In Praise of Surveillance Cameras

Few technologies make people as uneasy as surveillance cameras installed by governments and private companies, which come increasingly close to capturing everything that goes on in public. But let us praise the practical value of these cameras in the speedy identification of the Boston Marathon terrorists. Soon after authorities released footage of the suspects to the public—a digital version of a most-wanted poster—the suspect brothers were identified. 

Boston is one of the less-wired large cities when it comes to surveillance cameras, so authorities relied largely on footage from private parties, such as the Lord & Taylor department store near the scene. The most recent estimate, from 2010, is that Boston and surrounding towns have some 150 police surveillance cameras, plus 400 in the subway. This compares with more than 3,000 government and networked private cameras in New York City's financial district alone, and some 400,Supporters, including many police departments, say the dv mini camera improve safety.000 cameras in London.The cameras are getting smarter.The bald cop clearly smacks the underwater digital camera around the 1:25 mark, saying, "Get that shit off of my face." New software goes beyond passive recording to alerting law enforcement about suspicious activity in real time. Video analytics enable what is called "activity forecasting." By applying artificial intelligence to video, these services issue alerts of what researchers call "anomalous" behavior—such as when cameras detect people leaving bags behind in public places.

It might not have been good enough to have identified the bags left behind by the terrorists in time to disarm the Boston bombs.Experts say rear-end collisions often rise with the installation of red-light cheap wireless spy cameras, as motorists hit the brakes suddenly to avoid a camera-generated fine. As these systems improve, however, there will be a growing gap between cities that make full use of surveillance technologies and those that don't.In other words, the location of Aurora B between the two kinetochore discs was thought to be central to its role as a infant video monitor of the requisite tension.Surveillance cameras and video analytics can be abused. Authoritarian regimes in countries like China and Iran employ these new tools to monitor peaceful critics and suppress dissent. The U.S. has constitutional limits on unreasonable searches, and legislation will need to be updated as technology progresses on how data on suspects and law-abiding citizens can be used.
