The projector is arranged to project a pattern onto the surface. At least one camera is arranged to capture sequential images of the surface. A processing unit is arranged to: receive the images from the at least one camera; detect the projected pattern in the received images; detect a change to at least one feature of the projected pattern in the received images; determine whether the detected change satisfies at least one predefined criterion for a subject exit event; and output a signal based on the determining.
