By not caring about who can look at my front lawn, I am implying if that camera footage gets hacked I do not care. I own my lawn and can do whatever I want with the footage.
As for people walking or driving by, they are in public and have zero expectation of privacy. I live in a school zone with a high school of 3500 kids across the street, most walk home. No one would never believe in a million years the crap they do to my lawn and the neighbors. They throw trash in my lawn, leave soda cans and bottles at the end of my driveway so I literally have to either stop in the street and move them or run them over getting into the driveway. They throw things in the back of a pickup truck in my driveway. They do this to all 12 houses on my street. It is nice to have footage in case ANY of this results in criminal damages. And it is legal.
So if that is selfish, then I am cool with that.
