Some of the latest surveillance and security technology for banks and other financial institutions is almost mind-boggling. Motion sensors, infrared cameras, laser detection grids, and we haven't even mentioned the old standby of the closed circuit camera! Then you get to the insulated steel vaults, in which are dozens, perhaps hundreds, of secure safe deposit boxes, each of which requires keys, codes, or even biometric data to open! The layers upon layers of security at banks is astonishing, all put in place to protect our hard-earned money.
