Closed Circuit Television (CCTV) surveillance remains a growing industry in response to increased security threats, and whilst new developments have brought clearer images, digital recording and high speed data transmission, effective security systems still rely upon proper specification and installation by engineers with an in depth knowledge of CCTV principles and technology. The third edition of Closed Circuit Television provides a thorough technical guide for all those involved in the design, specification, installation and maintenance of CCTV systems. Fully dual-standard for PAL and NTSC systems, the book covers the essential equipment and topics of relevance to practitioners, managers and students on vocational and industry training courses. Extended coverage of flat screen devices, digital recording, and a new chapter on networking principles, bring this popular guide up to date with the latest developments in the field. Joe Cieszynski is a well-known technical writer with a wealth of experience in the security industry. After many years of college lecturing on TV, video and security topics, he currently acts as City & Guilds' Chief Examiner for security systems and provides independent CCTV system consultancy.
