Abstract:
A security system comprising an audible alarm with a microphone within acoustic range of the audible alarm. A storage circuit configured to store at least one acoustic fingerprint. A processing circuit coupled to the storage circuit and configured to create a first acoustic fingerprint from a first signal from the microphone and save the first acoustic fingerprint on the storage circuit. The processing circuit further configured to create a second acoustic fingerprint from a second signal from the microphone and compare the first acoustic fingerprint to the second acoustic fingerprint. The processing circuit further configured to transmit a set of data if the first acoustic fingerprint matches the second acoustic fingerprint. A transmitter coupled to the processing circuit and configured to transmit the set of data. The security system has the advantage to be installed without using wire connections to existing alarm systems or decode their radio frequencies.
