You can certainly get cameras like that, they're not the norm. You can object to any privacy feature by pointing out that it doesn't provide guaranteed security

You can certainly get cameras like that, they're not the norm. You can object to any privacy feature by pointing out that it doesn't provide guaranteed security. Personally I am tired of having my privacy eroded by people holding themselves out as security realists who are always coming up with new ways to break things and/or normalizing existing ones.
