If they wanted you to know, they'd have told you. Since they didn't tell you, they don't want you to know. If you bring it up, they'll just hide the camera better. I never do anything that I wouldn't do in front of the bosses (except in the bathroom where I have the expectation of privacy) so I don't care if they have a camera. I would not, and have not, said anything in your position.
I think you should get over yourself. In one paragraph you say you're fine with it, but in the very next make it clear you're not. What's the point of having a camera if you're going to tell someone about it.
