Ergonomics is the study of the human workspace and equipment. A bad habit of mine is doing things without thinking it through. I also have bad posture. Our work stations are ergonomicly sound. They should sit up straight.
I think it's justified that they blur them out otherwise, they might be able to get an inside view and maybe rob the place. With them blurred they won't be able to do that. If they do un blur it they could search and find a way in. they might go in and search for carmeras and safe spots where cameras cant catch them. They could find the way to the item they want to take as well.
