an alarm to be triggered if the object enters the at least one policy region but not if the object exits the at least one policy region;

an alarm to be triggered if the object exits the at least one policy region but not if the object enters the at least one policy region; or

an alarm to be triggered if the object enters the at least one policy region from a first side of the at least one policy region and exits the at least one policy region from a second side of the at least one policy region.

13. The system of claim 12 wherein the one or more sensors provide sensor data to the controller in world coordinates.

14. The system of claim 12 wherein the processor is configured to convert sensor data from the one or more sensors into world coordinates.

15. The system of claim 12 wherein the one or more alarm criterion of at least one of the policy regions cause an alarm to be triggered if the object enters the at least one policy region but not if the object exits the at least one policy region.
