Absolutely agree... but the CA law is clear that tracking license plates get special treatment! It being public space doesn't matter. It's wild to me that how you analyze the video is regulated. Also that no similar regulation for the regular public doing facial recognition exists. Just ALPR.
I wonder how I'm supposed to comply with the law if I were to take a public webcam feed, like one from a highway[0], and run ALPR on it myself. I obviously can't post any notices there. And I'm not the camera operator so can't comply with anything related to that. But I would be doing ALPR which does require I follow rules. ¯\_(ツ)_/¯
Will be interesting to see what happens to the law. It feels outdated, but I'm doubtful any CA politician is going to expend karma making ALPR more permissive. So I bet it'll stay on the books and just go largely unenforced.
They still might be able to regulate it for all practical purposes.
