1. A remote monitoring device for monitoring and managing by a monitoring service via a communications network a condition of an automated external defibrillator (AED) based on audio signals from the AED, comprising:
a housing configured to be positioned outside of the AED such that audio sounds from the AED can be detected, the housing containing:
at least one processor;
a communications module operably connected to the at least one processor and configured to transmit electronic communications to the monitoring service via the communications network;
at least one audio sensor;
at least one audio detection circuitry operably connected to one or more of the at least one audio sensor and the at least one processor, the at least one audio detection circuitry configured to:
generate a notification signal when detecting audio sounds during a predetermined detection interval, and
commence an active listening mode to provide digital audio signals to the at least one processor in response to the notification signal,
wherein the at least one processor is configured to power on in response to the notification signal, process the digital audio signals, and transmit a signal to the monitoring service to report a condition of the AED based on the digital audio signals that are processed.
