Who uses dummy cameras? Evidently, the fifth busiest train system in the US, with 125+ million annual rides.
A fascinating story from a San Francisco paper, key quotes:
"BART Director Tom Radulovich of San Francisco, who has been on the board since 1996, said that when the cameras were installed on trains, directors knew some were not real. He said he couldn’t recall the agency’s rationale, but he assumed it was budgetary.
“The thought was that they had a deterrent effect because some people thought they were real,” he said"
"Chronicle reporters walked the length of seven BART trains on Wednesday, taking note of the surveillance equipment. In all, 173 of 228 cameras on the cars — or 76 percent — appeared to be dummies."
