Connecting a Video Iris Lens
The Cheetah 3G-SDI cameras are available with optional Video Iris lens.
A Video Iris lens uses a motor for adjusting the iris position when lighting conditions change. It
is equipped with an amplifier and operated by a video signal from the camera. Signals from the
camera's Hirose connector provide power and control the Video Iris through an external cable.
Imperx recommends using the
terminated with a female P-Iris/Video Iris plug. The cable drawing is shown on the page 23.
If your application requires assembling you own cable, please refer to the diagram below that
shows the Video Iris connections to the Hirose connector:
