"If a few of the "hundreds or thousands of *different* people" may remember seeing you, some of them may see you someplace else and be able to correlate and track you movements that way too; is that also an invasion of your privacy?"
Sure it is. *BUT* to go through and interview every single one of those people to recreate your steps is very, very labour and resource intensive. For someone to do that, they would have to have very, very good reason.
With a properly set up camera network and some software, tracking could be completely automated, allowing someone to track you and thousands others with no effort at all.
"The camera isn't trained only on one person and ignoring everyone else"
Got any proof for that? You have not idea how the cameras are set up. They're 'black boxes'. If someone wanted to, panning-and-zooming on a specific person wouldn't be hard if the cameras were equipped to do so. Even if not, as I said above, software could be written to track individuals automatically from the collection of video feeds.
"I don't understand why you you dislike being seen in public by a person with a camera"
Uhh... OK... I'm not sure where THAT came into the conversation. We're talking about permanent, mounted cameras (eg. on top of telephone poles or traffic lights), not Mr. Q-Random-Pedestrian with a Nikon. |
