AXIS 221 - Replacing the lens 55

Replacing the lens

If the lens on the AXIS 221 needs to be replaced or if the camera was supplied without a lens, a new lens can be fitted quickly and easily. As the AXIS 221 is designed with a CS-mount, the lens supplied with your product can be replaced with any standard C or CS lens.

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 adapter for it to work with your AXIS 221. An adapter effectively moves the lens 5mm farther from the camera.

Removing and attaching the lens

1.Disconnect the power supply to the AXIS 221.

2.Disconnect the DC-Iris cable.

3.Unscrew the lens by turning it anti-clockwise.

4.Screw on the new lens until it is tight against the metal ring at the back.

5.Attach the DC-Iris cable to the camera and reconnect the power supply.

6.To focus the new lens, see Focusing, on page 9.

Note: In the unlikely case that the camera images are still blurred after focusing the lens, loosen the screw on the underside of the camera that holds the metal ring in place. Turn the metal ring in small increments until a sharp image is obtained. Tighten the screw on the underside of the camera.
