To enable the updating of video images in Internet Explorer, set your browser to allow ActiveX
controls. Also, make sure that AXIS Media Control 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 Stream and Camera Settings.
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 pre-buffers, motion detection, high-resolution images, or high frame rates, will
affect the performance of the camera.
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 and image
rotation other than 180 degrees.
Check that the dome cover is clean.
Do not clean a dome cover that looks clean to the eye and never polish the surface. Excessive
cleaning can damage the surface.
For general cleaning of a dome cover it is recommended to use a non-abrasive, solvent-free
neutral soap or detergent with water and a soft cloth. Rinse well with clean lukewarm water.
Dry with a soft cloth to prevent water spotting.
Never use harsh detergents, gasoline, benzende or acetone etc. and avoid cleaning in direct sun-
light or at elevated temperatures.
In Display Properties, configure your screen to show at least 65000 colors, that is, at least
16-bit. Using only 16 or 256 colors will produce dithering artifacts in the image.
The overlay or privacy mask may have been positioned incorrectly or may be too large. Refer to
Overlay Image Settings in the online help for more information.
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 on 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 sensi-
tivity setting to avoid problems with luminance.
Check the sound card in the PC. Ensure that the mute button is not pressed and the volume set-
tings 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.
