To enable the updating of video images in Microsoft Internet Explorer, set your browser to allow ActiveX controls. Also,

 

(Internet Explorer only)

make sure that AXIS Media Control (AMC) component is installed on your workstation.

Configure your AXIS 225FD to use a Java applet for updating the video images under

 

ponent restricted or prohibited.

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

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-4settings. 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 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

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

Modify the settings for your graphics adapter. Please see the adapter's documentation for more information.
