Video/Image problems - general
No images in browser
(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 AXIS 225FD 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.
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 perfor-
mance of the camera.
Poor performance. Poor performance may be caused by e.g. heavy network traffic, multiple users accessing the unit, low performance cli-
ents, use of features such as Motion Detection, Event handling, Image rotation other than 180 degrees.
Image gradually gets darker or lighter. When using the AXIS 225FD in locations lit by fluorescent lighting, check in the advanced image settings that the Expo-
sure control is set to Flicker-free.
Image loses focus often. Disable the DC-Iris lens in the settings for Video & Image > Advanced. Focus the camera following the instructions on
page 8, and then enable the DC-Iris lens.
Images only shown in black & white. Check the color level setting.
Check the setting for the IR cut filter. Images are shown in color only when this filter is enabled, i.e. when set to yes or
auto.
Blurred images. Refocus the camera. Check in the Video & Image > Advanced - Camera Settings that DC-Iris is set to Enabled. If the
images are still blurred adjust the metal ring until the image is sharp.
Rolling dark bands or flickering in
image. Try adjusting the Flicker-free exposure setting under advanced image settings. Note that the 'Hold Current'/Manual set-
ting may cause unwanted effects.
Video/image problems - MPEG-4
Lower frame rate than expected. Check with the administrator that there is enough bandwidth available. Check also the settings for bit rate control, in
the
Video & Image > Advanced > MPEG-4 settings. Using an inappropriate video object type can also affect the frame
rate. See the online help for more information.
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.
Reduce the number of applications running on the client computer.
No MPEG-4 displayed in the
client. Check that the correct network interface is selected in the AMC control panel applet (network tab).
Check that the relevant MPEG-4 connection methods are enabled in the AMC control panel applet (network tab).
In the AMC control applet, select the MPEG-4 tab and click the button Set to default MPEG-4 decoder.
No multicast MPEG-4 displayed in the
client. Check with your network administrator that the multicast addresses used by the
AXIS 225FD are valid for your network.
Multicast MPEG-4 only accessible by
local clients. Check if your router supports multicasting, or if the router settings between the client and the server need to be config-
ured. The TTL (Time To Live) value may need to be increased.
Poor rendering of MPEG-4 images. 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.
This is done on the MPEG-4 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.
If images are degrading, try decreasing the GOV length, see Advanced Settings, on page 16.
Color saturation is different in MPEG-4
and Motion JPEG. Modify the settings for your graphics adapter. Please see the adapter's documentation for more information.
The test image does not display as expected
Image settings. Not all settings have an effect on the test image. For more information, see the help on Image Settings.
The Power indicator is not constantly lit
Faulty power supply. Check that you are using the correct power supply. See Power, on page 42 of Technical Specifications.
The Status and Network indicator LEDs are flashing red rapidly
Hardware failure. Contact your Axis dealer.
The Status indicator LED is flashing red and the camera is inaccessible
A firmware upgrade has been inter-
rupted or the firmware has otherwise
been damaged. See the Emergency Recovery Procedure above.
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 col-
ors will produce dithering artifacts in the image.
