Question 6

When focusing a camera with auto iris, focus will be more accurate if
A) Set during lowlight conditions, since the depth of field is shorter with a large iris opening.
B) Set during bright conditions, since the depth of field is shorter with a small iris opening.
C) Set during lowlight conditions, since the automatic gain control will increase image contrast.
D) Set during bright conditions, since image contrast will not be reduced by the automatic gain control.

Accepted Answer

In lowlight conditions, the iris opens wider, reducing the depth of field, making it easier to achieve precise focus.

Question 7

Which one of the following camera parameters may become a limiting factor for the camera in delivering full frame rate?
A) Noise reduction
B) Exposure time
C) Flicker-free mode
D) Aspect ratio 16:9

Accepted Answer

Exposure time is the time duration for which the camera's sensor is exposed to the incoming light. If this time is set to a high value, the camera will take longer to capture each frame, and as a result, the frame rate will decrease. Therefore, exposure time can become a limiting factor for the camera in delivering full frame rate. Noise reduction and flicker-free mode may affect the image quality, but they do not directly affect the frame rate. Aspect ratio 16:9 is a common aspect ratio used in video production and does not directly affect the camera's ability to deliver full frame rate.

Question 8

When using IR illuminators, which wavelengths would not produce any visible glow?
A) 650 nm
B) 750 nm
C) 850 nm
D) 940 nm

Accepted Answer

Wavelengths above 900 nm are beyond the visible spectrum and will not produce any visible glow. Therefore, option D (940 nm) is the best choice.

Question 9

When using the view area functionality, each view area has its own video stream and (Choose two)
A) Exposure control setting
B) Text overlay setting
C) User credentials
D) PTZ setting
E) Compression algorithm setting

Accepted Answer

Each view area can have its own PTZ setting and compression algorithm setting, but exposure control and text overlay settings are typically set for the entire camera rather than individual view areas. User credentials are also set at the camera level, rather than the view area level.

Question 10

Which of the following statements about multicast video streaming are true? (Choose three)
A) Multicast can help to save bandwidth in a network
B) Multicast can typically not be used to provide video over internet
C) Multicast uses TCP as transport protocol
D) Multicast extends the viewer capacity of a camera or an encoder from 10-20 to an unlimited number
E) RTSP streams are always sent through multicast

Accepted Answer

A) Multicast can help to save bandwidth in a network by sending a single stream to multiple clients instead of sending multiple streams to each client separately.
B) Multicast can typically not be used to provide video over internet due to the lack of multicast support in many internet routers.
C) Multicast uses UDP as transport protocol, not TCP.
D) Multicast extends the viewer capacity of a camera or an encoder from 10-20 to an unlimited number by allowing multiple viewers to receive the same stream simultaneously.
E) RTSP streams are not always sent through multicast, they can also be sent through unicast.
