Would you also be fine with people filming you through your windows? Why not, after all it's visible from a public space with the right angle. And windows are just part of another kind of "fence".
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.
I use drapes and shapes to get privacy for my windows. My intent Here is to prevent school shootings and help investigate crimes that occur on my property or my neighbor's property. Definitely not my intent to stare at my neighbors in their private lives and they understand that completely.
How are cameras supposed to prevent school shootings? The best they can do is let you watch cops do nothing as we could see in Texas. Prevention is much more important and much cheaper but that's not done either.
And I don't know why I'd spend money in anticipation of a potential crime in front of my home, donating data to Amazon in the meantime. The police is already tracking phones and using other methods no single camera can match.
