Forget the spy cameras, scent-detectors, and data-mining algorithms. An Oak
Ridge National Laboratory group is looking to build a laser-based
surveillance system to "automatically detect millimetre-scale changes to a
scene."

"Rather than detecting intruders or monitoring people, it keeps track of
static objects in a scene. This is done by attaching tags to important
items, which reflect laser light, allowing a connected sensor to monitor
their location precisely," New Scientist observes. "If one of the tags is
moved, or disturbed even slightly, this will be revealed by the laser
reflection."

Note: While I'm very delighted by the technology :-) I have to say
that between this and RFID Dust [1], some of this technology also
kind of disturbs me a little.
