The use and implementation of public open street Closed Circuit Television (CCTV) surveillance systems in Central Business Districts (CBDs) in South Africa solely for the purpose of crime control (reducing street crime) or crime prevention (deterrence) has in South Africa been a relatively new intervention within the broader context of crime prevention programmes. One of the drawbacks to its im...

Closed Circuit Television (CCTV) operators are responsible for maintaining security in various applied settings. However, research has largely ignored human factors that may contribute to CCTV operator error. One important source of error is inattentional blindness--the failure to detect unexpected but clearly visible stimuli when attending to a scene. We compared inattentional blindness rates ...

Due to the population increase all over the world current road infrastructures are unable to keep up with the escalating transportation demands. This situation where travel demands exceeds the capacity of the transportation network is known as traffic congestion. However, it is impractical to build more roads and infrastructure to accommodate these demands. Governments are increasingly recogniz...

Vandalism is a type of the so-called low intensity crimes. However, the nuisance and damage caused by it could cost dearly to the public to clean up. It is also technically difficult in the past to detect and prosecute such a crime, for example, graffiti making. This paper presents an automatic and live graffiti detection system using CCTV cameras and innovative vision algorithms. After a brief...

We present a content-based retrieval method for long surveillance videos in wide-area (Airborne) and near-field (CCTV) imagery. Our goal is to retrieve video segments, with a focus on detecting objects moving on routes, that match user-defined events of interest. The sheer size and remote locations where surveillance videos are acquired necessitates highly compressed representations that are al...
