The distance between the wireless communication unit 101 and the fixed system 20 may be described. If direct communication is not possible according to the conventional wireless communication technology such as communication through a repeater or satellite.

The control system may be an unmanned management form in which the manager is resident or operated, or takes an emergency contact to the manager when it is determined to be a fire using an automatic discrimination system for a video signal, but this is not a feature of the present invention. Descriptions and limitations are omitted.
