I assume it runs in low power mode most of the time, and is woken up by an RF signal from the dongle. It's _possible_ you could accomplish that via BLE from the phone, but maybe not.
Obviously the camera can't be on all the time, as I'm sure they're cutting the power budget pretty close as it is, given the size of the solar panel.
