Video Image Problems
	Image too dark or too light.	Check that the termination dip switch for the video source is set to the correct position. See

	Problems uploading own files	There is only limited space available for the upload of your own files. Try deleting one or more
		existing files, to free up space
	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 video server.
	Slow performance	Slow 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 handling, Image
		rotation.
Bad	snapshot images
	Display incorrectly configured on	In Display Properties, configure your display to show at least 65000 colors, i.e. at least 16-bit.

Incorrect exposure in images
	Incorrect line termination	If the AXIS 241QA/AXIS 241SA is to be connected in loop through with other equipment, dis-
		able the input termination by turning the corresponding DIP switch to OFF.
Problems with the MPEG-4 format

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 inappro-
	priate video object type can also affect the frame rate. See the online help for more informa-
	tion.
	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.
