Earlier quoted context omitted.
"if I have video footage of someone approaching my door, not knocking and just looking aroud to then leave; and I'm given the option to track if that person shows up again in future video footage, you bet I would use that option." This sort of thing is one of the reasons why I fear these systems. A world where this is common is a world where it's no longer safe to take a stroll through your own neighborhood.
You've got all the rights in the world to walk by my house on the sidewalk and doing so an unlimited number of times will raise no suspicion from me. The minute you cross onto my property you're going to show up on multiple cameras that are pointed right at the boundary line. You rights to do whatever you want stop when you cross that line. I dont think you could convince me that this makes you any less safe.
I'm not trying to, because when it comes to my own security, what you think is or is not safe isn't relevant. Just as what I think isn't relevant to yours.
