AXIS 210/211 - Troubleshooting 47

Video/Image problems, general
	Image too dark or too light.	Check the video image settings. See the online help on Video and Image Settings.
	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, motion detection, high-resolution images, high frame rates,
		etc, will reduce the performance of the camera.
	Poor performance.	Poor performance may be caused by e.g. heavy network traffic, multiple users accessing
		the unit, low performance clients, use of features such as Motion Detection, Event han-
		dling, Image rotation other than 180 degrees.
	Image gradually gets darker or lighter.	When using the camera in locations lit by fluorescent lighting, check in the advanced
		image settings that the Exposure control is set to Flicker-free.
	Image loses focus often.	Disable the DC-Iris (AXIS 211 only) in the settings for Video & Image > Advanced.
		focus the camera, following the instructions on page 11. Then enable the DC-Iris again.
Problems with the MPEG-4 format
	Lower frame rate than expected.	Insufficient light will reduce the frame rate. Adjust the low light behavior settings in the
		Video & Image > Advanced > Camera settings.
		Check with the administrator that there is enough bandwidth available. Check also the
		settings for bit rate control, in the Video & Image > Advanced > MPEG-4settings.
		Using an inappropriate video object type can also affect the frame rate. See the online
		help for more information.
		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.
		Reduce the number of applications running on the client computer.

		Check that the relevant MPEG-4 connection methods are enabled in the AMC control
		panel applet (network tab).

		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 web site.
