ALC

The saturation (av-pk) slider configures the ALC level so that it controls mainly on scene
average level (slider position -15) or on scene peak level (slider position +15). Scene peak
level is useful for capturing images that contain car headlights.
Maximum gain [dB]
Adjust the decibels of maximum gain with the slider. The range is 6 to 72.
Exposure
Select the appropriate exposure speed.
Select Auto to allow the camera to set the optimum shutter speed automatically. The camera
tries to maintain the selected shutter speed as long as the light level of the scene permits.
Select Fixed to set a fixed shutter speed.
Min. frame rate
Select the minimum frame rate.
Default shutter
Select a default shutter speed. The default shutter improves the motion performance in auto
exposure mode.
Shutter time
Select the amount of time for the shutter to remain open.
Auto - the camera switches the IR cut-off filter on and off depending on the scene illumination
level.
Monochrome - the IR cut-off filter is removed, giving full IR sensitivity.
Color - the camera always produces a color signal regardless of light levels.
Night-to-day switchover
Adjust the slider to set the video level at which the camera in Auto mode switches from
monochrome to color operation (-15 to +15).
A low (negative) value means that the camera switches to color at a lower light level. A high
(positive) value means that the camera switches to color at a higher light level.
(The actual switch-over point might change automatically to avoid instable switching.)
Iris Priority (slider)
With this slider, you can 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.
