alt Hacker NewsReally interesting, thank you! They do seem very rare in comparison to ANPR, although maybe I'm not looking for the right thing. Durham, Plymouth and Wokingham are talking about Red Speed and Acusensus but given basically all 300 odd councils have discussed ANPR at some point in the last year, that's a tiny percentage.
No, I think you are right- they are not common in any way yet and hopefully will stay that way. Although with the fly-tipping issues here, if it could be done in an anonymous way, I would actually welcome the camera's that detect people dropping rubbish!
