Motion detection controls

Note These controls appear when you click the Up Arrow in the Motion Detection area and are available only viewing the primary (H.264) stream.

Enable Motion	Enables the motion detection feature and displays a grid over the video image.
Detection check box	When motion detection is enabled, the IP camera monitors activity in the video
	field areas that you specify. If activity at a defined level occurs in any of these
	areas, the IP camera generates an alert and takes the configured actions.
	To designate specific areas that the IP camera monitors for activity, select the
	areas by clicking each grid cell over the area. A red border indicates a selected
	area. To deselect an area, click it again.
	You can configure the following levels for areas that the IP camera monitors
	for activity:
	• Sensitivity—Designates the relative amount of activity that the IP camera
	must detect in the area before it generates an alert. A lower value means
	that more, or faster, activity is required to trigger an alert. A higher value
	means that less, or slower, activity is required. The default value is 80.
	• Threshold—Designates the percentage of pixels that the IP camera must
	identify as changed in the area before it generates an alert. The camera
	detects pixel changes at the defined sensitivity level. The default threshold
	value is 10.
	To configure sensitivity or threshold, right-click a grid cell that has a red
	border and then drag the Sensitivity and Threshold sliders to the desired
	values. Alternatively, enter a value from 1 through 100 for an option and press
	the Enter key. To reset the sensitivity and threshold to their default values of
	50, click Restore. These configuration settings affect the cell that you select.
	If the cell is part of a group of horizontally or vertically (but not diagonally)
	adjacent cells, the settings affect all cells in the group.
Full Screen check	Becomes available when you click check Enable Motion Detection check box.
box	Check the Full Screen check box to cause the IP camera to examine the entire
	video field for activity.
	You can configure the following items for this video field:
	• Sensitivity—Designates the relative amount of activity that the IP camera
	must detect in the area before it generates an alert. A lower value means
	that more, or faster, activity is required to trigger an alert. A higher value
	means that less, or slower, activity is required. The default value is 80.
	• Threshold—Designates the percentage of pixels that the IP camera must
	identify as changed in the area before it generates an alert. The camera
	monitors for pixel changes at the defined sensitivity level. The default
	threshold value is 10.
	To configure sensitivity or threshold, right-click anywhere in the video field
	border and then drag the Sensitivity and Threshold sliders to the desired
	values. Alternatively, enter a value from 1 through 100 for an option and press
	the Enter key. To reset the sensitivity and threshold to their default values of
	50, click Restore.
