[VIDEO] Totally Amazing: Linear Revolving Doors for Added Security

The linear revolving door is a novel structure patented by Barbecan Security Systems. The doors automatically move along with the flow of pedestrian traffic into a building, creating a temporary room for each person as they go through the entrance hallway. While in this moving room the individual can be scanned for weapons or bombs and be prevented from entering the building (or even forcibly pushed out by the doors) if a dangerous situation is discovered. A pretty cool video animation of the linear revolving doors in action can be seen on the Barbecan Security Systems website.
