Abstract: A method is performed at a system that comprises one or more video cameras and a remote server system. The method includes obtaining, via a video camera of the one or more video cameras, a continuous stream of video data for a scene. The video data stream comprises color video data in accordance with a determination that the scene has illumination above an illumination threshold and comprises infrared (IR) video data in accordance with a determination that the scene does not have illumination above the illumination threshold. The method includes colorizing the IR video data based on a subset of the color video data. The method further includes presenting the colorized video data to a user in real time.

Abstract: Example systems described herein may include one or more sensor devices that may be powered by a power device. The power may be transmitted from the power device to the sensor devices through a waveguide (e.g. a body). In some examples, the power device may be implemented using a near-field communication device (e.g. a mobile phone configured for near-field communication (NFC)). Magnetic fields generated by near-field communication devices may be transduced into electric fields and applied to a waveguide (e.g. a body) for transmission to the sensor devices. The sensor devices may harvest power from the signals received from the waveguide (e.g. the body).
