CCTV for Wildlife Monitoring is a handbook on the use of CCTV in nature watching, conservation and ecological research. CCTV offers a unique ability to monitor wildlife in real time, stream video to the web, capture imagery of fast-moving species or cold animals such as wet otters or fish and maintain monitoring over long periods of time in a diverse array of habitats. Wildlife watchers can take advantage of a huge range of CCTV cameras, recording devices and accessories developed for use in non-wildlife applications. CCTV allows intimate study of animal behaviour not possible with other technologies. With expert experience in engineering, photography and wildlife, Susan Young describes CCTV equipment and techniques, giving readers the confidence to tackle what initially may seem technically challenging. The book enables the reader to navigate the technical aspects of recording: basic analogue, high definition HD-TVI and IP cameras, portable CCTV, digital video recorders (DVR) and video processing by focusing on practical applications. No prior knowledge of CCTV is required – step-by-step information is provided to get anyone started recording wildlife. In-depth methods for recording foxes, badger, deer, otters, small mammals and fish are also included, and the book makes comparisons with trail cameras where appropriate. Examples of recorded footage illustrate the book along with detailed diagrams on camera set-ups and links to accompanying videos on YouTube. Case-studies show real projects, both the equipment used and the results. This book will be of interest to amateur naturalists wishing to have a window into the private world of wildlife, ecological consultants monitoring protected species and research scientists studying animal behaviour.

Many liberals consider CCTV surveillance in public places - particularly when it is as extensive as it is in England - to be an infringement of important privacy-based rights. An influential report by the House of Lords in 2009 also took this view. However there has been little public, or academic, discussion of the underlying principles and ethical issues. What rights of privacy or anonymity do people have when abroad in public space? What is the rationale for these rights? In what respect does CCTV surveillance compromise them? To what extent does the state's interest in crime prevention warrant encroachment upon such privacy and anonymity rights? This book offers the first extended, systematic treatment of these issues. In it, the author develops a theory concerning the rationale for the entitlement to privacy and anonymity in public space, based on notions of liberty and dignity. She examines how CCTV surveillance may compromise these rights, drawing on everyday conventions of civil inattention among people in the public domain. She also considers whether and to what extent crime-control concerns could justify overriding these entitlements. The author's conclusion is that CCTV surveillance should be appropriate only in certain restrictively-defined situations. The book ends with a proposal for a scheme of CCTV surveillance that reflects this conclusion.

Central state and non-covert surveillance began in earnest at the start of the twentieth century. By the start of the twenty-first century, the UK was one of the most surveilled societies on earth. This groundbreaking volume by Inga Kroener analyses the particular combination of factors that have created this surveillance state. Kroener argues against the inevitability of the rise of CCTV that is so often found in this literature, to map out the early history of CCTV, tracing its development from a tool for education, safety and transport during the 1950s, to one of politics in the 1970s and 1980s, to eventually become a tool of surveillance during the 1990s. Within this analysis, the complex role of the public in 'allowing' the widespread and rapid dissemination of CCTV is discussed and the representation of CCTV in the media is also studied. This volume will be of interest to all scholars working in the fields of surveillance studies; science, technology and society departments; and social historians more generally.
