Security and tracking system

   
   

A security and tracking apparatus includes at least a first signaling unit and a second signaling unit in communicating proximity with the first signaling unit, each signaling unit having a receiver for identifying the location of the signaling unit; and, a transmitter for transmitting the location of the signaling unit when the first and second signaling units are separated by more than a preselected distance. A method to locate a person, animal, or object, includes providing in contact with or at least in close proximity to the person, the animal, or the object, at least a first signaling unit and a second signaling unit, the second signaling unit in communicating proximity with said first signaling unit, each signaling unit having a receiver for identifying the location of the signaling unit and a transmitter for transmitting the location of the signaling unit when the first and second signaling units are separated more than a preselected distance; and activating the signaling units to transmit the location of the signaling units.
