Method and means for reducing false alarm rates in security systems |
摘要 |
The false alarm rate of security systems is reduced by utilizing information generated immediately prior to the activation of alarm means. This information is stored in recording means such as a magnetic tape recorder. The recorded information may be later transmitted to a remote site to help in judging the validity of an alarm.
