ANPR system query

fivegoldstars

Quick query, more to satisfy my own curiosity than anything else.
If an unmanned, ANPR controlled car park is free for x mins, then chargable thereafter, but the P&D does not require registration entry, how are tickets issued for non-payment or exceeding paid period?

They supposedly have ANPR on the entry and exit points of the car parks but the systems being used by the PPC's appear to be cheap made in China ones as they don't appear to work properly.

Yes, so if they clock you in and out for say, an hour, how do they know what, if anything, you paid for that hour?

I presume the software reads the plate, notes the times and does a few simple sums. It could be linked into a P&D machine, where you have to enter the number plate, in part or full.

SCL1 in at 18:00. SCL1 out at 18:30. 18:30 minus 18:00 = 30 minutes. 1 hour paid for. 30 minutes is less than 1 hour. No ticket.

SCL1 in at 18:30. SCL1 out at 20:45. 20:45 minus 18:30 = 2 hours 15 minutes. 2 hours paid for. 2:15 is greater than 2 hours. Ticket. Ker-ching!

Or, SCL1 in. SCL1 out. Number plate not entered (due to a "loose" connection). No time paid for. Ticket. Ker-ching!

I get that part - like I say, in this scenario, it is a simple P&D machine - no registration entry.

You forgot the
SCL1 in at 10;30 SCL1 out at 11.00: SCL1 back again at 18:30 and SCL out at 18:50 result ticket for overstay from 10:30 to 18:50
Ker-ching.

I keep trying the "double drive through", every time I visit or drive past my local APNR monitored car parks, to no avail.

Re the OP's question, if the P & D machine does not require your registration then I don't see how the ANPR can enforce anything. It may be a bluff to try to encourage people to pay. Why don't you see if you can get a ticket to find out?

The ticket in question reads time in car park x mins, time paid for 0 mins.
The only thing I can think is that it was the only car in the car park, and no tickets were issued by any of the machines after it arrived. Just seems a little strange.

Probably the usual fake, if you are certain the ticket machines do not identify the vehicle the ticket is bought for. Or was it issued by a person? Which is a somewhat loose description of one of their drones...

I am not at all suggesting anyone else should do this and I am very careful not to do this on a public road, but a couple of pieces of black tape which magically changes an F to an E or a J to a U can confuse the b***ard cameras (Also not fitting anyone else up as the number I may or may not be impersonating does not exist)
