Abstract
A device directed to providing for a means for a security or alarm system to detect a measured deviation in the ambient decibel level in the monitored area indicating that vehicles or equipment are being cranked and started at a time when they should not be. The measurement of a predetermined variance in the decibel level can invoke notifications, sirens and the video taping of the area in order to deter the theft. This invention may be an option added to any existing security system as an article of intermediate manufacture. In addition to decibel level detector feature, each vehicle's running engine sound can be loaded into the security system which, similar to a voice recognition system, allows the security system to identify which vehicle is being started.
Claims7
An alarm system, comprising:
- a device operable to measure ambient decibel level during specified times either during working hours or after working hours, wherein the device records the ambient decibel level and maintains a historical data base of an average hourly decibel level and an average decibel level over a specified monitored period and keeps a running average decibel level over at least a portion of an entire duration of a operable life of the device;
- and
- a security feature which detects and measures sounds relative to ambient decibel level within an environment in which said sounds are detected and measured and which detects increases in said sounds exceeding the ambient decibel level by a specified decibel level increase sustained for a specified pre-set time of 1 second or longer.
