Closed Circuit Television

Аннотация

This book has been written to provide the latter in the above list – a knowledge of CCTV principles and technology. Like the first edition, it uses the City & Guilds/SITO Knowledge of Security and Emergency Alarm Systems syllabus (course 1851) as its basis, making it suitable reading for trainees studying towards this qualification or for those who are working towards an NVQ level II or III in CCTV installation and maintenance. However, to cater for those who are already practising in the industry but who wish to further their technical knowledge and understanding, this second edition includes discussion of such topics as digital video signal compression, digital tape and hard disk recording, and CAT5 structured cabling.
