Abstract: In an embodiment, a device comprises a solar panel configured to harvest power from energy emitted as light by an indoor light source, a camera, and a processor coupled to the solar panel and the camera. The processor can be configured to: receive at least some of the power harvested by the solar panel, capture an image via the camera, and transmit the image to a computing device. A battery can be coupled to the solar panel and the processor that can be configured to store at least some of the power harvested by the solar panel and provide at least some of the stored power to the processor.
