Security cameras don't typically record sound, which I'm guessing makes them not illegal under such statutes. Or they're plainly obvious, at least it's plainly obvious that they're recording video, or at least in commercial spaces there are signs up mandated by law, or something. Anyway, you can't surreptitiously record a conversation you have with somebody on your own property in many states.
