This is incorrect, it is not a felony to record audio from a security camera in the US. Two party /all party consent only applies to confidential communications.
“...it is possible to violate the Wiretapping Act (and thereby commit a felony) by pointing a camera at a person speaking on a cell phone and creating an audio recording of part of the telephone conversation.”
Recording audio is always fraught with risk. You should avoid it, especially in indoor locations that you do not control.
One party/all party consent laws only apply to confidential communications, or put another way private conversations, not anytime a phone is used. If you can only hear one person speaking, it is not a conversation. And even if you can hear both people, like if they were on speakerphone, someone talking on speakerphone in a public place is not having a "private" conversation.
That depends on the state. In Florida, I had to put up notices that audio was being recorded in one room in order to hook up a microphone to a surveillance camera.
If you're not a party to a conversation, then one-party rules don't apply. I.e., in one-party States you can record any conversation to which you are a party, but you can't eavesdrop on conversations that you're NOT a party to.
This means you can't leave a microphone at a bus stop to record random conversations, say, not without a) owning the bus stop, and b) loudly announcing the presence of the microphone to all users of said bus stop. Replace "bus stop" with any public space. This also applies to private spaces as well, even when you're the owner. Thus you can have video surveillance at any office, but audio surveillance is generally a big no-no.
GP refers to zero-party recording. I would be surprised if surreptitious (i.e., not announced) audio recording by non-parties were legal anywhere at all in the U.S.
If you're standing in front of a window and can see out (and can be seen), you don't really have a reasonable expectation of privacy. This applies to my single floor single family residence. If I want privacy, I close the blinds and/or drapes.
As a matter of courtesy, I never aim a telephoto at windows. Paparazzi are an entirely different class though in that most have no "class" anymore it seems.
You don't have a practical expectation. Its reasonable to expect polite neighbors not to stare in windows, take photos etc. Used to be called a 'Peeping Tom' and was actionable. Nowadays we've become jaded?
This is a poor example for two reasons. The reasonable expectation of privacy standard is for audio, not images. And you do have an expectation of privacy in your own hotel room
Not a Lawyer, but it looks like it varies by state. CA penal code 647 j makes this illegal even without entering the property, but mississippi code 97-29-61 does require entering the property.
