– Fluorescent 50 Hz
– Fluorescent 60 Hz
– Outdoor
ALC level
Adjust the video output level (-15 to 0 to +15).
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.
Saturation (av-pk)
(only present on some cameras)
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 level
(only present on some cameras)
To set the Maximum gain level, select Low, Medium or High
from the drop-down box.
Exposure/frame rate
Automatic exposure
Select to let the camera automatically set the optimum shutter
speed. The camera tries to maintain the selected shutter speed
as long as the light level of the scene permits.
4 Select the minimum frame rate for automatic exposure.
(The values available depend on the value set for the Base
frame rate in the Installer Menu.)
4 Select a default shutter speed. The default shutter
improves the motion performance in auto exposure mode.
