RT Article T1 The History, Policy Implications, and Knowledge Gaps of the CCTV Literature: Insights for the Development of Body-Worn Video Camera Research JF International criminal justice review VO 31 IS 3 SP 304 OP 324 A1 Piza, Eric L. LA English YR 2021 UL https://krimdok.uni-tuebingen.de/Record/176509822X AB Closed-circuit television (CCTV) and body-worn video cameras (BWVCs) have rapidly spread throughout policing. Such widespread deployment has heightened the importance of identifying best practices for both of these technologies. The research community has worked toward the identification of such best practices, with bodies of knowledge emerging for both CCTV and BWVCs over recent decades. Given its earlier emergence, research on CCTV is more developed. Nonetheless, the BWVC literature is quickly becoming robust, with BWVC research developing at a much more rapid pace than research on most other police technologies. This essay reviews the CCTV and BWVC literatures across four main areas of inquiry: (1) program effect and common outcome measures, (2) contextual factors influencing program effect, (3) intervention costs, and (4) implementation issues. Specific attention is paid to knowledge gaps within the CCTV literature and how BWVC research can avoid (or, in certain cases, already has avoided) similar knowledge gaps.
