Never mind multimil $$$ budget items. Doors can be wired with alarms. Door not shut for selected time, then audible/visual alarms. Legitimate movement of bodies thru the door, alarms disabled while coded key within range. That is, there must be an authorized key holder within say Bluetooth range. That puts the authority figure in close proximity to the door. What did I miss?
