A control apparatus in a crime prevention system comprises a communication
unit that notifies each managed apparatus that the application of power
to that apparatus is to be managed; a registration unit that, in response
to an answer to the notification from an apparatus, registers the
apparatus as a managed apparatus to indicate that the application of
power to the apparatus is to be managed; and a power control unit that
controls whether to apply power to the apparatus based on information
registered with the registration unit.
