According to the Xinhua News Agency, Austrian researchers at the Vienna University of Technology have created a computer-based CCTV surveillance system that identifies and monitors suspicious behavior by people inside banks. The system automatically alerts banks when the suspicious behavior has been identified. The CCTV system uses a mathematical algorithm to identify atypical behavior inside the bank; the researchers have determined that 95 percent of bank customers tend to stay in the same part of the bank when waiting to conduct a transaction. One hitch in the system that researchers are still trying to resolve is reducing the number of false alarms generated by children. There were 56 bank robberies in Vienna in 2006, up from 39 in 2005.
