Check that the correct network interface is selected in the AMC control panel applet (net-
work tab).
Check that the relevant MPEG-4 connection methods are enabled in the AMC control
panel applet (network tab).
In the AMC control applet, select the MPEG-4 tab and click the button Set to default
MPEG-4 decoder.
Check with your network administrator that the multicast addresses used by the
AXIS 213 are valid for your network.
Check with your network administrator to see if there is a firewall preventing viewing.
Check if your router supports multicasting, or if the router settings between the client
and the server need to be configured. The TTL (Time To Live) value may need to be
increased.
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 website.
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.
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.
Decrease the GOV length, see the online help for more information.
To enable the updating of images in Microsoft Internet Explorer for Windows, set your
Web browser to allow ActiveX controls. Also, make sure that AXIS Media Control (AMC)
component is installed on your workstation.
Configure your AXIS 213 to use a Java applet for updating the images under
Live View Config > Layout > Default Viewer for Internet Explorer. See help files for more
information.
See the help on Video & Image Settings.
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 low-
ering the frame rate or the upload period.
Configuring, e.g. pre-buffers, hi-res images, high frame rate etc will reduce the perfor-
mance of the AXIS 213.
Slow performance may be caused by e.g. heavy network traffic, many users with access to
unit, low performing client, use of features such as Event handling., Image rotation.
