The Vallejo Sanitation and Flood Control District is performing CCTV inspections on pipes that do not have a record of such inspections. This effort was triggered by a settlement with Baykeeper, who alleged that broken pipe or pipe about to collapse would remain undetected and lead to sanitary sewer overflows. The actual result of the CCTV inspection turned out to be quite different. Instead of...

Perception of scenes has typically been investigated by using static or simplified visual displays. How attention is used to perceive and evaluate dynamic, realistic scenes is more poorly understood, in part due to the problem of comparing eye fixations to moving stimuli across observers. When the task and stimulus is common across observers, consistent fixation location can indicate that that ...

This paper explores in which ways privacy (in particular, data protection principles) comes to the fore in the day-to-day operation of a public video surveillance system. Starting from current European legal perspectives on data protection, and building on an empirical case study, the meanings and management of privacy in the practice of Closed-Circuit Television (CCTV) will be discussed in ord...

In this research, image analysis was used to optimize the visual output of a traditional Closed Circuit Television (CCTV) magnifying system and a head-mounted display (HMD) for people with low vision. There were two purposes: (1) To determine the benefit of using an image analysis system to customize image quality for a person with low vision, and (2) to have people with low vision evaluate a t...

This collection of articles forms the second part of a double Special Issue of Information Polity devoted to the subject of surveillance cameras and systems, often referred to here as CCTV (Closed Circuit Television). Part One was previously published as Volume 16, Number 4, in 2011. Part Two features two articles, three case studies and two surveillance-themed book reviews. Studying a diversit...

Given that the number of CCTV cameras in the UK is the largest in the world, and given that it is unclear when video data should be regarded as Personal Data (or what rights a blanket definition would reasonably provide to the surveilled) it is claimed that a CCTV Act is needed in the UK. This claim appears to be supported by the police authorities [Bal06a], although in addition to a broad clai...

The objective of this investigation is to produce recommendations for acceptable bit-rates of CCTV footage of people onboard London buses. The majority of CCTV recorders on buses use a proprietary format based on the H.264/AVC video coding standard, exploiting both spatial and temporal redundancy. Low bit-rates are favored in the CCTV industry but they compromise the image usefulness of the rec...

Sometimes a simple and fast algorithm is required to detect human presence and movement with a low error rate in a controlled environment for security purposes. Here a light weight algorithm has been presented that generates alert on detection of human presence and its movement towards a certain direction. The algorithm uses fixed angle CCTV camera images taken over time and relies upon skeleto...
