There is a also a large research literature examining the extent to which the introduction of CCTV causes spatial displacement of crime. A systematic review of this litterature published in 2009 concluded that CCTV schemes "usually showed evidence of no displacement rather than displacement or diffusion of benefits". Similarly, a more recent review of randomized controlled trials and natural experiments assessing the effects of CCTV concluded that the "evidence on the prevalence of displacement and diffusion of benefit was mixed".
