Embodiments disclosed herein disclose a wireless charging system configured to generate and transmit power waves that, due to physical waveform characteristics, converge at a predetermined location in a transmission field to generate a pocket of energy. Receivers, associated with an electronic device being powered by the wireless charging system, may extract energy from these pocket of energy and then convert that energy into usable electric power for the electronic device associated with a receiver. The pocket of energy may manifest as a three-dimensional field (e.g., transmission field) where energy may be harvested by a receiver positioned within or nearby the pocket of energy. Video sensors capture actual video images of fields of view within the transmission field, and a processor identifies selected objects, selected events, and/or selected locations within the captured video images.
