Motion detectors are installed in the room and on some of the storage containers. Fiberoptic loops which serve as electronic seals are placed on lids and the doors are wired with trip switches. Whenever someone enters the storerooms, the detectors take note and start the cameras. Not only does the system reduce the amount of time inspectors must spend visiting sites in person, it also greatly decreases the number of images they must sift through. These cameras turn on only when sensors detect activity.
Older systems use time lapse cameras which record a lot of shots of empty rooms.
If its cheaper, its more reliable, its less intrusive , it makes good common sense. It is not yet linked to a treaty. Meantime, other countries are testing the remote sensing waters as well. As novel as it may sound, participants insist its not revolutionary.
