I wonder what would happen if you reached through a gap in the products (perhaps one is a big seller and the shelf location is empty) and pulled an item from the back of the next product's location. Like - reaching where the strawberry Pop-Tarts are normally stocked, to remove a box of the cinnamon flavored. (Why would you do this? Normally the older product is on the front of the shelf so it gets sold first) Your hand would be out of view of the ceiling-mounted cameras so it can't see directly (covered up by the shelf above). Your arm would be in the strawberry opening but you'd pull out a cinnamon. Is it's vision system good enough to tell the difference from the packaging, or does it just go off position when you pull it off the shelf?
