Apparatus for monitoring opening of sealed enclosures, especially, but not exclusively, sealed containers containing goods-in-transit, such as goods vehicles, maritime containers or transport containers of the kind carried by tractor-trailers, ships, trains or aeroplanes comprises a radio receiver unit having at least one antenna for reception of radio signals. The receiver unit is housed within the enclosure and operates to scan a predetermined band of radio frequencies, periodically or continuously, and detect a sudden change in signal level. When it detects such a change in radio signal level, the receiver generates an alarm signal. Alternatively, the receiver may detect the difference between internal and external radio signal levels and determine the container to have been opened if the difference is less than a preset threshold.

Dispositif permettant de contrôler l'ouverture de contenants scellés Vs en particulier, mais non exclusivement, au transport de marchandises par véhicule articulé, navire, train ou avion. Comprend un récepteur radio ayant au moins une antenne pour la réception de signaux radio. Le récepteur est logé dans le contenant et permet de balayer une bande de fréquences radioélectriques prédéterminée, de façon périodique ou continue, et de détecter une modification soudaine du niveau du signal. Lorsqu'il détecte une telle modification, le récepteur produit un signal d'alarme. Ou encore, il peut détecter la différence entre les niveaux de signaux radio internes et externes et déterminer qu'il y a ouverture du contenant si cette différence est inférieure à un seuil préétabli.
