Security Cameras in the New York City Subways
The New York Times has an article about cameras in the subways. The article is all about how horrible it is that the cameras don’t work:
Moreover, nearly half of the subway system’s 4,313 security cameras that have been installed—in stations and tunnels throughout the system—do not work, because of either shoddy software or construction problems, say officials with the Metropolitan Transportation Authority, which operates the city’s bus, subway and train system.
I certainly agree that taxpayers should be upset when something they’ve purchased doesn’t function as expected. But way down at the bottom of the article, we find:
Even without the cameras, officials said crime in the transit system had dropped to a record low. In 1990, the system averaged 47.8 crimes a day, compared with 5.3 so far this year. “The subway system is safer than it’s ever been,” said Kevin Ortiz, an authority spokesman.
No data on how many crimes were solved by cameras, but we know from other studies that their effect on crime is minimal.

From the original article: “Part of the problem is that the authority is trying to retrofit a century-old transit system with the latest technology. Recorders are often housed in communications rooms, which have to be carved out of creaky, cramped subway stations. The requisite wiring and electrical equipment, built for the air-conditioned sterile space of a server room, do not always withstand conditions underground.”
Unless they’re trying to do something far more complicated than simply recording, playing back, and forwarding video, this is not rocket science.
You could take a SheevaPlug embedded computer running Linux and a 1 TB hard drive, stick them in a waterproof case with power and video feed coming in and Ethernet or encrypted WiFi coming out, and that would be a box the size of large paperback book that would last for years in a subway tunnel. And if, for some bizarre reason, it didn’t, it would be cheap enough to replace frequently.
But then, that assumes people actually want to accomplish the goal and know what they’re doing.
