Movement Sensors a Less Invasive Alternative To CCTV

holy_calamity writes "Researchers at Mitsubishi say cramming buildings with movement sensors, not cameras, is a safer and less invasive alternative to CCTV. They covered their office building with 215 low-cost sensors to watch over their colleagues and show how it works. A video shows how a user can see people's movements on a map of the building in real time. Data from the sensors is much easier to handle than video footage, and it can easily be searched." The Surface-like UI is pretty neat too.

RTFA: They will mainly use motion sensors and place cameras in strategic locations so they can go back and track a particular person if they need to. It doesn't seem like a good implementation for a method of time-sensitive tracking to me, plus in a crowd situation it's pretty useless. I may be wrong but it sounded like it was more a way of studying movement behaviors rather than pure individual tracking.

The fact that you have a UID of 56 and still don't have excellent karma says something about the quality of your opinions. Your intarweb is broken... my karma is Excellent.
