There's an app called Wherearetheeyes that lets users report camera locations. I don't think it's going to do much good except maybe raising awareness. To help people avoid surveillance, you'd need a map of cameras including field of view and expected effective recognition distance. Even then, I'm guessing most public spaces would simply turn out to be no-go zones for anyone not wishing to have their picture taken.
