The alarm may be used as a warning sound, and may be used as a warning light.

According to the above embodiment, the contactless power supply device 20 can fix the photographing device 10 to the glass 2 via the fixed coil 23 At this time, electric power is supplied to the power receiving coil 14 via the power feeding coil 22, and the monitoring camera 13 is mobilized. As a result, the installation of the surveillance camera 13 that does not need to be performed in the past is also provided, and the power cable of the surveillance camera 13 is not required to be guided. Accordingly, it is possible to particularly improve the setting workability of the monitoring camera 13.

Further, since the fixed coil 23 uses the same electric power as that supplied to the power feeding coil 22, the image pickup apparatus 10 can be efficiently sucked and held.
