That's just turning the screen around and making the customer do the same thing as the employee based off the fact that CCTV systems will work with people's decency so as to not steal. It's not automation, the same actions still occur.
That only works because of the previous success in semi automating checkout, and scaling up the efficiency of security via CCTV.
Checkouts weren't previously automated, they were digitised. The reporting of data was no longer a manual process so you could argue the backoffice tasks were automated.
