The “self-generating” camera can utilize both solar and mechanical power. On the top of the camera is a small solar panel that gathers sunlight in order to charge up. Hence “Sun” in the name.
For the “Cloud” part, we look to the side of the camera, on which there’s a convenient hand crank that lets you charge up the device even when there’s no sunlight to collect.
Finally, if you lack both sunlight and the motivation (or time) to crank out power by hand, there’s USB charging for juicing the camera up faster.
