Video/Image problems - general
	No images in browser	To enable the updating of video images in Microsoft Internet Explorer, set your browser
	(Internet Explorer for Windows only)	to allow ActiveX controls. Also, make sure that AXIS Media Control (AMC) component
		is installed on your workstation.

	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 access-
		ing the unit, low performance clients, use of features such as Motion Detection, Event
		handling, .
	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 lens in the settings for Video & Image > Advanced. Focus the cam-
		era following the instructions on page 9, and then enable the DC-Iris lens.
	Images only shown in black & white.	Check the color level setting.
	Blurred images.	Refocus the camera. Check in the Video & Image > Advanced - Camera Settings that
		DC-Iris is set to Enabled. If the images are still blurred adjust the metal ring until the
		image is sharp,
	Rolling dark bands or flickering in	Try adjusting the Flicker-free exposure setting under advanced image settings. Note

Video/image problems - MPEG-4
	Lower frame rate than expected.	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 that you have a recent MPEG-4 decoder installed.
		Check in the AMC control panel applet (MPEG-4 tab) that video processing is not set to
		Decode only I frame.
		Lower the image resolution.
		Reduce the number of applications running on the client computer

	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. This is done on 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.

		tings, on page 16.
