AUTO IRIS
Auto iris is the lens function that automatically opens and closes the iris in response to changing
light conditions.
Program the auto iris to operate automatically or at a user-defined level.
OFF Auto iris is disabled, and control is always manual.
AUTO (default) The iris is adjusted automatically to produce a constant video
output as determined by the Auto Iris Level setting.
NOTE: If auto iris is in the auto mode, it will remain that way until the iris is manually opened
or closed. The dome will return to auto mode when it is panned or tilted more than 15 degrees.
Auto Iris Level
Auto Iris Level is the numeric value the auto iris uses to maintain the brightness level of the
camera. Increase the value to brighten the scene. Decrease the level to darken the scene. This
setting can be adjusted if the video level in the auto iris mode is too bright or too dark.
NOTE: If backlight compensation is ON, decrease the Auto Iris Level setting.
Auto Iris Peak
Increasing the peak value will cause the auto iris circuit to react more to highlights or “peaks” in
the picture. Decreasing this value will cause it to use the average video level to adjust the iris.
*This setting only applies to Pressurized
Spectra III dome systems with software
version 1.27 or higher.
