Accellfx proximity detection system

A security system, comprising:

• a plurality of monitoring devices, wherein the monitoring devices each includes a transmitter to emit one or more signals containing a unique identifier associated with the monitoring device and other status information;
• one or more proximity sensors at a first known location configured to detect the one or more signals emitted by the monitoring device and transmit said unique identifier and other status information;
• a transmitter configured to relay the one or more signals from the one or more proximity sensors to a security panel;
• and
• the security panel, wherein the security panel generates an alert that one or more of the proximity sensors no longer detects the one or more signals emitted from the monitoring device;
• wherein the monitoring device is wearable and/or attachable to a dependent;
• wherein the one or more proximity sensors are placed at one or more known location of the dependent;
• wherein the alert generated by the security panel includes a threat level that increases in intensity as the monitoring device moves away from the one or more proximity sensors located at one of the known locations of the dependent;
• wherein a second set of one or more proximity sensors are located at a second known location and configured to detect the one or more signals emitted by the monitoring device and transmit said unique identifier and other status information to a security panel;
• and
• wherein the security system defines a wireless tether to the dependent to track the location of said dependent between the known locations of the dependent.

A method of tracking a person of interest, comprising:

• attaching or securing a monitoring device to the person of interest;
• detecting the presence of one or more signals generated by the monitoring device via one or more proximity sensors at a first location, wherein the signals include status information associated with the monitoring device;
• transmitting the one or more signals and the status information from the one or more proximity sensors to a security panel via a transponder;
• and
• generating an alert via the security panel when the one or more proximity sensors start detecting signals emitted from the monitoring device and/or when the one or more proximity sensors cease detecting signals emitted from the monitoring device;
• wherein the one or more proximity sensors are programmed to detect signals generated by a plurality of monitoring devices;
• wherein the one or more signals generated by the monitoring device are detectable by proximity sensors located at a second location;
• and
• wherein the security panel is configured to communicate with one or more other security panels in order to send potential threat notifications to said one or more other security panels.
