DATA ACQUISITION APPARATUS, DATA RECORDING SYSTEM, AND DATA RECORDING METHOD

摘要

There is provided a data acquisition apparatus capable of preventing a partial data missing and simplifying the configuration of an entire system. A data recording system (100) has a plurality of network cameras (10) and an administration server (30). The network cameras (10) notify the administration server (30) of the remaining memory capacity information of the network cameras (10). If there are any problems with data recordings, the network cameras request the administration server (30) to designate their substitute recording apparatus and send internal data to the substitute recording apparatus according to the information about the designated substitute recording apparatus. According to the substitute designation requests and the remaining memory capacity information, the administration server (30) designates the network cameras (10) having free spaces as the substitute recording apparatus and sends substitute recording apparatus information to the network cameras (10).
