Abstract

L'invention concerne un dispositif électronique de détection de vol destiné à surveiller de larges passages. Le dispositif comporte une antenne d'émission et une antenne de réception disposées respectivement sur le sol et sur le plafond d'un passage surveillé. Ces antennes comportent des conducteurs dans les directions longitudinale et transversale du passage, et sont décalées les unes par rapport aux autres de manière à assurer la sensibilité du dispositif le long de différents trajets de sortie et avec des plans d'orientation différents des circuits résonnants à détecter. L'invention s'applique notamment à la surveillance des magasins de détail.
