AXIS NETWORK VIDEO FUNDAMENTALS VERIFIED EXAM
QUESTIONS AND ANSWERS - LATEST VERSION 2026/2027
1. What is the main advantage of a network camera over a traditional
analog CCTV camera?
A. It can only be viewed on a local monitor
B. It records video on magnetic tape
C. It requires a dedicated coaxial cable for every camera
D. It digitizes video inside the camera and sends it directly over an IP
network
D. It digitizes video inside the camera and sends it directly over an
IP network
A network camera has its own processor and network interface, so video
is compressed and streamed over standard IP infrastructure.
2. Which device is used to bring existing analog cameras into an IP-
based surveillance system?
A. Digital video recorder with no network port
B. Network switch
C. Video encoder
D. Media converter for fiber only
C. Video encoder
A video encoder converts the analog signal to digital, compresses it and
streams it over the network.

3. The image sensor in a network camera converts which of the
following into electrical signals?
A. Sound waves
B. Radio frequencies
C. Heat only
D. Light
D. Light
Each pixel on the sensor collects photons and converts them into an
electrical charge that is read out as image data.
4. Which sensor technology is used in the vast majority of modern
network cameras?
A. CCD
B. Bolometer
C. CMOS
D. Vidicon tube
C. CMOS
CMOS sensors offer low power use, fast readout and on-chip processing,
which is why they dominate modern IP cameras.
5. A thermal network camera typically uses which type of sensor?
A. Photomultiplier tube
B. CMOS visible-light sensor
C. CCD sensor
D. Microbolometer
D. Microbolometer
A microbolometer detects long-wave infrared radiation (heat) emitted by
objects, producing an image without visible light.
6. What does the term 'resolution' describe in network video?
A. The speed of the network connection
B. The number of pixels that make up the image
C. The distance the IR illuminator reaches
D. The amount of storage per camera
B. The number of pixels that make up the image
Resolution is expressed in pixels (width x height); more pixels allow finer
detail to be captured.

7. HDTV 1080p resolution corresponds to which pixel dimensions?
A. 3840 x 2160
B. 2560 x 1440
C. 1280 x 720
D. 1920 x 1080
D. 1920 x 1080
1080p, also called Full HD, is 1920 pixels wide by 1080 pixels high.
8. 4K UHD resolution in network cameras is commonly specified as:
A. 3840 x 2160
B. 2592 x 1944
C. 1920 x 1080
D. 4096 x 1080
A. 3840 x 2160
4K UHD is 3840 x 2160, four times the pixel count of 1080p.
9. What is the aspect ratio of HDTV video formats such as 720p and
1080p?
A. 1:1
B. 21:9
C. 4:3
D. 16:9
D. 16:9
HDTV standards use a 16:9 widescreen aspect ratio.
10. Corridor format, used for long narrow areas, is achieved by:
A. Switching the camera to thermal mode
B. Cropping the image to a square
C. Rotating the image 90 degrees to produce a 9:16 portrait view
D. Lowering the frame rate
C. Rotating the image 90 degrees to produce a 9:16 portrait view
Mounting the camera or sensor rotated and turning the image 90 degrees
gives a tall view that fits hallways and aisles.

11. What does the letter 'p' mean in 720p or 1080p?
A. Pan
B. Pixel
C. Packet
D. Progressive scan
D. Progressive scan
Progressive scan captures every line of the frame at once, avoiding the
combing effect seen with interlaced video.
12. Why does progressive scan produce better images of moving
objects than interlaced scan?
A. It uses a lower resolution
B. All lines of a frame are captured at the same instant
C. It uses two separate sensors
D. It removes all motion from the scene
B. All lines of a frame are captured at the same instant
Interlaced video captures odd and even lines at different moments,
causing jagged edges on motion; progressive avoids this.
13. Frame rate is measured in:
A. Degrees
B. Bits per pixel
C. Lux
D. Frames per second (fps)
D. Frames per second (fps)
Frame rate is the number of complete images captured or displayed every
second.
14. Which statement about frame rate and bandwidth is correct?
A. Higher frame rates generally increase bandwidth and storage
requirements
B. Frame rate has no effect on bandwidth
C. Frame rate only affects audio
D. Lower frame rates always increase bandwidth
A. Higher frame rates generally increase bandwidth and storage
requirements
More frames per second means more data to transmit and store, although
compression reduces the impact for static scenes.
