Appendix B - Auto Iris
General
The CCD (charged coupled device) supplied with the AXIS 200+ can become permanently
damaged if the camera lens is exposed to too much direct sunlight or halogen light. In extreme and
outdoor environments such as these, it recommended that the AXIS 200+ is fitted with an Auto Iris
lens. An Auto Iris lens also improves image quality during high and low light conditions.
The AXIS 200+ is designed with a CS-mount which means that the lens supplied with your
product can be replaced with any standard CS lens, typically used within the surveillance industry.
Notes:
A C-mount lens will also work with the AXIS 200+ Camera Server if used with an adaptor that
effectively provides a spacer with two female 1-32 threads and moves a lens 5mm farther from
the camera.
DC type lenses are not supported. Use an Auto Iris type lens.
An Auto Iris lens can be distinguished from a DC-type lens by the LEVEL and ALC adjustment
screws. These screws are not fitted to DC-type lenses. An Auto Iris lens additionally uses the
video signal as feedback to the lens.
Connecting an Auto Iris Lens to the AXIS 200+
• Red wire connects to PIN # 5 power source 12 V DC (+)
• White wire connects to pin # 3 video signal
