Problems uploading files
Limited space
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
usually be downloaded from the manufacturer's web site.
Modify the settings for your graphics adapter. Please see the adapter's documenta-
tion 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.
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.
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.
The camera requires sufficient light to deliver good image quality in zoomed in view.
Better indoor lighting will increase image quality.
This can occur when trying to use a larger image buffer than is actually available. Try
lowering the frame rate or the upload period.
Configuring, for example, pre-buffers, motion detection, high-resolution images, high
frame rates, etc, will reduce the performance of the camera.
Poor performance may be caused by for example, heavy network traffic, multiple
users accessing the unit, low performance clients, use of features such as Motion
Detection, Event handling, 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.
Limited click-in-image functionality in QuickTime, use the pan, tilt, zoom toolbars
instead.
Lower the image resolution.
There is only limited space available for the upload of your own files. Try deleting
existing files to free up space.
