Abstract: A motion detector camera is configured to differentiate between an object or objects passing through the field of view of the camera and an object or objects approaching the sensor. In one example, motion is detected with a camera configured to identify and selectively filter specific directions of motion. The motion detector compares pixel changes, corresponding to the basic area or size of the object, from frame to frame, and detects the amount of increase in change or decrease in change. An increasing change in the area or size of an object indicates that an object is approaching, and a decreasing change in the area or size of an object indicates that an object that is receding.
