AXIS 214 PTZ 42 Problems with the MPEG-4 format No MPEG-4 displayed in the client. 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. No multicast MPEG-4 displayed in Check with your network administrator that the multicast addresses used by the the client AXIS 214 PTZ are valid for your network. Check with your network administrator to see if there is a firewall preventing viewing. Multicast MPEG-4 only accessible by Check if your router supports multicasting, or if the router settings between the client and the server need to be local clients configured. The TTL (Time To Live) value may need to be increased. 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 usually be downloaded from the manufacturer's website. Color saturation is different in MPEG-4 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. 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. Image degeneration Decrease the GOV length, see the online help for more information. No images displayed in the Web interface Problem with AMC (Internet Explorer only) 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.

Problems uploading own files There is only limited space available for the upload of your own files. Try deleting one or more existing files, to free up space. Missing images in uploads This can occur when trying to use a larger image buffer than is actually available. Try lowering the frame rate or the upload period. Slow image update Configuring, e.g. pre-buffers, hi-res images, high frame rate etc will reduce the performance of the AXIS 214 PTZ. Slow performance 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. Bad snapshot images Display incorrectly configured on your In Display Properties, configure your display to show at least 65000 colors, i.e. at least 16-bit. workstation Using only 16 or 256 colors on your display will produce dithering artifacts in the image. Audio problems No audio Check that: No full-duplex function Poor performance Whining or screeching sound from speakers (feedback) • 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.
