the observed area, the higher the value that must be selected.

generating an alarm. This helps prevent false alarms from events such as a bird
flying across the surveillance area.

Alarm area size:
You can specify the number of sensor fields that a moving object must cover to
generate an alarm. This is to prevent objects that are too small from triggering an
alarm.
The minimum setting is "1". This corresponds to one sensor field.
– Select the desired value by dragging the scroll thumb to the desired position.

the preview frame on the right side of the page. Sensor fields that are currently
reacting to motion are marked red on the video image. Inactive sensor fields are
marked green.
