Security Electronics Circuits Manual is an invaluable guide for engineers and technicians in the security industry. It will also prove to be a useful guide for students and experimenters, as well as providing experienced amateurs and DIY enthusiasts with numerous ideas to protect their homes, businesses and properties. As with all Ray Marston's Circuits Manuals, the style is easy-to-read and non-mathematical, with the emphasis firmly on practical applications, circuits and design ideas. The ICs and other devices used in the practical circuits are modestly priced and readily available types, with universally recognised type numbers. This title replaces the popular 'Electronic Alarm Circuits Manual'. Ray Marston has proved, through hundreds of circuits articles and books, that he is one of the leading circuit designers and writers in the world. He has written extensively for Popular Electronics, Electronics Now, Electronics and Beyond, Electronics World, Electronics Today International, Nuts and Bolts, and Electronics Australia, amongst others.
