Is OP saying that the proximity beeping would be done by the cameras (some sort of computational videography like an iPhone?) rather than the old sensor type or that the only answer would be visual? If the latter, that’s crazy - my truck has amazing cameras but if I am trying to back up with the sun low in the sky behind me, or the camera covered in dirt or snow, it is useless.
