Installation Manual
Description
Selects the video level range. A
positive value is more useful for low-
light conditions; a negative value is
more useful for very bright
conditions.
Some ALC adjustment may improve
scene content when Smart BLC is
enabled.
Adjusts the speed of the video level
control loop. For most scenes it
should remain at the default value.
AES (auto-shutter) - the camera
automatically sets the optimum
shutter speed.
FL - flickerless mode avoids
interference from light sources
(recommended for DC-iris lenses
only).
FIXED - allows a user defined shutter
speed.
In DEFAULT (AES) mode, the camera
tries to maintain the selected
shutter speed as long as the light
level of the scene is high enough.
In Fixed mode, selects shutter
speed.
