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.
Using the The Focus Assistant
Important!
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.
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.
