Bosch Security Systems Installation and Operation Manual AR18-10-B006 | v1.1 | 2010.06
A negative value gives more priority to average light levels; a
positive value gives more priority to peak light levels. Video iris
lens: choose an average level for best results (peak settings
may cause oscillations).
Speed
Adjust the speed of the video level control loop (Slow, Medium,
or Fast). For most scenes it should remain at the default value.
9.6.3 Shutter/AGC
Shutter
– Fixed — allows a user-defined shutter speed.
– AES (auto-shutter) — the camera automatically sets the
optimum shutter speed. The camera tries to maintain the
selected default shutter speed as long as the light level of
the scene permits.
– FL — flickerless mode avoids interference from light
sources (recommended for use with video iris or DC iris
lenses only).
Default shutter / Fixed shutter
Select the shutter speed (1/60 [1/50], 1/100, 1/120, 1/250, 1/
500, 1/1000, 1/2000, 1/5000, 1/10K) for the default (AES) or
fixed value.
In 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, select the shutter speed.
Actual shutter
Displays the actual shutter value from the camera to help
compare lighting levels and optimum shutter speed during set-
up.
Sensitivity up
Selects the factor by which the sensitivity of the camera is
increased (OFF, 2x, 3x, etc. to a maximum of 10x).
