Abstract:
1. A telemetry system for signaling occurrence of a first event at a first location, comprising: an “always on” network; a first sensor communications device communicatively connected to the “always on” network, capable of detecting occurrence of the first event at the first location, the first sensor communications device capable of directly communicating over the “always on” network, the first sensor communications device has a first unique identifier; a central host communications device communicatively connected to the “always on” network, the first unique identifier uniquely recognized by the central host communications device as corresponding to the first sensor communications device; a first symmetric key maintained by both the central host device and the first sensor communications device, employed in securing communications over the “always on” network between the first sensor communications device and the central host communications device; wherein the first sensor communications device, on occurrence of the first event at the first location, indicates the occurrence of the first event by securely communicating over the “always on” network to the central host communications device; wherein the central host communications device uniquely recognizes the first event as occurring at the first location because of the first unique identifier of the first sensor communications device.
