To determine the amount of motion the camera is currently detecting, use the

Motion sensitivity values correspond directly to activity values. Complete lack of motion is an
activity value of 0. Constant motion is an activity value of 100. Your activity value is less than
your motion sensitivity value when you're not moving; when you are moving, activity values
frequently exceed your motion sensitivity value.
