The point I was making was for people who thought this was cellphone cameras and that it would somehow work even if the camera wasn't actively running.
As far as war driving with an sdr you'd probably occasionally find something interesting, but the vast majority would be cameras just pointed back out at the street. I think you'd mostly see stuff where if you wanted to spy it would make more sense to hide your own camera because it's already public.
All that said, I would lose my shit if Hollywood did something believable for once and used this for a heist movie.
