If you're in CA, I learned recently that any use of automatic license plate recognition here is regulated and has a bunch of rules. Technically just turning on the ALPR feature in your consumer level camera is illegal if you don't also do things like post a public notice with your usage and privacy policy.
The law is a bit old and seems like it was written under the assumption that normal people wouldn't have access to ALPR tech for their homes. I suspect it gets very little enforcement.

Great. Let's stop using Ring cameras for security then
Cities in CA also often put their own ALPR restrictions on btw so you'll want to check both state and local laws.
Interesting. It actually is posted that my property is under video surveillance. Colorado though. It seems like you would have a poor argument that you can’t collect and analyze images of a public space.
One cynical aspect of Colorado law I learned about going down the ALPR rabbit hole: in Colorado it is a higher class misdemeanor than regular traffic violations to purposely obfuscate your plate to interfere with automated plate reading. The law is “well written” in that there is little wiggle room if they could somehow prove your intent. Meanwhile it is a lesser class violation to simply not have a plate at all. Their intent feels pretty clear to me.
