ABSTRACT:
The present invention relates to a thermally sensitive array device for detecting a presence of a target object in a surveillance area. The device comprises a plurality of at least two thermally sensitive sensors provided in an array arrangement, each thermally sensitive sensor being associated with one of a corresponding plurality of at least two surveillance spots comprised in the surveillance area. Each thermally sensitive sensor comprises a sensitive element adapted to absorb a portion of thermal infrared radiation emitted from one of said plurality of targets located inside the surveillance cone corresponding to the thermally sensitive sensor. The thermally sensitive sensor can be a thermopile, a bolometer, or any other type. Electronic circuits in each thermally sensitive sensor are adapted to measure a signal generated in the thermally sensitive sensor as a consequence of the temperatures of the target.
