The invention relates to an electronic intrusion detection system for monitoring environments, comprising at least one electronic sensor (1a, 1b, 1c) responsive to movements occurring in said environment and adapted to modify at least one characteristic of its electrical output in response to the presence of a moving body in said environment; means (10a, 10b, 10c) for generating an alarm signal (ALARM) when said modification meets a predetermined condition; and transducer means (20a, 20b, 20c) for continuously converting said modification of the output from said electric sensor (1a, 1b, 1c) into a signal that can be perceived by a human being. An alarm control unit (30) connected to said alarm generating means (10a, 10b, 10c) and transducer means (20a, 20b, 20c) includes means for forwarding the signals to the surveillance personnel through a telephone line (43).

L'invention a trait à un système électronique de détection d'intrusion destiné à des environnements surveillés, comportant au moins un capteur électronique (1a, 1b, 1c) réagissant à des mouvements se produisant dans ledit environnement, et qui est adapté de façon à modifier au moins une caractéristique de son signal électrique de sortie en réponse à la présence d'un corps en mouvement dans ledit environnement; des moyens (10a, 10b, 10c) destinés à produire un signal d'alarme (ALARME) lorsque ladite modification remplit une condition préétablie; et des moyens de transducteur (20a, 20b, 20c) permettant de convertir en continu ladite modification du signal de sortie provenant dudit capteur électrique (1a, 1b, 1c) en un signal perceptible par un être humain. Une unité de commande (30) d'alarme connectée auxdits moyens (10a, 10b, 10c) producteurs d'alarme et de transducteur (20a, 20b, 20c) comporte un moyen destiné à envoyer les signaux au personnel de surveillance par une ligne téléphonique (43).
