Abstract (en)
[origin: WO9828724A1] 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).
