How do I use a DC-iris lens with the Le-based Network cameras?
Network cameras support 4-wire DC-iris lenses (also called direct-drive lenses). To connect the DC-iris lens: Current-production cameras use the standard 4-conductor socket on the back of the camera case. To configure camera settings: In the camera web pages, click on the Admin Mode button. Next, click on the Exposure/Gain link. Select the Auto Iris check box with your mouse. You may also enter a value for the minimum exposure. If Auto Iris is enabled and the exposure time reaches the minimum exposure, then the camera will adjust the dc iris to achieve the requested luminance. Click the Save Settings link to retain your changes to camera settings.
