Among a plurality of wireless access devices, regarding a wireless access device which is determined to be capable of communicating with a monitoring device, device identification information of the wireless access device is stored in an adjacent database. If there is device identification information which is not stored in the adjacent database, among device identification information stored in a registration database which stores device identification information of a wireless access device registered as a monitoring target of the monitoring device, whether or not communication is possible is determined again after a predetermined period of time has passed with respect to the wireless access device provided with the device identification information. On the other hand, if there is not, or after repeating a predetermined number of determinations, the device identification information stored in the adjacent information is copied into the registration database. |
