I'm sure they're not extractable at scale, otherwise we'd have heard about it, but they're almost certainly extractable on a one-off basis if you have a big enough budget (one that likely outweighs whatever you'd stand to gain from it). It's just not the low hanging fruit of the system as a whole. I also expect it not to be the low-hanging fruit of these cameras, but it is still one possible attack vector.
