In the latest edition, Philip Walker not only tackles the electronic aspect of the design of a security system, but also examines the human factor in such systems. In his own words: 'Electronic aids are added to enable security officers to do their jobs better, but not to do their jobs for them'.
Today, with the escalation of crime and growing concerns for security, there has been a great increase in the number of electronic security systems. Unfortunately, despite improvements in reliability in terms of equipment manufacture, false alarms do still occur, and they waste a large amount of police time; approximately ninety out of one hundred alarms investigated by the police are false. In the light of this, the new edition of Electronic Security Systems couldn't come at a better time, as it deals extensively with methods of reducing false alarms, allowing the police to concentrate on real breeches of security, and thus ultimately to reduce crime.
The extensive and unusual combination of experience that Philip Walker has in the world of electronics, communications and as a security consulting engineer makes him eminently qualified to tackle such subjects.
At only 30, this hardback book is an essential addition to your security collection. It has 320 pages packed with advice and technical knowledge, 40 photographs and 25 line diagrams and a good index.

"For so long we were floundering and taking ad hoc measures, but the minute I understood what a downtown plan really was I said 'We need one of those!' As it turned out, it was the most fantastic vehicle I've ever seen," said Susan Moffat-Thomas of New Bern, North Carolina. Her hometown got a much-needed shot in the arm from a good downtown plan. Does yours need a similar boost? The Author, an experienced downtown-planning consultant, offers practical tips for preserving a sense of place, improving fiscal efficiency, and enhancing quality of life in Downtown Planning for Smaller and Midsized Communities. Planners and revitalization officials will learn how to address physical components of the downtown, as well as economic development. The Author, an experienced downtown-planning consultant, also explains how to develop an organization to implement a downtown plan; how federal, state, and local policies may influence the planning process; and how to fund a downtown revitalization effort.

" Doris Ulmann (1882-1934) was one of the foremost photographers of the twentieth century, yet until now there has never been a biography of this fascinating, gifted artist. Born into a New York Jewish family with a tradition of service, Ulmann sought to portray and document individuals from various groups that she feared would vanish from American life. In the last eighteen years of her life, Ulmann created over 10,000 photographs and illustrated five books, including Roll, Jordan, Roll and Handicrafts of the Southern Highlands. Inspired by the paintings of the European old masters and by the photographs of Hill and Adamson and Clarence White, Ulmann produced unique and substantial portrait studies. Working in her Park Avenue studio and traveling throughout the east coast, Appalachia, and the deep South, she carefully studied and photographed the faces of urban intellectuals as well as rural peoples. Her subjects included Albert Einstein, Robert Frost, African American basket weavers from South Carolina, and Kentucky mountain musicians. Relying on newly discovered letters, documents, and photographs -- many published here for the first time -- Philip Jacobs's richly illustrated biography secures Ulmann's rightful place in the history of American photography.

How did John Calvin understand and depict God's relationship with humanity? Influential readings of Calvin have seen a dialectical divine-human opposition as fundamental to his thought. As a result, the importance of the doctrine of the Trinity in his understanding of the divine-human relationship has been largely overlooked. In this fresh consideration of Calvin's Christian vision, however, Philip Butin demonstrates Calvin's consistent and pervasive appeal to the Trinity as the basis, pattern, and dynamic of God's relationship with humanity. Butin examines the historical background, controversial context, and distinctive features of Calvin's Trinity doctrine. He then explores the trinitarian character of Calvin's doctrines concerning revelation, redemption, and human response to God. Finally, his consideration of Calvin's doctrines of the church, baptism, and the eucharist suggests the contextuality, comprehensiveness, and coherence of Calvin's trinitarian vision.
