Poor quality snapshot images
Screen incorrectly configured on your

Overlay/Privacy mask is not displayed
Incorrect size or location of overlay or
privacy mask.
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/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 46.
Decrease the GOV length, see the online help for more information.
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, 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.
If the view in front of the camera changes during adjustment (i.e., if a finger or other
object is placed in front of the lens, lighting conditions change, or if the camera is
moved), the process of using the focus assistant will either need to be restarted, or
the camera will need to be adjusted manually.
If the control button is not released within two seconds, dynamic DNS is enabled
instead of the Focus Assistant.
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.
