Poor rendering of MPEG-4 images.
Color saturation is different in MPEG-4
and Motion JPEG.
The test image does not display as expected.
Image settings.
The Power indicator is not constantly lit
Faulty power supply.
The Status and Network indicator LEDs are flashing red rapidly
Hardware failure.
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.
Poor quality snapshot images
Screen incorrectly configured on your
workstation.
Browser freezes
Netscape 7.x or Mozilla 1.4 (or later)
can sometimes freeze on a slow com-
puter.
Problems uploading files
Limited space.
Missing images in uploads.
Overlay is not displayed
Incorrect size or location of overlay.
Motion Detection triggers unexpectedly
Changes in luminance.
No audio
Incorrect setup.
Post Content Length in proxy server.
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
23.
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 on
Image Settings.
Check that you are using an AXIS PS-K power supply.
Contact your Axis dealer.
See the Emergency Recovery Procedure 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 triggered.
Lower the sensitivity setting to avoid problems with luminance.
Check that the sound card in the PC and the connections to the speaker and microphone
are working. Ensure that the mute button is not pressed and the volume settings are cor-
rect. Ensure that full-duplex is selected if you want to have two way audio communica-
tion.
The Post Content Length set in the proxy server is too low. Set the value of the Post Con-
tent Length in your proxy server to 1MB or more. You may need to contact your system
administrator to do this.
