The multimillion dollar upgrade is underway in several US cities, including San Francisco, Eugene, Traverse City, Columbus, Baltimore, Hartford and Athens, reports The Daily, which obtained documents detailing the purchases.
The money partially comes from the federal government. San Francisco, for example, has approved a $5.9 million contract to install the eavesdropping systems on 357 modern buses and historic trolley cars over the next four years, with the Department Homeland Security footing the entire bill. The interception of audio communication will apparently be conducted without search warrants or court supervision, the report says.
The systems would be able to record audio and video from several locations in a bus for simultaneous playback. In Eugene transit officials explicitly demanded microphones capable of distilling clear conversation from the background noise. The recordings would generally be retained for 30 days. One of the systems produced for transport monitoring supports up to 12 high definition cameras, each with a dedicated microphone.
The system may potentially have additional capabilities added like timing the recording with GPS data from an onboard navigator, using facial recognition technology to identify people recorded or connecting wirelessly to a central post for real-time monitoring.
“This technology is sadly indicative of a trend in increased surveillance by commercial and law enforcement entities, under the guise of improved safety,” Ashkan Soltani, an independent security consultant whom the online newspaper asked to review specifications of equipment marketed for transit agencies, told The Daily.
