Re: A pretty simple concept really:
One client I worked at had a warehouse sized building kitted out as a call centre, which had several sets of airlock/tube doors down the sides to track people in and out.
Chatting to the security manager in advance of an upgrade to the swipe card system, he told me they'd had an incident where the server had failed, the doors had failed safe, i.e. opened, in the middle of the night and a fox had wandered in setting the burglar alarm off!
