It's not clear that "on your property" counts as "in public" in all cases.
The line between "please don't point your camera onto my property" - something I would respect as a courtesy regardless of the law - and "I'm going to cross the street not to interact with this person" goes straight through mental illness in my opinion. Normal, stable people do not behave that way.
Because of this, it's legal for someone to point a camera right inside your window or front door. It's also illegal (public indecency) for you to be naked in your own window or open door.
That's legal in Canada, or at least the police won't arrest you if you do it in your apartment across from a school.
1) acceptable behavior
2) enforceable, practically
I think video recording laws are largely influenced by 2).
I can angle my Ring camera to my smoking hot neighbor so I can record her doing yardwork. Creepy AF (breaks rule 1) but at what angle is it not obviously deliberate? Turned 10 degrees toward her lawn? 30?
Point being, I think US recording laws are too liberal but we need a defineable limit for privacy.
Maybe photon distance? Capturing photons traveling further than 30m into the aperture is invasive? (half kidding)
The nextdoor homeowner probably has a right to setup a tripod, a laser pointer (or a similar bright spot light) and point it directly at the neighbor's Ring camera iris.
Probably too late to add that this was a hypothetical, but I'm glad the voting on this indicates how much we despise what's legally allowed.
