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.
Maximum gain [dB]
Adjust the decibels of maximum gain with the slider.
Exposure
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.
P iris
The lens mode can be set to Standard or Manual.
– 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.
Day/night
Select the appropriate mode from the drop-down list.
– Auto - the device switches the IR cut-off filter on and off depending on the scene
illumination level.
– Color - the device always produces a color signal regardless of light levels.
– Monochrome - the IR cut-off filter is removed, giving full IR sensitivity.
Day-to-night switchover
Adjust the slider to set the video level at which the device in Automatic exposure mode
switches from color to monochrome operation.
A low (negative) value means that the device switches to monochrome at a lower light level. A
high (positive) value means that the device switches to monochrome at a higher light level.
