Abstract
A system for video recording for a vehicle includes a camera system, a first wireless module, a second wireless module, and a controller in electrical communication with the camera system, the first wireless module, and the second wireless module. The controller is programmed to transmit a plurality of original training signals on a plurality of subcarriers using the first wireless module. The controller is further programmed to receive a plurality of propagated training signals using the second wireless module. The controller is further programmed to determine a deviation between the plurality of original training signals and the plurality of propagated training signals. The controller is further programmed to determine an occupancy status of an environment surrounding the vehicle based at least in part on the deviation and record a video using the camera system in response to determining that the occupancy status is an occupied status.
