Study Shows Video Surveillance Reduces Crime

By IPVM, Published May 06, 2021, 10:42am EDT (Info+)

A new 2021 academic study on the global expansion of CCTV has found a 10% decrease in crime in areas using video surveillance vs those that do not.

But how trustworthy is that number?

Inside this note, IPVM examines the study published jointly by US/UK-based authors, discussing its finding that video surveillance reduces crime and pointing out limitations due in part to the age and geographic scope of the study data.
