sensitivity to trigger motion detection. You can configure up to four areas. The

alarm. The lower the threshold setting, the easier it is to trigger a motion detection
alarm. You can configure up to four areas. The sensitivity ranges from 0 to 100. We
recommend that you choose a sensitivity between 5 to 50.
