Abstract (en)
[origin: WO9406104A1] An electro-magnetic security/surveillance equipment comprising transmitting means (1, 3) encircling and defining at least one area (1) in which at least one security device (7) is contained. Said security device (7) may be supplied with energy from a capacitor or other EMF accumulating means (9a) being sustained or charged by aforesaid transmitting means (1, 3) via "pick-up"/antenna means (8) and rectifying means (9a). Aforesaid security device (7) may be releasably attached to the secured objects by attachment means (10). If aforesaid security device (7) is removed, across the boundary of aforesaid secured area (1), or if the attachment means (10) are tempered with, a reaction from said security device (7) is caused, said reaction being registered by detecting means (4, 5) making it possible to register the state of said security device and thus establish a desired reaction (6) e.g. an alarm.
