from speakers (feedback)
For additional assistance, please contact your reseller or check the product's
support pages on the Axis Website at http://www.axis.com/techsup
In Display Properties, configure your display to show at least 65000 colors, i.e. at least
16-bit.
Using only 16 or 256 colors on your display will produce dithering artifacts in the image.
Check that:
• PC sound card, speakers and microphone are correctly connected
• the Mute button is not pressed
• the volume in and volume out settings are correct
• all cabling is connected
• the value of the Post Content Length in your proxy server is 1MB or more. You may
need to contact your system administrator to do this.
Incorrect configuration. Check the setting in the camera's Setup pages.
Sound card does not support full-duplex. For information on how to check if your sound
card supports full-duplex, please visit www.axis.com and see the support section for Axis
camera products.
Too many users/clients connected. Try limiting the number of clients allowed to connect.
Low bandwidth. Reduce the Speed setting on the Audio settings page. Setting lower speed
will reduce any break-up in the sound, but will also increase the transmission delay. If
running in Full-Duplex mode, try switching to Half-Duplex mode.
Poor positioning of speakers and/or microphone. Relocate the speakers or microphone so
that they do not point towards each other, and/or lower the volume.
