Check that the correct network interface is selected in the AMC control panel applet (network tab).
Check that the relevant MPEG-4 connection methods are enabled in the AMC control panel applet (network tab).
In the AMC control applet, select the MPEG-4 tab and click the button Set to default MPEG-4 decoder.
Check with your network administrator that the multicast addresses used by the
AXIS 214 PTZ are valid for your network.
Check with your network administrator to see if there is a firewall preventing viewing.
Check if your router supports multicasting, or if the router settings between the client and the server need to be
configured. The TTL (Time To Live) value may need to be increased.
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 Ren-
dering 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 usually be downloaded from
the manufacturer's website.
Modify the settings for your graphics adapter. Please see the adapter's documentation for more information.
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.
Decrease the GOV length, see the online help for more information.
To enable the updating of images in Microsoft Internet Explorer, set your Web browser to allow ActiveX controls.
Also, make sure that AXIS Media Control (AMC) component is installed on your workstation.
Configure your AXIS 214 PTZ to use a Java applet for updating the images under
Live View Config > Layout > Default Viewer for Internet Explorer. See help files for more information.
See the help on Video & Image Settings.
There is only limited space available for the upload of your own files. Try deleting one or more existing files, to free
up space.
This can occur when trying to use a larger image buffer than is actually available. Try lowering the frame rate or
the upload period.
Configuring, e.g. pre-buffers, hi-res images, high frame rate etc will reduce the performance of the AXIS 214 PTZ.
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 and image rotation.
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 sys-
tem 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.
