“Between 2007 and 2010, researchers from the Urban Institute’s Justice Policy Center studied public surveillance systems in Baltimore, Chicago, and Washington, D.C., to measure the extent of their use, their effects on crime, their other benefits, and their costs. While results varied by area, surveillance systems in Baltimore and Chicago produced more than enough benefits to justify their costs. No cost-benefit analysis was conducted in Washington, D.C., because the cameras didn’t show a statistically significant impact on crime there.”

Unlike other recent studies on cameras, the Urban Institute researched monitored surveillance systems, a key factor in overall effectiveness.
