摘要：A thermopile far infrared radiation detection apparatus for crime prevention that is capable of detecting with certainty an intruder who is entering a monitoring space regardless of temperature changes of the space or how fast the intruder enters the
space. The detection apparatus utilizes three or more thermopiles to detect an intruder into the space and in which output difference between detection values outputted from a pair of said thermopiles is obtained, and then, the intruder is detected by the comparison between these output differences obtained from different pairs of the thermopiles.
