The H.264 compression standard typically reduces bandwidth and storage usage compared to Motion JPEG in most situations.

Question 2

When zooming in on an object with varifocal or zoom lens, light sensitivity of the camera is
A) increasing
B) decreasing
C) the same
D) dependent on lens

Accepted Answer

When zooming in with a varifocal or zoom lens, the aperture of the lens decreases to maintain a constant exposure. This means that less light is getting through to the camera sensor, resulting in a decrease in light sensitivity (also known as ISO).

Question 3

What are the effects of changing the capture mode on an AXIS P1346 from 2048x1536 (3 MP) to 1920x1080 (HDTV)? (Choose two)
A) Minimum illumination decreases
B) Vertical angle of view decreases
C) Maximum frame rate decreases
D) Maximum frame rate increases
E) Motion blur increases

Accepted Answer

Choosing to change the capture mode from 2048x1536 to 1920x1080 will result in a decrease in the vertical angle of view, as the camera will capture a smaller area. However, it will also result in an increase in the maximum frame rate, as the camera will be able to process and transmit video more quickly with a lower resolution. None of the other options accurately reflect the effects of changing the capture mode.

Question 4

Which of the following general statements about illumination needs of PTZ cameras is true?
A) PTZ should not be used with IR light
B) The f-stop value of a lens will get higher if you zoom in
C) PTZ cameras in general tend to have lower f-stop value compared to fixed cameras
D) PTZ cameras should not be used with mixed IR and white light

Accepted Answer

As the zoom of a lens increases, the f-stop value also increases. Therefore, B is the correct statement. A, C, and D are incorrect. PTZ cameras can be used with IR light and may have lower or higher f-stop values compared to fixed cameras depending on the specific model. Mixed IR and white light can be used with PTZ cameras, but it may affect the image quality.

Question 5

A customer has strict requirements of 30 fps for recorded video. Which encoder choice would they select if they wanted three streams, per every one encoded channel, of D1 resolution video run at 30 fps in H.264?

Question 6

Adding network surveillance cameras to an existing Ethernet network
A) Is not recommended, since bandwidth demands from the surveillance video would likely congest the network.
B) Will benefit from using VLANs, to keep the surveillance video separate from other network traffic, reducing the risk for network congestion.
C) Will cause unacceptable video latency, due to the amount of UDP traffic taking precedence on the network.
D) Will benefit from establishing VPN connections to the cameras, reducing the risk of malicious users eavesdropping on the video.

Accepted Answer

Adding network surveillance cameras to an existing Ethernet network will benefit from using VLANs, to keep the surveillance video separate from other network traffic, reducing the risk for network congestion. This way, the surveillance video traffic can be prioritized and managed separately from other network traffic.

Question 7

A camera can deliver two full resolution 30 fps H.264 streams. The customer wants to have four H.264 streams at 30 fps, from the same product. How can this be achieved?
A) By changing the codec
B) By increasing the bandwidth
C) By decreasing the resolution
D) By increasing the frame rate

Accepted Answer

In order to achieve four H.264 streams at 30 fps, the resolution would need to be decreased to allow for more streams to be processed simultaneously without overloading the camera's capabilities. This trade-off between resolution and the number of streams is a common consideration in surveillance systems. Changing the codec, increasing bandwidth or frame rate, would not increase the number of streams without sacrificing some other aspect of the video quality or performance.
