@TrinityTaylor This is interesting. When I was doing all the testing for my Crime guide (here) I received Bank robbery only on the high-tier level and got around 50k net when taking out everything. So this might have also changed or bugged after March patch like the door(?).
At Nooks you can actually walk around most of the cameras. I checked again and yes there is one which you need to take out if you want the money from the 2 POS Machines. These bring you between 4-5k in addition. Without these you can get both jewelery boxes and the safe without any risk for around 13 -15k (the money / item amount varies a bit per heist).
See here, the path in green is the one you can take to be safe without triggering alarm. The 2 POS Machines circled in red trigger alarm if you don’t disable the camera. But the jewelery box next to them is safe:
Also on the upper floor you can safely take out both the safe in the extra room and the jewelery box on the table without triggering the alarm.
As long as your Handiwork, Programming and Crime skills are not very high it is probably much more safe to take the 13-15k without any risk and leave the 2 POS Machines alone.
