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;
a first audio sensor;
a first audio detection circuitry operably connected to the first audio sensor and the at least one processor, the first audio detection circuitry configured to generate a wakeup notification signal when the first audio detection circuitry detects audio sounds during a predetermined detection interval;
a second audio sensor; and
a second audio detection circuitry operably connected to the second audio sensor and the at least one processor, the second audio detection circuitry configured to power on in response to the wakeup notification signal and commence an active listening mode to provide digital audio signals to the at least one processor,
wherein the at least one processor is configured to power on in response to the wakeup 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.
