I doubt this was fully legal. It's been repeatedly upheld that a private home has a reasonable expectation of privacy (this is a legal, not lay distinction) - which is to say that recording inside a private home, even without trespass, can be illegal.
Something being in plain sight is not a sufficient condition for legally photographing it. You cannot, for example, point a camera into your neighbor's bedroom, photograph the results, and distribute it on the internet, even if, say, the camera was on public sidewalks.
