A data value and condition sensing and threat detecting network comprising a plurality of wireless sensor devices and their optional related wireless sub-sensor devices, for communication with wireless detector units in a network arrangement, such wireless detector units to communicate to and from a secure Central Monitoring Unit (“CMU”) that manages the value/condition sensing and client alert processes, based upon wireless sensor values/conditions and optional wireless sub-sensor values/conditions as they relate to pre-determined values/conditions, and sensor device location coordinates data (derived from Global Positioning Systems(“GPS”) or Cellular Triangulation Systems (“CTS”)) as they relate to pre-determined “location differential values”, data “timeframe-based rate of change” as it relates to pre-determined “rate of change differentials” in a pre-determined timeframe or part thereof, and declaring a normal, aware or alert state within a pre-determined timeframe, with the CMU enabling/disabling related devices and alerting responders, and confirming that such related devices have been enabled/disabled and alerts have been delivered, to responders.
