This is a different point. Surveillance pricing isn't used in parking, which is the point made by GP.
On the parking enforcement side of things: maybe you could argue that it's surveillance? It depends on what you mean by surveillance, a term that I think is easily overloaded so as to conflate different things. Depending on the definition, that's also how retailers detect and mitigate shoplifting, and it's also how the barista knows that I'm ready to place an order, and myriad other things that could potentially qualify as "surveillance".
