AXIS 212 PTZ - Troubleshooting
To enable the updating of video images in Microsoft Internet Explorer, set your browser to allow ActiveX con-
trols. Also, make sure that AXIS Media Control (AMC) component is installed on your workstation.
Configure your camera to use a Java applet for updating the video images under
Live View Config > Layout > Default Viewer for Internet Explorer. See the online help for more information.
Check the video image settings. See the online help on Video and Image Settings.
The camera requires sufficient light to deliver good image quality in zoomed in view. Better indoor lighting will
increase image quality.
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, motion detection, high-resolution images, high frame rates, etc, will reduce the
performance of the camera.
Poor performance may be caused by e.g. heavy network traffic, multiple users accessing the unit, low perfor-
mance clients, use of features such as Motion Detection, Event handling, Image rotation other than 180 degrees.
In Display Properties, configure your screen to show at least 65000 colors, i.e. at least 16-bit. Using only 16 or
256 colors will produce dithering artifacts in the image.
Limited click-in-image functionality in Quicktime, use the pan, tilt, zoom toolbars instead.
Lower the image resolution.
There is only limited space available for the upload of your own files. Try deleting existing files to free up space.
Motion detection is based upon changes in luminance in the image. This means that if there are sudden changes
in the lighting, motion detection may be triggered mistakenly. Lower the sensitivity setting to avoid problems
with luminance.
Check the sound card in the PC. Ensure that the mute button is not pressed and the volume settings are correct.
Check that the correct Audio Input source is selected under Setup > Audio > Source. Select Microphone for the
internal microphone or for a connected external microphone. Select Line for a connected line in source.
The volume of the microphone is either too high or too low. Change the volume for the microphone in the tool-
bar on the Live View page.
Too many users/clients connected to the camera may affect the sound quality adversely. Try limiting the number
of clients allowed to connect under Basic Configuration > Users.
Reduce the number of listeners and viewers and decrease the image resolution and compression.
It is recommended that the camera's time setting is synchronized with an NTP Server. This is enabled under Sys-
tem Options > Date & Time.
Check that the correct Audio Input source is selected under Setup > Audio > Source. Select Microphone for the
internal microphone or for a connected external microphone. Select Line for a connected line in source.
Audio break-up (stuttering audio) can be reduced using the Audio Buffer in AXIS Media Control. Right-click the
video image and select 'Settings' and 'Audio'. A higher audio buffering level will reduce audio break-up, but may
introduce a noticeable lag in audio transmission.
