AXIS 210/211/211A - Troubleshooting
Poor rendering of MPEG-4 images
Wrong color depth enabled in client. Check that 16 or 32 bit color depth is chosen in the client.
Blurry text overlay image or other prob-
lem with rendering.
Advanced Video Rendering may have to be enabled. Change this setting on the AMC con-
trol panel applet, MPEG-4 tab.
Graphics card driver. Check that the driver used is the latest available.
The Power indicator is not constantly lit
Faulty power supply. Check that you are using an AXIS PS-K power supply.
The Status and Network indicator LEDs are flashing red rapidly
Hardware failure. Contact your Axis dealer.

Problem with AMC.
(Internet Explorer only)
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.
Installation of additional ActiveX com-
ponent restricted or prohibited
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.
Video/Image problems, general
Image too dark or too light. Check the video image settings. See the online help on Video and Image Settings.
Missing images in uploads. This can occur when trying to use a larger image buffer than is actually available. Try
lowering the frame rate or the upload period.
Slow image update. Configuring, e.g. pre-buffers, motion detection, high-resolution images, high frame rates,
etc, will reduce the performance of the camera.
Poor performance. Poor performance may be caused by e.g. heavy network traffic, multiple users accessing
the unit, low performance clients, use of features such as Motion Detection, Event han-
dling, Image rotation other than 180 degrees.
Image gradually gets darker or lighter. When using the camera in locations lit by fluorescent lighting, check in the advanced
image settings that the Exposure control is set to Flicker-free.
Color saturation discrepancy between
Motion JPEG and MPEG-4.
Modify the settings on your graphics card.
Image loses focus often. Disable the DC-Iris lens (AXIS 211/211A only) in the settings for Video & Image >
Advanced. Focus the camera following the instructions on page 10. Then enable the
DC-Iris lens (AXIS 211/211A only).
Lower frame rate than expected when viewing MPEG-4
CPU usage too large. Reduce number of applications running on the client computer.
Not enough bandwidth available. Check with system administrator. Adjust settings of MPEG-4 profile, see MPEG-4 Set-
tings, on page 19.
Only decoding I-frames. Check settings in AMC control panel applet, MPEG-4 tab.
Large images Select lower imager resolution.
Image degenerating when viewing MPEG-4
GOV length too long Decrease the GOV length, see MPEG-4 Settings, on page 19.
Poor quality snapshot images
Screen incorrectly configured on your
workstation
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.
