2. Description of the Related Art In order to monitor the premises or the inside of a conventional substation and power plant, a monitoring person has been moving one after another to a place where monitoring is required, and performing monitoring. The substations and power stations were so large that it was difficult to move to monitor them. In addition, the operator may move to a high position in order to see the abnormality of the equipment, which is even more difficult. In addition, when there is an abnormality, a person who is on standby is required to be able to respond to an emergency or the like. In recent years, substations and power plants have become unmanned, and the burden of monitoring work has further increased due to the increase in monitoring work accompanying the unmanned operation.
