Your trash analogy doesn’t hold up because trash becomes “public” once it’s on the street which isn’t part of your property. “Publicly visible spot on my property” is a meaningless phrase; it’s still my property, and I’m legally (here at least) allowed to raise an objection to the recording of it. I can’t and wouldn’t object to someone recoding the sidewalk in front of my house. I can, and absolutely will, object to…
I can't ask the people who drop their kids at the school across the street not to look at my yard, so why would I complain about a camera? Because it's always on and recording? Still not convincing to me. My exterior yard (the part not surrounded by a tall fence) is for everybody to look at. In fact lots of people stop by my house to look at our amazing maple tree and start conversations with us.
In the end it's private property and that makes it private by default. Nobody can forbid you from looking at it, but imho filming is just as invasive as parking the car there while having greater potential for abuse. Filming has intent that goes farther than just randomly looking around.
