Poor rendering of MPEG-4 images. 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 18.
Color saturation is different in MPEG-4
and Motion JPEG. Modify the settings for your graphics adapter. Please see the adapter's documentation
for more information.
The test image does not display as expected.
Image settings. Not all settings have an effect on the test image. For more information, see the help on
Image Settings.
The Power indicator is not constantly lit
Faulty power supply. Check that you are using an AXIS PS-K power supply.
The Status and Network indicator LEDs are flashing red rapidly
Hardware failure. Contact your Axis dealer.
The Status indicator LED is flashing red and the camera is inaccessible
A firmware upgrade has been inter-
rupted or the firmware has otherwise
been damaged. See the Emergency Recovery Procedure above.
Poor quality snapshot images
Screen incorrectly configured on your
workstation. 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.
Browser freezes
Netscape 7.x or Mozilla 1.4 (or later)
can sometimes freeze on a slow com-
puter. Lower the image resolution.
Problems uploading files
Limited space. There is only limited space available for the upload of your own files. Try deleting one
or more existing files, to free up space.
Missing images in uploads. This can occur when trying to use a larger image buffer than is actually available. Try
lowering the frame rate or the upload period.
Overlay is not displayed
Incorrect size or location of overlay. 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 triggers unexpectedly
Changes in luminance. 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.
