AXIS 216FD - Troubleshooting 47

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 from 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 usu-

 

ally be downloaded from the manufacturer's web site.

 

 

Color saturation is different in

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

MPEG-4 and Motion JPEG

more information.

 

 

Lower frame rate than expected

Reduce number of applications running on the client computer.

 

 

 

Check with the system administrator that there is enough bandwidth available. See also

 

the online help.

 

 

 

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.

 

 

Lost or poor images in pre-trigger

Make sure that Cyclic refresh under Setup > Video & Image > Advanced > MPEG-4

buffer (MPEG-4 video stream)

is disabled.

 

 

Image degeneration

Decrease the GOV length, see the online help for more information.

 

 

The Power indicator is not constantly lit

 

 

Faulty power supply

Check that you are using an AXIS PS-L power supply.

 

 

The Status and Network indicator LEDs

are flashing red rapidly

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 low-

 

ering 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.

 

 

Poor quality snapshot images
