Abstract: Key cabinet (AC1) for equipping an access control system (1) comprising a plurality of devices for reading data associated with personal identification means (EI), access control management means in particular comprising decision making means for controlling accesses and means for retaining a trace of the events occurring in this system, this cabinet (AC1) comprising means (Ci,j) adapted to receive a set of keys (CL) and means (TL) for controlling access to these receiving means. This cabinet (AC1) is connected to the access control system (1) by insertion between a reader device and its controller means. It furthermore comprises means (SC, CE1) for generating a virtual badge corresponding to any change of state, this virtual badge then being transferred to decision making means. Application in particular for equipping existing access control systems with key cabinets.

Abstract: The invention concerns a system for keeping watch over premises, comprising: elements (LA-LD) for controlling access to these premises; elements (V1-V3, P1-P8) for detecting intrusion or unauthorized presence in these premises, including perimeter detection elements (P1-P8) for detecting any intrusion in a predetermined perimeter around these premises, volumetric detection elements (V1-V3) for detecting any presence in predetermined zones of these premises. The access controlling elements (LA-LE) and the intrusion detecting elements (V1-V3, P1-P8) co-operate to put off the activation of some volumetric detection elements (V1-V3) for a predetermined exception delay whenever the access controlling elements (LA-LE) validate, during watch time, the presence of an authorized person or an access request from same. The invention is applicable to the watch and security of small buildings and professional and administrative offices.
