A passive infrared motion detector discriminates between the motion of humans and pets in a premises. The motion detector includes an infrared sensor and a mirror for focusing infrared radiation from distinct fields of view. In one embodiment, a mask prevents infrared radiation from reaching the infrared sensor, and cut away regions on the surface of the mask allow selective passage of infrared radiation to the infrared sensor. In an alternative embodiment, the cylindrical mirror elements includes reflective and unreflective regions, which allow selective passage of infrared radiation to the infrared sensor. The cut away regions and the reflective regions are elongated to correspond to the shape of standing humans. As a result, the infrared radiation from animals only partially reaches the infrared sensor.
