Abstract
A swinging automatic door control system includes an activation sensor for acquiring images of a first area where the door swings when opening or closing, a presence sensor for detecting motion in a second area that fronts a non-swinging side of the door when said door is closed, and a controller for controlling the opening and closing of the door as a function of the acquired images of a first area and the detection of motion in the second area.
