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.
Bad focus Focus has not been correctly
adjusted. Referring to the on-line help, adjust the White Balance setting and
then try resetting the camera focus again using the Focus Assis-
tant, as described in Adjusting the Camera Focus on page 39.
No adapter fitted with your
C-type lens. 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 42.
Noisy images. Video images may be noisy if
you are using the AXIS 2120
in a very low light environ-
ment.
To solve this problem, you need more light. The performance of the
camera is best in 100 - 3000 lux.
You may wish to consider replacing the basic lens with a more sen-
sitive lens (Lower F-number), if the lighting in the installation area
cannot be improved.
Bad quality images. The Display Properties are
incorrectly configured for
your desktop.
Open the Display Properties in your desktop and configure your dis-
play 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.
The camera is not focused
correctly. Referring to the on-line help, adjust the White Balance setting and
then try resetting the camera focus again using the Focus Assis-
tant, as described in Adjusting the Camera Focus on page 39.
No images available in your
browser application. ActiveX disabled. If you are using Microsoft Internet Explorer, ensure that ActiveX
has not been disabled. Alternatively, use the Java Applet for view-
ing images.
