AXIS P3301/-V/AXIS P3304/-V - 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 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 H.264
and Motion JPEG
Modify the settings for your graphics adapter. Please see the adapter's documentation 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.
Why do I not get 30 frames per sec-
ond?
See the section General performance considerations, on page 50.
Image degeneration Decrease the GOV length, see the online help for more information.

Problem with AMC.
(Internet Explorer only)
To enable the updating of video images in Microsoft Internet Explorer, set your browser to
allow ActiveX controls. Also, make sure that AXIS Media Control (AMC) component is
installed on your workstation.
Installation of additional ActiveX
component restricted or prohibited

Live View Config > Layout > Default Viewer for Internet Explorer. See the online help for
more information.
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 pre-buffers, motion detection, high-resolution images, or high frame 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.
Poor recordings
Recording contains black images The GOV length is lower than the set frame rate. Change the GOV length to the same value
as the frame rate.
Poor quality snapshot images
Screen incorrectly configured on your
workstation
In Display Properties, configure your screen to show at least 65000 colors, that is, at least
16-bit. Using only 16 or 256 colors produces dithering artifacts in the image.
Overlay/Privacy mask is not displayed
Incorrect size or location of overlay or
privacy mask.
The overlay or privacy mask may have been positioned incorrectly or may be too large.
Refer to Overlay Image Requirements and Limitations in the online help for more infor-
mation.
