Abstract

Système pour épier la position d'un récepteur-retransmetteur dans une zone de surveillance, comprenant des premiers moyens pour émettre un premier signal à travers cette zone, un récepteur-retransmetteur qui agit en réponse à la réception de ce signal et émet au moins un signal de réponse qui est fonction du premier signal, et un récepteur pour recevoir ce signal de réponse. Le signal de réponse est fonction de la position du récepteur-retransmetteur dans la zone et il est prévu des moyens, commandé par le récepteur 16 sous la dépendance du signal de réponse, pour indiquer la position de récepteur-retransmetteur 18, dans la zone 14, ainsi qu'un dispositif d'alarme 17 déclenché par le récepteur. Ce système est destiné aux magasins et entrepôts pour déceler un enlèvement frauduleux.
