Quick and easy idea...for alarm systems.
Make x number of machines, that once you leave the perimeter it activates alarms. For example I have a family of four. All 4 have this device in their wallet in whatever way. If none of the 4 devices are in the perimeter alarm is active, if any 1 of the 4 devices are in the perimeter the alarm is dis-activated. |
