Abstract

L'invention porte sur un système d'enregistrement d'image qui assure un coût moins élevé en énergie électrique et un cycle de vie plus long du produit. Un enregistreur (16) comprend une section de gestion de calendrier (168) pour gérer un calendrier d'une période pour activer/désactiver un affichage et enregistrement d'image en direct ou de n'importe quelle autre période, et une section de commande NW (161) pour arrêter l'alimentation électrique d'une caméra (10) conformément à un calendrier géré par la section de gestion de calendrier (168), arrêtant ainsi l'alimentation électrique de la caméra (10) lorsqu'un affichage ou enregistrement d'image en direct n'est pas requis après les heures d'ouverture et pendant les vacances ou analogue. En conséquence, des économies d'énergie électrique peuvent être réalisées pour abaisser le coût en énergie électrique. De plus, un cycle de vie de la caméra peut être allongé. En plus d'arrêter l'alimentation électrique de la caméra (10), une transition d'un décodeur (14) vers un mode d'économie d'énergie ou une transition d'un disque dur (HDD) (165) et d'un disque dur (166) vers un mode veille est rendue possible. Cela assure une réduction supplémentaire du coût en énergie électrique tout en allongeant les cycles de vie du décodeur et des disques durs.
