Electronic security systems

Comprehensive coverage of electronic security systems Written by an experienced security professional Fully updated to examine new equipment Gives extensive help on avoiding false alarms 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.
