AXIS Q1755/-E - Troubleshooting

Poor rendering of H.264 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 H.264 tab in the AMC con-

 

trol 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.

 

 

Color saturation is different in H.264

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

and Motion JPEG

tation for more information.

 

 

Lower frame rate than expected

Reduce number of applications running on the client computer.

 

 

 

Limit the number of simultaneous viewers.

 

 

 

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

 

See also the online help.

 

 

 

Check in the AMC control panel applet (H.264 tab) that video processing is not

 

set to Decode only I frames.

 

 

 

Lower the image resolution.

rates, will affect the performance of the camera.

 

 

Poor performance

Poor performance may be caused by heavy network traffic, multiple users

 

accessing the unit, low performance clients, use of features such as Motion

 

Detection, Event handling, Image rotation other than 180 degrees.
