Iris Control
The cameras have an auto-iris circuit that sets the luminance level of the scene by adjusting
the camera iris position. During initial camera setup, the camera AGC should be turned off,
and the shutter speed fixed to the slowest setting. The auto-iris control can then be manually
adjusted using a small screwdriver to adjust the iris adjust screw to the rear of the camera to
obtain the desired level of brightness for the scene. Once adjusted, the AGC can then be re-
enabled.
• The luminance of the video can be varied by:
• The manual adjustment of the iris.
• The Brightness setting in the Video menu (if AGC disabled).
• The Shutter Speed setting in the Video menu.
Profiles
The active profile can be changed automatically based on events and the criteria defined in
this menu.
Use this menu to configure which events action which profile. When profiles conflict, i.e. two
different profiles are activated at the same time, the profile with the highest priority is chosen,
