To photograph a desired recording apparatus over a long time, when a plurality of recording apparatuses are connected via a network.

Photographic devices 21-24 are connected via a radio network 25. The photographic device 24 acquires and records photographic data. The photographic device 24 determines priority data on the photographic devices 21-24, based on the priority information transmitted to the other photographic devices 21-23 and the other priority information, transmitted from the other photographic devices 21-23. The photographic device 24 transfers photographic data to the other photographic device 23, based on the priority data of the other photographic devices 21-23, when the residual capacity of a recording part is less than a specified value that corresponds to the priority data of the photographic device 24. The present invention is applicable to, for example, photographic devices.
