1. I A I Infrared Security System and Method US Patent 7,738,008 June 15 2010 How Does It Work? June 2010 I A I = Infrared Applications Inc.

2. Test Set-up: Visual Orientation Two cameras with a common surveillance field of view. Camera B can be seen in Camera A’s FOV. Camera A is positioned in Camera B’s FOV Angles between cameras & targets are as shown The Cameras are 105 feet apart.

3. Camera A Target Camera B Location Camera A Angle

4. Camera B Camera A Location Target Camera B angle

5. ISS Geometry Location Camera A Location Camera B Target Planter Location Distance Between Cameras (105 feet) R2 R1 Set up value, distance between Cameras Cameras & target Actual Positions Range computations, R1 & R2

6. Real time calculation of Target Size Cameras are IR calibrated and balanced Gain & Level using common objects Each IR camera employs convention 2 dimensional processing. Target segmentation Threshold Two dimensional information is processed in real time into 3 dimensional information Precise object location (x,y,z, coordinates) Precise physical size (sq. ft)

7. Threat Determination Targets are defined by size –(eg: truck, car, large animal, human, small animal/child, very small animal) A threat is defined as a specific target in a defined location The Location –All or part of surveillance field –Or a specific threat area: No fly zone

8. Target Upgrade & Tracking Target was defined by actual size. Once classified as a threat –Actual the actual target size is stored. –Actual Inherent Thermal Contrast is stored. Threat is continuously tracked by: –Both cameras or one camera if either camera becomes obscured. (2 D tracking using Actual target size for ranging and Inherent contrast for improved discrimination) Continuously tracking: –Allows higher order threat determinations

9. Intruder Example Series of snap shots of an intruder The initial detection is by Camera A. Then, Intruder enters Camera B FOV The intruder enters the yard. The intruder is continuously tracked through partial and total camera obscurations. Snap shots are 1/40 the actual number of independent samples at video frame rates.

10. Camera B, initial detection

11. Camera A ------ Camera B

12. Camera A ------ Camera B Almost fully obscured

13. Camera A ------ Camera B

17. Camera A ------ Camera B Partially Obscured Mostly Obscured

18. Intruder The target alarm sounded approximately 0.5 seconds after Camera B detection. The highly cluttered scene caused each camera to lose the target because of complete or partially obscurations. The “arc” path of the intruder causes an aspect change with small changes in computed size. With more than 300 independent sampled image pairs, the confidence level is extremely high. The Intruder was observed to be carrying a tool or a weapon.

20. Advance Discrimination Techniques Target Refinement: –ITC & Size of each target allows discrimination between targets in a multi-target environment. Target Image Dropout – “Inherent thermal contrast” and actual size are used to re-acquire and separate new targets from old target. Multiple targets: –Can merge together and then separate, where ITC and physical size assigned to each target are used to maintain the identity of each target. Behavioral traits –Movement over time against a preset criteria are associated with a certain kinds of threat. Redundant information – ITC and physical size provides redundant data that support the application of best estimate theory.

21. Advance Discrimination Techniques Designed for multiple targets, each target having a separate threat definition, and threat response. (examples one or more) –“People-size” targets in specific areas at defined times –People congregating (crowd recognition) –Loitering (excessive time) –Stalking, (time history relationship between two targets) –Lying in wait, (serious home evasion threat) –A unattended child entering a swimming pool –Animals entering controlled areas –People exhibiting threatening behavioral –“Man down” recognition –Cars, time and location criteria –Trucks, time and location criteria –People count, matching entering with exits, tagging size –Verification, matching size with independent data, e.g. RFID data

22. Summary Field tests have demonstrated the attributes of the Infrared Security System. ISS provides reliable target detection and threat classification. High level of confidence that all false alarms have been rejected or minimized. ISS has the capability to be the first fully automatic physical security system ISS minimizes or eliminates the costly dedicated control rooms of TV monitors and security analysts. ISS provides the real time information needed by a first responder, or Information needed by the occupants of the home to avoid the threat.

23. ISS Applications Major Business Sectors –Home Security (adjunct to existing home security) –Factories (upgrade from forensic to threat negation) –24/7 High Value (integrated threat assessment) Power Plants Refineries Farms (man and environmental threats, seasonal threat) Military Installations & portable field operations Shopping Malls, parking lot security (host of threats) Airports: intrusion, unattended luggage, & threat tracking Green Applications –Automobile Sales lots –Correctional Institutions –Transportation Depots/shipyards/docks Other forms employing the core patented principle of 3D processing
