We are getting off track here, I'm not talking about the use of CCTV per se just the expression that most people use, when confronted with "Tracking"
Via CC / debit cards, their mobile phone and possibly Alexa / echo and "smart" TV's.
Data harvested by cc/Debit cards is very different from data obtained by mobile phones and the possibility of Alexa type devices. For the record the GPS on my phone is turned off, and I won't have an alexa type of device in the house.
Photography has been around in all genre a lot longer than CCTV.
There are probably "Grandfather rights" protecting that.
Of course, I don't know for sure, and its a whole new discussion.
FMU, CCTV has used "photographer rights" as the means to allow CCTV.
