A system that once merely required cameras, cabling, and video monitors has now become a complex electronic confi guration of equipment intertwined with both computer and telecommunications technologies. This dramatic change is directly related to the introduction of digital technology. Why do we need to understand how digital technology works, and what does it have to do with the future of security? It’s simple—the newest revolution in technology is pervasive computing. Computers are or soon will be everywhere, linked to everything, and everything will be connected by the Internet—including security systems. Upheavals within the electronics industry have been persistent and are well known. For example, most everyone remembers how eight track players were relegated to the trash heap without so much as a backward glance. Phonograph records were shut out by compact discs and the consumer VCR has virtually been replaced by the DVD player. In the security industry, the revolution from analog to digital is similar to these earlier advancements and will probably be looked at with the same amount of disdain regarding archaic processes of the past. Digital technology is exploding around us, yet a large amount of industry professionals are still looking for a comprehensive explanation of digital video as a security technology. Security professionals today understand how the components of a CCTV system work. They know the applications, limits, strengths, weaknesses, and relative costs of lenses, cameras, camera mounts, pan/tilt units, and housings. Such knowledge enables professionals to design systems and to select from a myriad of products just the right components, resulting in a CCTV system that will meet customer performance requirements and budgets. There is, however, a concern that digital CCTV equipment concepts have not been adequately explained. The reality is that digital technology is much more than a trend and requires a rather extensive learning process if one can intelligently buy, sell, install, or recommend digital video products. In today’s environment, it is essential for the security professional to know how the Internet works and how LANs and WANs function in relation to the World Wide Web. 本资源链接共6个可选网络硬盘链接，2.94 MB。 -------------------------------------------------------------------------------------------------------- 2.94 Digital CCTV_A Security Professional's Guide.9780750677455.p328.Butterworth-Heinemann.2007.rar https://rapidshare.com/files/389 ... -Heinemann.2007.rar https://uploading.com/files/3a9b ...
