Event - Foreign Object
Sensitivity: Click and move the slider control to the right to increase
sensitivity so that a relatively small movement will trigger the alarm. Move
the bar to the left to reduce the sensitivity of movement detection. Set up
an appropriate Sensitivity value will reduce the chance of false alarm. For
example, you can lower the Sensitivity to avoid the alarm being triggered
by a swinging tree in the breeze.
Interval: Click and move the slider control to the right to increase interval
time so that the alarm will only be triggered when the movement lasts
longer. Move to the left to reduce the interval time.
Region Definition: To detect Foreign Objects, you have to define a
detection zone and define the size of the object you want to detect.
Left-click and drag the mouse to draw the detection zone (Region 1).
After defining the detection zone, select Define object size, and then
left-click and drag the mouse to indicate the size of the object you want
to detect.
