I guess I should explain a little more, although I just realized that changing batteries would be a problem. I am looking for a camera that can be mounted high up on a pole to get a view of a race track. Probably an outdoor camera that can be left there in the weather throughout the season.
I like your idea and might try it, but the main goal is to get the video without having to retrieve the camera every time.
