Posting a guard on duty accomplishes nothing. Putting a guard in an isolated dedicated security room, with live cameras, means the silent alarm is always triggered.

I won’t speak about banks, but many (most?) security guards at businesses aren’t even armed. They are there as a deterrent, but also to witness and document. They are also (usually mildly) trained to defuse a violent situation and get any robbers out the door without bloodshed.
