Grandcentral (which was bought by google and is now google voice) had a great feature that when you received a phone call you could record it at any time. That feature was dropped by google. The laws vary by state. The state I used to be in you needed two party consent. The state I am in now only one party has to consent (so you can record your own phone calls in a one party state).

I believe that the same applies to surveillance cameras which is why most of them don't have audio they only have video.

Oh ok, here:

"Recording audio without the persons permission is almost always illegal, that's why our covert cameras don't have microphones. "
