Color depth set incorrectly on clients. Set to 16-bit or 32-bit color.
In the case of blurred text overlays, or other rendering problems, you may need to
enable Advanced Video Rendering from the MPEG-4/H.264 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.
Limit the number of simultaneous viewers.
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/H.264 tab) that video processing is
not set to Decode only I frames.
Lower the image resolution.
See the section General performance considerations, on page 40.
Decrease the GOV length, see the online help for more information.
Check that you are using the same indoor power supply that came with the product.
Contact your Axis dealer.
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 computer.
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
lowering the frame rate or the upload period.
Configuring pre-buffers, motion detection, high-resolution images, or high frame
rates, will affect the performance of the camera.
Poor performance may be caused by 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, that is, at
least 16-bit. Using only 16 or 256 colors will produce dithering artifacts in the image.
The overlay or privacy mask may have been positioned incorrectly or may be too
large. Refer to Overlay Image Requirements and Limitations in the online help for
more information.
Update your browser and Java to latest versions.
There is only limited space available for the upload of your own files. Try deleting
existing files to free up space.
Motion detection is based on changes in luminance in the image. This means that if
there are sudden changes in the lighting, motion detection may be triggered mistak-
enly. Lower the sensitivity setting to avoid problems with luminance.
