My understanding of what happened is that the till was counted as off, and then it was confirmed that it was them through the cameras.
There are anywhere from 2 - ~6 people who can open the till in the store at any time at that location, thus the need for the cameras.
Edit: Obviously not the best OpSec, but that was the workflow at that point, and hiring enough staff to make that not the case was non-feasible.
