This study measures the effect of CCTV in Newark, NJ across three separate crime categories: auto theft, theft from auto, and violent crime. CCTV viewsheds, denoting camera line-of-sight, were units of analysis. Viewsheds for treatment units were created by digitizing live CCTV footage within a geographic information system (GIS). Control viewsheds were created with GIS tools and aerial imagery...

The use of CCTV-surveillance by Flemish municipalities is increasing. A newspaper analysis, complemented with other information gives a first indication about the developments in this field and shows an evolution in the implementation of CCTV in Flemish municipalities. In the beginning CCTV was used to protect spots where public services are delivered. In a next phase, a reduced number of Flemi...

Airports are places that are heavily surveilled by different (technical) means, including CCTV (Closed Circuit Television). So far, the literature on CCTV has not paid much attention to the practices behind the screens of the CCTV monitors at airports. In this article, we present an in-depth, ethnographic study of the use of CCTV in the Military Police’s control room at Amsterdam Airport Schiph...

This paper reviews studies that have evaluated the effectiveness of closed circuit television (CCTV) in reducing crime, disorder and fear of crime in a variety of sites. The guiding framework for the review is Tilley's (1993a) model for realist evaluation, which focuses on the mechanisms and contexts in which CCTV might operate. The paper concludes that CCTV can be effective in deterring proper...

Six male and seven female English-speaking university students, with corrected vision of 20/20 (6/6), were trained using the closed circuit television system (CCTV) as a reading aid. This was an attempt to identify the essential factors in CCTV-aided reading. Active and passive observers were trained in pairs, with the passive observer being the yoked control of the active observer. The control...

We propose a novel approach to evaluating how effectively a closed circuit television (CCTV) system can monitor a targeted area. With 3D models of the target area and the camera parameters of the CCTV system, the approach produces surveillance coverage index, which is newly defined in this study as a quantitative measure for surveillance performance. This index indicates the proportion of the s...

INTRODUCTION Data mining is widely used in various areas such as finance, marketing, communication, web service, surveillance and security. The continuing growth in computing hardware and consumer demand has led to a rapid increase of multimedia data searching. With the rapid development of computer vision and communication techniques, real-time multimedia data mining is becoming increasingly p...

The number of closed-circuit television (CCTV) cameras in British town centres has rapidly increased in recent years. These increases are mirrored in Europe and North America. In Britain many of these cameras videotape town centres, 24 hours a day, 365 days a year. How do CCTV systems account for the space of the town centres in which they operate? What theoretical sensibilities can we use to e...

This paper examines the processes that bring about the creation of new public-space CCTV schemes. Through an appraisal of the grounded activities of the practitioners who make decisions over CCTV, the role of agency is identified as a particularly strong, yet relatively neglected, influence on its implementation. Moreover, beyond dichotomised notions of central structures and local agency, an u...

This article explores the introduction and diffusion of Closed Circuit Television (CCTV) surveillance systems in public places across the UK. In particular, it seeks to examine the diffusion of CCTV alongside the emergence of regulation and governance structures associated with its provision. By doing so, it is argued here, that the processes of diffusion, regulation and governance are inherent...
