Video Image Problems

 

 

 

 

 

Image too dark or too light.

See the help files on Video & Image Settings

 

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, hi-res images, high frame rate etc will reduce the performance of

 

 

the AXIS 231D/232D.

 

Slow performance

Slow performance may be caused by e.g. heavy network traffic, many users with access to unit,

 

 

low performing client, use of features such as 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.

 

 

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-

Lower the image resolution.

 

 

Reduce the number of applications running on the client computer.

Problem with hardware

Go to System Options > Maintenance > Dome Status and click Test to test the camera and

 

 

dome mechanics for errors. Contact Axis Customer Services if you receive an error message as

 

 

the result of this test.
