Closed-circuit television (CCTV) cameras were installed in five urban center entertainment districts that attract economic activity at night and relatively high pedestrian and vehicle traffic. The towns and cities were Ashford, Eastbourne,

By increasing actual detection through surveillance, early intervention may be possible to avert a crime or violence, and offenders may be removed. If surveillance leads to the early detection of precursors to violence, injuries may decrease.
Assault-Related Emergency Department Visits
Sivarajasingam and colleagues (2003) found that visits to emergency departments (EDs) for assault-related injuries decreased by 3 percent in the intervention sites and increased by 11 percent in the control sites. This difference was statistically significant. There was variation across the sites. For instance, in the control sites only
Police-recorded violence increased in both the intervention and control sites. Although it increased more in the intervention sites (11 percent) than in the control sites (5 percent), the difference was not statistically significant. There was variation across the sites. For instance, in only one of the five control centers (
