How important is cctv in crime reduction

The evidence suggests that the use of CCTV systems without a dedicated police operational response may be effective at reducing vehicle crime and less effective at combating violence, although the way the system is implemented and used appears to be important in achieving any crime reduction. CCTV may also be more effective when bundled with SentrySIS is a secure cloud based software system that helps organisations in the UK reduce and manage crime in a much more efficiency way. This is achieved by providing police constabularies, national retailers and business crime reduction partnerships with the necessary software applications that save time and people resource Apr 21,  · The most important is that if CCTV is made available to investigators then it is likely to be useful in a substantial proportion of cases. At least in the case of railway crime, CCTV appears to be a powerful investigative tool, particularly for more-serious crimes.

Evidence-based policing - Wikipedia

CCTV cameras can be used to aid crime prevention, the detection of offenders, and crowd control or public order scenarios. The focus of the reviews are the prevention of personal and property crime. This summary draws primarily how important is cctv in crime reduction one meta-analytic review Review 1. The majority of studies in Review 1 were carried out in the United Kingdom 34 studies and the United States 24 studies.

The remaining studies were conducted in a range of other countries including: Canada, South Korea, Sweden, Norway, Spain, Poland and Australia. Review 2 included a meta-analysis of 13 studies that were carried out in England and which used multiple outcome measures victim-survey records and police records. The second review included case studies conducted in car parks, deprived housing estates and control rooms, and discussed interventions used alongside CCTV, such as: street lighting, community wardens and police operations.

Review 3 is an earlier version of Review 1, covering 41 studies, and contributes to the Implementation and Economic sections of this summary.

Information has only been included from Review 3 where it provides information which has not been offered within Review 1 or is used comparatively. You may also be interested in the toolkit entry on body worn cameras. Overall, the evidence suggests that CCTV has reduced crime, but there is some evidence that it has increased crime. The meta-analysis in Review 1 found that CCTV was associated with how important is cctv in crime reduction statistically significant decrease in crime.

Three of the 76 studies reported a statistically significant increase in crime. The studies in Review 1 looked at effectiveness of CCTV on different crime types.

No overall statistically significant effect was observed for violent crime 29 studies or disorder six studies. Review 1 reported that CCTV did not, overall, lead to crime displacement: only six of the 50 studies that included adjacent treatment and control areas reported evidence of displacement. Review 1 demonstrated a high-quality design in terms of having a transparent and well-designed search strategy.

It considered the possibility of publication bias, as well as ensuring that only studies of comparable quality were pooled to create an overall effect size. The authors also conducted analyses of possible displacement and diffusion of benefits following the intervention.

The largest and most consistent effects how important is cctv in crime reduction CCTV were observed in car parks and, to a lesser extent, residential areas. Five of the eight studies on CCTV in car parks demonstrated statistically significant reductions in crime. Five of the sixteen studies on CCTV in residential areas reported statistically significant reductions in crime.

Review 1 reported more mixed outcomes when CCTV was used in other places. A meta-analysis of 33 studies found that CCTV in town or city centres did not have a statistically significant effect on crime overall seven studies reported decreases in crime and three reported increases in crime in town or city centres with CCTV compared to those without. Two of ten studies on CCTV in housing complexes reported statistically significant reductions in crime.

Although none of the four studies on CCTV on public transport systems reported statistically significant effects on crime, how important is cctv in crime reduction, the review how important is cctv in crime reduction commented that this may be due to the small sample size rather than the ineffectiveness of CCTV. Review 1 found CCTV to be more effective when implemented in UK settings than in locations in other jurisdictions largely the USA and South Korea.

Review 2 suggested that CCTV can also be effective in the outskirts suburbs of a city, however it was not possible to distinguish whether reductions in crime were attributable solely to CCTV as they coincided with improvements in lighting. Review 1 found that CCTV was more effective when it involved active monitoring - where incidents could be monitored and proactively addressed in real time.

CCTV implemented on its own or alongside one other intervention did not have a statistically significant effect in reducing crime. Reviews 1 and 2 both linked the effectiveness of CCTV schemes to the level of coverage provided by the camera. Review 2 reported a statistically significant correlation between crime reduction and schemes with a higher degree of camera coverage. Reviews 2 and 3 also observed that the types of camera tested in studies varied e.

pan, tilt, and zoom cameras and noted that their technical specification e, how important is cctv in crime reduction. ability to record in reduced light should be considered during implementation. Success was linked to public and political support, which was thought to vary by context e. Implementation of CCTV was thought to benefit from being problem-oriented i. Review 1 did not discuss the costs of CCTV in detail.

Review 3, noted that re-deployable or mobile cameras—those that can be moved easily between locations—might be less costly than fixed cameras. The reviews did not discuss the monetary value of the benefits from CCTV, or provide a formal economic analysis. The reviews noted that the primary studies varied in important ways including the duration of the follow-up periods e.

those in the UK tended to have longer follow-up. The effectiveness of CCTV on outcomes other than crime reduction, such as detection of crime, resource deployment, or on public order, are not considered.

The authors highlight some gaps in the research base—e. There is also strong evidence that it is particularly useful in reducing crime in car parks and, to a lesser extent, residential areas.

The most significant reductions were for drug crimes, vehicle crime, and property crime. There was no evidence of an effect on violent crime and disorder. CCTV was found to be more effective when it involved the active monitoring of live footage, had higher levels of camera coverage, and used in combination with multiple complementary interventions, such as street lighting.
