Abstract

La présente invention concerne un système de surveillance qui comporte : un dispositif d'analyse/de banque d'images (10) qui conserve et analyse des données d'images capturées par des caméras (11), et qui, si une anomalie est détectée, génère un signal d'alarme incluant l'heure de la survenue de l'anomalie ; un dispositif de communication (30) qui, lorsqu'il reçoit le signal d'alarme, reçoit, du dispositif d'analyse/de banque d'images (10) et en tant que données d'images enregistrées, des données d'images qui sont incluses dans les données d'images conservées dans le dispositif d'analyse/de banque d'images (10), et qui ont été capturées pendant des périodes définies de temps précédant et suivant immédiatement l'heure de la survenue de l'anomalie ; et un serveur (40) qui reçoit le signal d'alarme et les données d'images enregistrées du dispositif de communication (30), transmet un courrier de notification de détection d'anomalie à un terminal mobile (50) sur la base du signal d'alarme reçu, et conserve les données d'images enregistrées reçues, le terminal mobile (50) communiquant avec le serveur (40) en réponse au courrier de notification de détection d'anomalie reçu du serveur (40), et recevant les données d'images enregistrées du serveur (40). De cette manière, une image capturée lorsqu'une anomalie est survenue peut être consultée avec précision depuis un lieu distant au moyen d'une petite quantité de communications de données et d'une petite capacité de banque de données.
