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.
