Man or a Gorilla? Performance Issues with CCTV Technology in Security Control Rooms
نویسندگان
چکیده
Despite increased usage of CCTV, and technological advances of surveillance systems, there is still relatively little understanding of how well it actually works for the many purposes for which it is deployed. Most purposes require that humans detect and respond to events in an appropriate and timely fashion. From a human factors and Human Computer Interaction (HCI) perspective, it is important to identify whether CCTV systems support human operators effectively, and are fit for the purpose. To answer this question, we take a SocioTechnical System (STS) perspective of CCTV: any system is deployed for one or more purposes, and has a number of stakeholders, who carry out a number of activities. In this paper, we focus on one set of stakeholders CCTV operators, and examine the activities they carry out in control room environments. We use observations and interviews to identify issues they encounter in the operation of the system. Our results show that task performance is currently impaired because of high screen to operator ratio, absence of camera maps, or lack of integration with other databases. Findings in this paper present the challenges CCTV operators are faced within complex city centre control room environments.
