Adjusting the Camera Focus

The AXIS 2120 has a varifocal DC Iris lens that automatically regulates the amount of light entering the camera, to provide a wide-angle zoom with a minimal amount of distortion. Complete with a standard CS-mount, this supplied lens can also be replaced by any other lens conforming to the same standard.

Direct Focusing in Your Browser

Supporting rotational focus control, the AXIS 2120 can be targeted for different applications. With your video feed displayed on a local desktop, simply adjust the camera focus ring until you are satisfied with the focus.

However, for remote installations - where you cannot view your video images directly from your chosen point of installation - you can achieve a good level of camera focus by using the Focus Assistant, described later in this section.

Notes: •The text information printed on the lens assembly will

clearly define the focusing polarity (F, ∞ , and N) for the focus ring supplied with your unit. The camera focus is adjusted for either Far-focus (F, ∞ ) or Near-focus (N) by rotating the focus ring in the appropriate direction.

•The lens rotates on a screw fitting and can be completely removed. If you need to remove the lens, take care not to let any dust enter the lens or the camera window as this can adversely affect the quality of your live images.

Important!

The lens assembly illustrated below is NOT typical for all lens types.

Using the The Focus Assistant

Important!

As an alternative to the procedures described here, you can also enable and use the Focus Assistant directly from the Administration Tools. For more information on this, please refer to the on-line help.

Enabled using the Control Button (or from the Administration tools), the Focus Assistant works in conjunction with the Status Indicator to provide an onboard visual display for focusing your camera. With the Focus Assistant enabled, the Status Indicator displays Green when the camera is focused - which means that you can conveniently focus the AXIS 2120 without having to monitor the images in a desktop browser.
