need to enable Advanced Video Rendering from the H.264 tab in the AMC con-
trol 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 documen-
tation 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.

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.

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.
