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.
