AXIS 216FD/FD-V/MFD/MFD-V - Troubleshooting
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 from 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 usu-
ally be downloaded from the manufacturer's web site.
Modify the settings for your graphics adapter. Please see the adapter's documentation for
more information.
Reduce number of applications running on the client computer.
Limit the number of simultaneous viewers. This is done in System Options > Security >
Users.
Check with the system administrator that there is enough bandwidth available. See also
the online help.
Check in the AMC control panel applet (MPEG-4 tab) that video processing is not set to
Decode only I frames.
Lower the image resolution.
Make sure that Cyclic refresh under Setup > Video & Image > Advanced > MPEG-4
is disabled.
Decrease the GOV length, see the online help for more information.
Check that you are using an AXIS PS-L power supply.
Contact your Axis dealer.
See the Emergency Recovery Procedure above.
To enable the updating of video images in Microsoft Internet Explorer, set your browser to
allow ActiveX controls. Also, make sure that AXIS Media Control (AMC) component is
installed on your workstation.
Configure your camera to use a Java applet for updating the video images under
Live View Config > Layout > Default Viewer for Internet Explorer. See the online help for
more information.
Check the video image settings. See the online help on Video and Image Settings.
This can occur when trying to use a larger image buffer than is actually available. Try low-
ering the frame rate or the upload period.
Configuring, e.g. pre-buffers, motion detection, high-resolution images, high frame rates,
etc, will reduce the performance of the camera.
Poor performance may be caused by e.g. heavy network traffic, multiple users accessing
the unit, low performance clients, use of features such as Motion Detection, Event han-
dling, Image rotation other than 180 degrees.
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.
