Abstract: A pyroelectric presence identification system includes focal plane array and a processor coupled to the focal plane array. The focal plane array includes a first image sensor and a plurality of second image sensors configured to convert radiant energy into an electrical signal. The processor is configured to control the focal plane array in a sleep mode wherein the first image sensor is utilized to detect gross motion of at least one presence and the plurality of second image sensors are de-energized.

Abstract: A passive infrared (PIR) sensor system, includes a PIR sensor configured to produce an output signal in response to receiving infrared (IR) radiation, an electronic shutter positionable in a field of view (FOV) of the PIR sensor, wherein the electronic shutter includes a liquid crystal (LC) material, wherein the electronic shutter includes a first state providing a first transmissivity of IR radiation through the electronic shutter and a second state providing a second transmissivity of IR radiation through the electronic shutter that is less than the first transmissivity, and a shutter actuator configured to apply an actuation signal to the electronic shutter to actuate the electronic shutter between the first state and the second state.
