Abstract
A motion detection system including a lens arranged to focus infrared radiation; a variably positionable optical attenuator arranged for variable positioning thereof opposite the focusing lens, operable for variably attenuating infrared radiation focused by the focusing lens, an extent and a magnitude of the variable attenuation being dependent on a position and on a set of physical characteristics of the variably positionable optical attenuator; a PIR sensor positioned opposite the focusing lens and the variably positionable optical attenuator, operable for sensing the focused and attenuated infrared radiation; and a human motion detection indication generator operable for ascertaining whether an intensity of infrared radiation sensed by the PIR sensor is above a human-generated infrared radiation detection threshold and, responsive thereto, for generating an indication of detection of human motion.
