A motion detector device includes a lamp assembly, a junction box assembly with a cylindrically shaped holding arm, a rotation assembly incorporating a sensor seat, a pyro-sensor and circuitry, and a lens assembly. The lens assembly can assume a semi-spherical or cylindrical shape. The lens assembly is integrally formed by a plurality of multifaceted lenses with pre-determined focuses constituting pre-determined focusing views. Each focusing view is defined for a range/distance and angle of detection. The lens assembly can be rotated to select a specific focusing view. The sensor seat is disposed at the focus of the selected focusing view to receive infrared radiation rays. The entire or half or portion of the lens assembly carries lenses making up the pre-determined focusing views.

Apparatus for passive infrared sensing of an intruder that discriminates between signals corresponding to a human target and much larger signals may include first and second IR sensors, at least a first amplifier having a first voltage operating range. The first amplifier may be connected to the first IR sensor and the apparatus may further include at least a second amplifier having a second voltage operating range. The second amplifier may also be connected to the first IR sensor and the apparatus may further include a comparator for comparing the respective outputs of the first and second amplifiers to predetermined values.

A thermal radiation detector for detecting thermal energy in multiple coverage zones is provided. The detector includes a heat sink support structure, a first thermal detection sensor coupled to the support structure and arranged to detect thermal energy in a first coverage zone, and a second thermal detection sensor coupled to the support structure for detecting thermal energy in a second coverage zone. The detector also has a shared optical lens coupled to the support structure and arranged to direct thermal energy from the first coverage zone to the first thermal detection sensor, and to direct thermal energy from the second coverage zone to the second thermal detection sensor. The detector is useful to detect heat emitting objects in a blind spot region of a vehicle.
