthorized access.
7. In a surveillance system, motion detection is configured too
sensitively, causing frequent false alarms. What is the BEST
adjustment?
A. Increase camera resolution
B. Disable recording entirely
C. Adjust motion detection zones and sensitivity thresholds
D. Replace cameras with infrared models
