‘Mass Transit Cameras Spot Bad Guys, No Human Judgment Required’
June 7th, 2012And while we’re at it, how about using Google searches to identify pre-crime?
Via: Fast Company:
A new breed of security cameras can supposedly detect terrorism and crime without a human judgment call–and mass transit agencies are shelling out big bucks for the product. San Francisco’s Municipal Transit Authority, which oversees the city’s MUNI trains, has signed a contract with security firm BRS Labs to deploy cameras to 12 subway stations that use algorithms and machine learning techniques to spot anomalous behavior.
BRS Labs is a security firm that provides behavior recognition software for video surveillance. The company’s clients include government, tourist attractions, military bases, and private industry; BRS’s software issues real-time text alerts when cameras detect strange behavior. Servers connected to security cameras observe locations for weeks at a time and then establish a baseline of “normal” behavior based on this timespan; anomalous activities afterwards (loitering, abandoned packages, abnormally high/low numbers of passengers) trigger an alert. No tripwires or programming of initial parameters are required.
According to a publicly available product bid, the San Francisco MUNI project will include up to 22 connected cameras at each train station; video monitoring will be conducted by train control, MUNI Metro East facility, and in-station personnel. The video systems will build memories of observed behavior patterns that mature with time; the systems, in the bid’s words, “[have] the capability to learn from what [they] observe.”
