Does anyone know what's the exact effect of security cameras in the First World Bank mission? We played the mission with and without destroying the cameras, and we're not sure it's making a real difference. The Payday's wiki says this:
By the time you start heading to a room with a copier you probably have killed or tied up most of the bank security personnel and shoot some cameras to weaken future SWAT assaults on your team a bit.
But I doubt it. The only difference we noticed is that only two elevators' doors will open if you destroy the four cameras in the security hall. If you don't, the four gates will open.
