> Maybe change that to "many people"; "anyone" isn't accurate. For example, at my workplace, there are security cameras at a couple of the doors, but none in the office itself. I don't think I'd stay long if there were a bunch of cameras here.
All the big tech cos I've seen have cameras everywhere. The cameras aren't typically for the employees, they are to keep visitors from walking off with valuables.
I've heard of my coworkers having entire computers swiped, and smaller items like phones were also at risk. An old office manager had someone go through a pallet of desktops and haul more than one of them off.
With many millions of dollars of hardware just sitting around, not to mention the IP contained on the machines, security cameras are a rather good idea.
These buildings are of course locked, but lots of vendors pass through, and determined people can tailgate past checkpoints.
