SECTION ONE: QUESTIONS 1–100
1. Which factor has the most significant impact on the depth of field in a fixed-lens
surveillance camera?
,A. Bitrate control
B. Aperture size
C. Compression standard
D. Frame rate
🟢 B. Aperture size
🔴 Explanation: The aperture size directly controls the depth of field; a smaller aperture
(higher f-stop) increases the range of objects in focus, whereas a larger aperture narrows
it.
2. A technician needs to ensure that a camera remains accessible even if a primary
network switch fails. Which protocol should be implemented?
A. DHCP
B. SNMP
C. RSTP
D. FTP
🟢 C. RSTP
🔴 Explanation: Rapid Spanning Tree Protocol (RSTP) provides path redundancy and
prevents network loops, ensuring high availability in a networked surveillance system.
, 3. When configuring a camera for a high-contrast environment with both very bright
and very dark areas, which feature is most effective?
A. Digital Noise Reduction
B. Automatic Gain Control
C. Wide Dynamic Range
D. Backlight Compensation
🟢 C. Wide Dynamic Range
🔴 Explanation: Wide Dynamic Range (WDR) allows the camera to process multiple
exposures of the same scene to retain detail in both highlights and shadows.
4. Which of the following is a primary benefit of using H.265 compression over H.264 in
a surveillance system?
A. Improved color depth
B. Lower latency in live views
C. Reduced storage and bandwidth requirements
D. Increased field of view
🟢 C. Reduced storage and bandwidth requirements
🔴 Explanation: H.265 (HEVC) is more efficient than H.264, providing similar image
quality at approximately half the bitrate, which saves storage space.
, 5. What is the standard voltage provided by a PoE (802.3af) source to a powered
device?
A. 12V DC
B. 24V AC
C. 48V DC
D. 120V AC
🟢 C. 48V DC
🔴 Explanation: The IEEE 802.3af (PoE) standard typically operates at a nominal voltage
of 48V DC to power networked devices over Ethernet cabling.
6. A security site requires identification-level detail of individuals entering a gate.
According to EN 62676-4 standards, what is the minimum pixel density required?
A. 125 px/m
B. 250 px/m
C. 500 px/m
D. 100 px/m
🟢 B. 250 px/m
🔴 Explanation: The industry standard for "identification" of an unknown person requires
at least 250 pixels per meter (px/m) at the target location.
