AXIS NETWORK VIDEO CERTIFICATION EXAMINATION
COMPLETE QUESTIONS AND DETAILED SOLUTIONS
LATEST UPDATE THIS YEAR JUST RELEASED
1.
A security designer must monitor a warehouse entrance where identification of
faces is more important than observing the entire surrounding area. Which design
consideration should receive the greatest priority?
A. Maximum horizontal field of view
B. Adequate pixel density at the identification area
C. Lowest possible camera resolution
D. Highest possible frame rate regardless of lighting
Answer: B
Rationale: Identification requires sufficient pixel density on the target area. A
wide field of view alone can spread available pixels too thinly for reliable facial
detail.
2.
A network camera produces acceptable daytime images but severe motion blur
whenever people move through a poorly illuminated corridor. Which adjustment
is most directly relevant?
A. Increase shutter speed while considering available light
B. Disable all image processing
,C. Reduce the camera's network bandwidth
D. Increase the Ethernet cable length
Answer: A
Rationale: A faster shutter can reduce motion blur, although it allows less light to
reach the sensor and may require other exposure adjustments.
3.
A surveillance system uses many cameras transmitting identical streams to
several monitoring clients. Which networking technology can reduce duplicated
traffic across the network?
A. Unicast
B. Multicast
C. NAT
D. ARP
Answer: B
Rationale: Multicast allows one transmitted stream to be delivered to multiple
subscribed receivers, potentially reducing network traffic compared with separate
unicast streams.
4.
,During camera selection, a customer requests excellent nighttime surveillance in
an area containing strong artificial lighting and occasional headlights. Which
camera capability should be investigated carefully?
A. Low-light performance and wide dynamic range
B. Maximum cable length only
C. Audio compression exclusively
D. Number of browser tabs supported
Answer: A
Rationale: Nighttime scenes with bright headlights and dark surroundings can
challenge exposure and dynamic range, making low-light performance and WDR
important considerations.
5.
A camera is installed behind glass, but nighttime infrared reflections are causing a
washed-out image. What is the most appropriate corrective consideration?
A. Increase network packet size
B. Prevent infrared reflections from returning toward the lens
C. Disable Ethernet negotiation
D. Reduce storage retention
Answer: B
Rationale: Infrared emitted toward nearby glass can reflect back into the lens.
Proper installation or suitable camera configuration can reduce this reflection
problem.
, 6.
A system designer wants to estimate how much storage a camera deployment
requires. Which combination is most directly relevant to the calculation?
A. Resolution, compression, frame rate, scene activity, and retention period
B. Camera color, mounting height, and monitor size
C. Lens brand and switch manufacturer only
D. DNS suffix and keyboard layout
Answer: A
Rationale: Storage requirements depend heavily on the amount of video
generated over time, which is influenced by resolution, frame rate, compression,
scene complexity, and retention.
7.
A camera is connected to a PoE switch but repeatedly restarts when infrared
illumination activates at night. What should be investigated first?
A. Whether available PoE power meets the camera's requirements
B. Whether the camera has enough storage locally
C. Whether the monitor uses HDMI
D. Whether the lens is varifocal
Answer: A
