Iris Control
This menu is for advanced use only. It is factory set and should not require any alteration.
Under normal operating conditions no adjustment is needed, however in certain circumstances benefits
may be seen through minor adjustment for some DC drive lens.
Iris Response This will change the speed at which the Iris will respond to changes
in lighting conditions. The default is for a medium speed of response
however this can be set to react slower or faster to changes in the
scene as desirable to suit lens types and conditions.
Iris Offset Iris Offset is calibrated from the factory. However it may be necessary
to adjust this setting for different manufacturers lenses to allow for
differences in their specification. If the images from the camera are
pulsing in brightness, start by incrementing slowly until an improvement
is seen. If by doing this the pulsing is actually getting worse,decrement
instead to correct. If stability can not be reached then use the slower
Iris response setting.
