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.
See the section General performance considerations, on page 56.
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 lowering the frame rate
or the upload period.
Configuring, pre-buffers, motion detection, high-resolution images, high frame rates, etc, will reduce the
performance of the camera.
Poor performance may be caused by heavy network traffic, multiple users accessing the unit, low perfor-
mance 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.
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.
Motion detection is based upon changes in luminance in the image. This means that if there are sudden
changes in the lighting, motion detection may be triggered mistakenly. Lower the sensitivity setting to avoid
problems with luminance.
