Abstract

L'invention concerne un appareil de détection d'intrusion qui fonctionne par détection d'énergie infrarouge émise par le corps d'un intrus. Selon l'invention, un signal d'alarme est transmis lorsque le niveau des radiations détectées passe d'un niveau ambiant à un niveau de seuil. Un circuit sensible à la température règle le niveau de seuil afin que l'appareil air une sensibilité ou plage de détection relativement uniforme quelles que soient les variations de la température ambiante dans la zone protégée. Application à la protection contre les cambrioleurs.
