1. A system for monitoring an area containing sited assets and alerting to the presence and location of gunfire, said system comprising:
an arrayed network comprising at least two sensors, each of said sensors comprising a microphone, a microcontroller comprising non-volatile memory, a battery, a wireless transceiver and an antenna;
a central device comprising a wireless transceiver and an antenna configured for communication with said sensors, said central device further comprising a microprocessor functional to access non-volatile memory, said central device further comprising a communication port operable to supply gunshot location information to a destination;
wherein each of said sensors is operable to:
(a) monitor the audio energy in its vicinity,
(b) take repeated samples from said microphone and compute at least one energy value, and
(c) wirelessly transmit a gunshot candidate to said central device comprising the computed energy values;
further wherein said central device is operable to:
(d) receive gunshot candidates each comprising at least one energy value,
(e) correlate gunshot candidates arriving from both sensors to single potential gunshot events,
(f) derive a ratio from a comparison of the energy values within correlated gunshot candidates,
(g) from derived ratios of energy values, calculate potential locations of a gunshot event, and
(h) communicate gunshot location information to a destination, over said communication port;
wherein said central device is located within wireless communication range of each of said sensors.
