Abstract
A monitored space is monitored including the production of a first audio signal from received acoustic energy. The first audio signal is then processed against a whitelist of acoustic profiles and, based on lack of substantial correspondence with any of the acoustic profiles, a drone is navigated toward an apparent position of an apparent source. While in-flight, additional acoustic energy is received and a second audio signal is produced from the additional acoustic energy. The second audio signal is processed against the whitelist and, based on lack of substantial correspondence with any of the acoustic profiles of the whitelist, an investigate mode of the drone is initiated. The investigate mode includes notifying a remote monitor and supplying the remote monitor with an audiovisual feed. Responsive to a characterization by the remote monitor, an entry of the whitelist may be updated, added or replaced.
