When does CCTV help investigations, and why does it sometimes not?

Research Institution / Organisation

Nottingham Trent University

Principal Researcher

Matt Ashby

Level of Research

Professional / Work-based

Project Start Date

March 2016

Research Context

​CCTV has been widely used for crime prevention but there is little evidence on its value for criminal investigation.

This project aims to identify how often CCTV is useful in investigations of different types, and in what circumstances.

Research Methodology

​The researcher will be given access to records of 250,000 investigations conducted by British Transport Police over five years.


Statistical analysis will be carried out to identify how often CCTV is (a) available to and (b) useful for investigations. Logistic regression models will be used to identify the circumstances in which CCTV is and is not most likely to be useful.

Interim reports and publications

First stage of the research has been published:

Matthew P. J. Ashby; "The Value of CCTV Surveillance Cameras as an Investigative Tool: An Empirical Analysis"; European Journal on Criminal Policy and Research; , Volume 23, Issue 3, pp 441–459

Date due for completion
