According to SecurityInfoWatch, global spending on video surveillance is predicted to grow to $2 billion in the transportation industry and $4 billion in the retail industry by 2013. The prediction comes from a report by ABI Research, New York.

Reasons for the expansion include firms within these industries using closed-circuit television cameras for applications other than surveillance, such as for liability prevention, analysis of client behavior and store design.

According to ABI Research vice president Stan Schatt, a number of transportation facilities, including rail stations and airports, have started using cameras to record accidents to prevent phony lawsuits, and retail stores are using them to help determine how they can better manage their facilities and target consumers.
