1. An autonomous threat response system, the system comprising:
a communication network;
a first microphone and second microphone system communicatively coupled to the communication network;
a first autonomous non-flying (ANF) drone communicatively coupled to the communication network, the first ANF drone and the first and second microphone systems are positioned at different locations of a protected area, wherein the first ANF drone comprises a third microphone; and
a threat response controller communicatively coupled to the communication network, the threat response controller configured to:
monitor an acoustic event coming from the protected area, using the first and second microphone systems and the third microphone, to determine an origin of the acoustic event using trilateration;
determine a threat level of the acoustic event based on an audio profile of the acoustic event;
dispatch the first ANF drone to the origin of the acoustic event to investigate based on the determined threat level and a predetermined social value of the origin of the acoustic event; and
a plurality of acoustic beacons disposed at known locations in the protected area, each of the beacons is configured to transmit distinct audio signals, wherein the first ANF drone is configured to determine its location with respect to the plurality of acoustic beacons based at least on the distinct audio signals.
