    It’s possible to still track speed using a video feed instead. You just have to know the distance between two static points within the videos frame. Time naught = passes first static point, time final = passes second static point.

    Velocity = distance / time

    Although I’m not sure how or if this would impact the battery life of the device.

      Yeah, but I’m not allowed to just video tape the street all day long. A Doppler radar that gives me data to argue for a permanently installed speed control on the other hand would be fine
