Passive InfraRed PositioningCar‐tracking with SPIRIT 

The passive infrared ( PIR ) sensors used in the security industry have reachedtheir technical limits .Since 35 years , the manufacturers have improved only the traditional optics and the signal processing but NEVER THE PHYSICAL PRINCIPLE OF THE OPTIC which can transform a PIR into a geolocator . The advantages of PIR sensors are reliability in detection, low consumption, lowcost, easy installation. To‐day the weak point is the lack of information for VideoManagement Systems ( VMS) or Video Analytics softwares such as geolocation.Let us introduce an innovative PIR geolocator using a new and patented opticalphysical principle : SPIRIT.

SPIRIT :Smart Passive InfraRedIntrusion,location and Tracking

The 15 fields of view of the SPIRIT have been superimposed on the scene . The first event ( the car ) and its location is sensed in the field of view #15.The SPIRIT transmits immediately the location to the Pan Tilt Zoom (PTZ) camera dome which points then towards the approaching car.
