6. Return to your browser and review the picture quality. Repeat steps 4 & 5 only if you consider

Replacing the Lens

Since the AXIS 2120 is designed with a CS-mount, the lens supplied with your product can be
replaced with any standard C or CS lens typically used within the surveillance industry.
Note:
Although the lens supplied with your product can be directly replaced with any CS-type lens, a
C-type lens must be installed with an adaptor for it to work with your AXIS 2120. An adaptor
effectively moves the lens 5mm farther from the camera.
Follow the instructions below to replace the supplied DC-Iris lens with any C or CS type lens:
1. Unscrew the AXIS 2120 lens.
2. C-lens only: Attach the new lens to a C-CS Adapter.
3. Screw the new lens onto the AXIS 2120. If applicable, adjust the iris according to the
prevailing light conditions.
4. Referring to Focusing Procedure on page 46, adjust the camera focus.
5. Hit Refresh in your browser and monitor the results from the product Home Page.

Adjusting the DC-Iris Settings

If you choose to replace the lens supplied with your AXIS 2120 with something more specific to
your end-user application, the DC-Iris settings must be adjusted from their standard factory
default. In this case, you will need to modify the Exposure Control and other related settings for
your camera from the Image-Advanced page.
Use the information presented in the following tables to choose the appropriate settings for your
lens type.
Caution!
Exposing your camera to bright sunlight may cause permanent damage to the CCD if you:
• install and use a non-DC Iris lens with the product, or
• select anything other than DC-Iris in the Exposure Control settings of the Image - Advanced page.
Axis consequently advises extreme caution when changing the lens and/or when using the Image -
Advanced settings, as failure to do so may invalidate your product warranty.
