Note:
If you still have a problem after reading this information, please contact your reseller or check the
FAQ on the AXIS 2120 product pages at the Axis Website at www.axis.com.
Possible causes
Focus has not been cor-
rectly adjusted.
No adapter fitted with
your C-type lens.
Video images may be
noisy if you are using the
AXIS 2120 in a very low
light environment.
The Display Properties
are incorrectly configured
for your desktop.
The camera is not
focused correctly.
ActiveX disabled.
Remedial actions
Referring to the on-line help, adjust the White Balance set-
ting and then try resetting the camera focus again using the
Focus Assistant, as described in Adjusting the Camera
Focus on page 44.
If you have previously replaced the supplied CS-type lens,
you may have inadvertently installed a C-type lens - without
the required adapter. See also page 47.
To solve this problem, you need more light. The perfor-
mance of the camera is best in 100 - 3000 lux.
You may wish to consider replacing the basic lens with a
more sensitive lens (Lower F-number), if the lighting in the
installation area cannot be improved.
Open the Display Properties in your desktop and configure
your display to show at least 65000 colors, i.e. at least
16-bit.
Note: Using only 16 or 256 colors on your computer will
produce dithering artifacts in the image.
Referring to the on-line help, adjust the White Balance set-
ting and then try resetting the camera focus again using the
Focus Assistant, as described in Adjusting the Camera
Focus on page 44.
If you are using Microsoft Internet Explorer, ensure that
ActiveX has not been disabled in the Internet Options
menu. Alternatively, use the Java Applet for viewing images.
