Enable Motion 
Detection check box

Enables the motion detection feature and displays a grid over the video image. 

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 actions that are configured 
as described in the 

.

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 50.

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 50.

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.
