Public Buses Across Country Quietly Adding Microphones to Record Passenger Conversations

Public buses in cities across the United States are being equipped with microphone-enabled surveillance systems funded by the Department of Homeland Security. These systems can record and store conversations, raising concerns about privacy infringement and potential misuse by law enforcement agencies. The audio recordings can be accessed remotely via a built-in web server, and are often paired with camera images to create synchronous recordings. Some cities that have installed or plan to install these systems include San Francisco, Eugene, Traverse City, Columbus, Baltimore, Hartford, and Athens. Transit authorities argue that the systems will improve safety for passengers and drivers, as well as resolve complaints from riders. However, privacy experts express concerns about the potential misuse of the audio recordings, including identification of individuals through facial or audio recognition technology.
