A system for controlling access to a secure room containing a plurality of safety deposit boxes comprises a motion detector, a biometric sensor, and a plurality of contact sensors, wherein each of the safety deposit boxes is associated with at least two contact sensors. The system includes a processor that is configured to unlock the gate when a plurality of access conditions are satisfied, which may include: collecting via the biometric sensor a biometric credential that matches a reference biometric credential in a user database; and determining the secure room is unoccupied based on at least a predetermined period of no motion detected by the at least one motion sensor. The processor may also be configured to generate a box-accessed event identifying one of the safety deposit boxes when all of the contact sensors associated with that safety deposit box are simultaneously open.
