Changes in luminance.
For additional assistance, please contact your reseller or see the support pages on
the Axis Website at www.axis.com/techsup
Color depth set incorrectly on clients. Set to 16-bit or 32-bit color.
If text overlays are blurred, or if there are other rendering problems, you may need to
enable Advanced Video Rendering. This is done on the MPEG-4 tab in the AMC control
panel applet.
Ensure that your graphics card is using the latest device driver. The latest drivers can
usually be downloaded from the manufacturer's web site.
If images are degrading, try decreasing the GOV length, see Advanced settings, on page
20.
Modify the settings for your graphics adapter. Please see the adapter's documentation
for more information.
Not all settings have an effect on the test image. For more information, see the help for
Image Settings.
Check that you are using an AXIS PS-K power supply.
Contact your Axis dealer.
See the Emergency Recovery Procedure, on page 51 above.
In Display Properties, configure your screen to show at least 65000 colors, i.e. at least
16-bit. Using only 16 or 256 colors will produce dithering artifacts in the image.
Lower the image resolution.
There is only limited space available for the upload of your own files. Try deleting one
or more existing files, to free up space.
This can occur when trying to use a larger image buffer than is actually available. Try
lowering the frame rate or the upload period.
The overlay may have been positioned incorrectly. Refer to the online help for informa-
tion on the limitations when using image overlays and privacy masks.
Motion detection is based upon changes in luminance in the image. This means that if
there are sudden changes in the lighting, motion detection may be mistakenly trig-
gered. Lower the sensitivity setting to avoid problems with luminance.
