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 benets 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 Offse 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 specication. 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.
