Recent research has begun to address how CCTV operators in the modern control room attempt to search for crime (e.g., Howard et al., 2011). However, an often-neglected element of the CCTV task is that the operators have at their disposal a multiplexed wall of scenes, and a single spot-monitor on which they can select any of these feeds for inspection. Here we examined how 2 trained CCTV operato...

Despite the police-operated closed-circuit television (CCTV) system in Nairobi City County being operational since mid-2015, insecurity remains a big problem. Hence, this study endeavored to establish challenges hindering its effective use. The used convergent parallel mixed-methods design, integrating data from surveys, focus groups, and key informant interviews. sample was obtained police off...

Monitoring closed-circuit television (CCTV) for security purposes is a task requiring sustained attention and the processing of many complex, constantly changing visual elements. Studies of performance in such tasks reveal a high level of workload and rapid loss of performance as workload is increased. Similarly, laboratory based experimental paradigms suggest that performance in CCTV monitorin...

Using a simple but robust real-time algorithm that allows tracking of multiple objects in complex environments, the authors propose an application in automatic surveillance by linking blobs’ information, in terms of trajectories and positions, with the events to be detected. Working in the background of the CCTV surveillance systems and based on whether a selected event has been detected or not...

Automatic recognition of time and date stamps in CCTV video enables the inclusion of time-based queries in video indexing applications. Such ability needs to deal with problems of low character resolution, non-uniform background, multiplexed video format, and random access to the video file. In this paper, we address these problems and propose a technique that solves the difficult task of chara...
