This paper presents the extension of previous proposed work of abandoned object detection in real time system [1]. Recently the use of CCTV cameras for security purpose is increased . All the public places are now under the CCTV. Now state government has also made it compulsory to use CCTV for cooperative housing societies. This work is done to give the good quality abandoned object detection t...

Findings from the current UK national research programme, MEDUSA (Multi Environment Deployable Universal Software Application), are presented. MEDUSA brings together two approaches to facilitate the design of an automatic, CCTV-based firearm detection system: psychological—to elicit strategies used by CCTV operators; and machine vision—to identify key cues derived from camera imagery. Potential...

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...

Despite the increased usage of surveillance systems and the technological advances, there is currently no conceptual basis and little evidence to assess how well CCTV actually works for the purposes for which it is deployed. It is important to identify whether CCTV systems and applications meet stakeholder goals, and support human operators effectively, in attaining the goals for which the syst...

OBJECTIVE To evaluate the effect of city and town centre closed circuit television (CCTV) surveillance on violence in terms of accident and emergency (A&E) department and police assault data. METHODS A&E department and local police assault data in three centres in Wales (Cardiff, Swansea, and Rhyl) two years before and two years after the installation of CCTV were studied. British Crime Surve...

In recent times, crime rate in Nigeria has risen to the level in which there are public outcries urging government for urgent and concrete solutions. Government has adopted various security policies to secure the lives and properties of its citizens, but none of these policies have actually yielded positive results. Human abduction, armed robbery, terrorism, bomb attacks and lots more have been...

CCTV is used for an increasing number of purposes, and the new generation of digital systems can be tailored to serve a wide range of security requirements. However, configuration decisions are often made without considering specific task requirements, e.g. the video quality needed for reliable person identification. Our study investigated the relationship between video quality and the ability ...

Situational crime deterrence measures like CCTV are not always associated with reductions in fear of crime. This study explores this unexpected finding by investigating the interaction between target type and the presence of a CCTV camera, in order to test the effect this has on impressions of the target and corresponding fear of the location the target was shown in. Participants (n=120) were s...

Simultaneous video (closed circuit television [CCTV]) and EEG recordings are important in the differentiation of epileptic and non-epileptic paroxysmal episodes and in the classification of epilepsy syndromes. An additional benefit from the observation of the child on CCTV is the possible identification of specific clinical, including genetic, conditions. This three-year prospective study of 27...
