A virtual perimeter system for determining a position of a mobile device relative to a virtual perimeter, comprises: a plurality of transmitters configured to broadcast a unique identifier; a management platform for storing positional data for each transmitter; and a mobile application for installation on a mobile device. The management platform is configured to communicate with the mobile application. The transmitters are positioned to define the virtual perimeter around a target entity. The management platform is configured to: (a) map the perimeter dependent upon the positional data; (b) receive transmitted data from the mobile application when it detects the unique identifier the transmitters and determine a proximate location of the mobile device; and (c) send an alert to the mobile application for display on said mobile device. The perimeter comprises a perimeter profile stored on the management platform comprising target entity information having a mobility status of the entity. |
