Abstract

L'invention concerne un système de surveillance permettant de réduire la charge imposée à des soignants ou à du personnel similaire, le système de surveillance, même si les notifications adressées à des soignants ou à du personnel similaire sont arrêtées dans certaines conditions, étant capable de réduire le désordre lorsque les notifications reprennent. Lorsque le système de surveillance envoie des informations d'événement sur une personne surveillée, qui transitent entre un dispositif de détection et un serveur de gestion, le serveur de gestion est configuré pour enregistrer les informations d'événement reçues et envoyer les informations d'événement à un terminal mobile. Lorsqu'un signal d'arrêt temporaire total est envoyé au serveur de gestion par un dispositif terminal fixe, le serveur de gestion exécute un processus d'arrêt temporaire total, dans lequel les informations d'événement reçues du dispositif de détection sont enregistrées, mais les informations d'événement ne sont pas envoyées au terminal mobile.
