What international research shows

Published findings on this kind of intervention elsewhere, not results measured on this site.

• The ACFE's 2026 study of 2,402 occupational fraud cases in 143 countries found the median scheme ran 12 months before detection. Frauds caught within six months had a median loss of US$40,000, against more than US$1.1 million for schemes that ran over five years, and controls such as management review and proactive data monitoring were associated with lower losses and faster detection.

• A 40-year meta-analysis of 76 CCTV evaluations found about 14% lower odds of crime in areas with CCTV than in comparable areas without it. The effect was modest overall, and the review found no significant effect on violent crime, which is why cameras work best as one layer alongside access control and response.
