Glassbreak alarm recorder for false alarm verification

Abstract

A glass breakage detector () having an acoustic transducer () for sensing first acoustic waves () and for providing a first analog signal () representative of the received first acoustic waves (), an analog to digital converter circuit () adapted to convert the first analog signal () to a digital signal (), processing circuitry () adapted to process the digital signal () to determine if the received first acoustic waves () are a result of glass breakage and generate an alarm signal () when it is determined that the received first acoustic waves () are a result of glass breakage, and a memory circuit (), wherein the processing circuitry () is adapted to cause the memory circuit () to store the digital signal () for subsequent retrieval and analysis.
