ALC level
Adjust the video output level.
Select the range within which the ALC will operate. A positive value is more useful for low-
light conditions; a negative value is more useful for very bright conditions.
Priority - dark vs. bright
Use the slider to configure the ALC to prioritize either darker spots in the scene (scene
average) or brighter spots in the scene (scene peak). For example, prioritizing the control of
bright spots in a scene is useful for capturing images that contain sources of illumination, such
as car headlights.
ALC speed
Select the speed of the video level control loop from the dropdown list.
Maximum gain [dB]
Adjust the decibels of maximum gain with the slider.
Exposure
Select the appropriate exposure speed.

–
Maximum shutter [s]
Select a value in this field as the maximum speed of the shutter when the camera is in
Automatic exposure mode. The limit on the shutter speeds improves the motion performance.
Default shutter [s]
Select a default shutter speed. The default shutter improves the motion performance in auto
exposure mode.
Fixed shutter [s]
Select the Fixed shutter [s] for fixed exposure. (The values available depend on the value set
for the ALC mode).
P iris
The lens mode can be set to Standard or Manual.

–
Iris priority - open vs. closed
Use the slider to adjust the iris opening to the specific requirements of the scene.
An open iris increases local sharpness.
A closed iris increases depth of field, which allows you to keep objects of interest in focus.
In scenes where a change of the iris opening affects the gain, closing the iris causes more
video noise and increases bandwidth. Increased motion blur may also occur when the iris is
more closed.

Standard
Select Automatic exposure to allow the device to set the optimum shutter speed
automatically. The device tries to maintain the default shutter speed as long as the light
level of the scene permits.
Select Fixed exposure to set a fixed shutter speed.
Select the shutter speed for fixed exposure.
In the Standard mode, the F-stop of the lens is adjusted automatically for best
performance.
In the Manual mode, the precise F-stop of the lens can be selected with the slider.
