No images displayed in the Web interface

 

Problem with AMC

To enable the updating of images in Microsoft Internet Explorer, set your browser to allow

 

(Internet Explorer only)

ActiveX controls. Also, make sure that AXIS Media Control (AMC) component is installed on

 

 

your workstation.

 

Installation of additional ActiveX

Configure your Axis video server to use a Java applet for updating the images under

Video Image Problems

 

 

 

 

 

Image too dark or too light.

Check that the termination DIP switch for the video source is set to the correct position. See

 

 

also the online help on Video Source Settings

 

Black borders around the video

Adjust the X and/or Y offset, in the Video Source Settings. See the online help for information.

Problems uploading own files

There is only limited space available for the upload of your own files. Try deleting one or more

 

 

existing files, to free up space

 

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 video server.

 

Slow performance

Slow 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 handling, Image

 

 

rotation.

Bad

snapshot images

 

 

 

 

 

Display incorrectly configured on

In Display Properties, configure your display to show at least 65000 colors, i.e. at least 16-bit.

 

your workstation

Using only 16 or 256 colors on your display will produce dithering artifacts in the image.

 

 

Incorrect exposure in images

 

 

 

 

 

Incorrect line termination

If the Axis video server is to be connected in loop through with other equipment, disable the

 

 

input termination by turning the corresponding DIP switch to OFF.

Problems with the MPEG-4 format

 

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 inappro-

 

priate video object type can also affect the frame rate. See the online help for more informa-

 

tion.

 

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

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
