Adjusting the Camera Focus
Important!
The AXIS 2100 features a replaceable CS-type lens that can be targeted for different applications.
Supporting rotational focus control, the lens must first be focused under normal quiescent
conditions to optimize the image quality for your camera.
Notes: •The lens rotates on a screw fitting and can be completely removed. If you do 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.
•The unit is supplied with the lens set in approximate focus position, with focus set to infinity.
The Focus Assistant
The Status Indicator, used in conjunction with the Focus Assistant, provides an immediate visual
display that will help you achieve a good basic level of focus at the point of camera installation.
This is particularly useful for remotely installed cameras, where the distance between the AXIS
2100 and your viewing workstation is often considerable.
Focus Quality
Once set to Focus Mode, the Status Indicator displays the following colors that represent a
predefined level of focus:
Rotational Focus Control
The lens provided with the AXIS 2100 has rotational focus control that allows the focal length of
the lens to be adjusted manually. The lens is used to establish the basic level of focus when the
image is stable, that is, when there is little or no movement. Rotate the lens clockwise for close
focus, or anti-clockwise for distant focus.
You will probably find that the Status Indicator displays green, indicating a good level of focus,
several times during the full traverse of the lens assembly. This is because several planes of focus
exist within the camera's normal field of view.
As an alternative to the focusing method described in this section, you can also adjust the camera’s focus
using the Administration Tools - for more information on this, please refer to your on-line help.
