1. Smart Vision Suite: Analytics Alerts & Searches

2. Use Cases • Use Case: object or behavior to be detected • Person approaching border, Traffic incident, Gate activity, etc. • Alerts are configured and combined to implement a use case • Basic Alert: trigger on simple object or behavior • Object of some Size, Color, Type … • Moving in specific direction, speed or pattern for some duration • Compound Alerts: triggeron more complex behavior • One or more basic alerts that fire in a specific sequence, within some time period

3. Basic Alerts

4. Alert Summary • Motion Detection • Total amount of motion in area • Number of moving objects in area • Directional Motion • Objects moving within range of directions • Abandoned Object • Optimized for bags • Parked Vehicle • Optimized for cars • Object Removed • Specific object • Any object in region • Trip Wire • Variable width increases specificity • Region • Objects starting, stopping, entering or leaving regions • Camera Movement • Motion Start/Stop, Camera Blocked

5. Motion Detection • Use Case Examples: • Area over-crowding • Trigger when 75% of region covered with people • Group Gathering • Trigger when >4 people gather in region for 2 minutes or more • Suitable Factors: • High angle view, uniform or slowly varying lighting, objects (people) do not become completely still • Suitable Image: • Camera Recommendations:

6. Directional Motion • Use Case Examples: • Enter through Exit • Trigger if object path moves wrong way through Exit • Wrong way traffic • Trigger if car drives wrong way in lane • Suitable Factors: • Activity level medium to low, objects do not significantly overlap in image, high angle view (45 degrees or better) • Suitable Image: • Camera Recommendations:

7. Abandoned Object • Use Case Examples: • Bag left on sidewalk / in lobby / near critical infrastructure • Object fallen onto highway • Suitable Factors: • Object > 10x10 pixels minimum • Object contrasts well with background • Object not occluded for > 20% of time or for > 5 seconds at any one time • Suitable Image: • Camera Recommendations:

8. Parked Car • Use Case Examples: • Parked car at critical infrastructure or other area of interest • Suitable Factors: • Medium to low activity • Object must not significantly overlap • Suitable Image: • Camera Recommendations:

9. Object Removed • Use Case Examples: • Monitor critical item • Report when squad car leaves post • Suitable Factors: • Object still for >2 minutes prior to departure • Object at known location or within region • Object never occluded • Suitable Image: • Camera Recommendations:

10. Tripwire • Use Case Examples: • Gate Activity • Triggers when person passes through a gate in either direction • Counting persons entering area • Detect excessive speed • Suitable Factors: • High angle view, minimal traffic parallel to tripwire • Counting: one object at a time • Suitable Image: • Camera Recommendations:

11. Region Alert • Use Case Examples: • Crowd forming • Trigger when >n people remain in region for >t seconds • Loitering • Person remains in region for >t seconds • Car stopped on highway • Trigger when car stops in region for >t seconds • Suitable Factors: • People: Fewer than 10 (best case), medium to low activity, Vehicles: any activity level • Objects must not significantly overlap • Suitable Image: • Camera Recommendations:

12. Face Capture / People Search • Use Case Examples: • Capture face of every person entering building • Search for people using clothing description • Search for people using facial attributes • Suitable Factors: • Clothing: Whole person visible, good color, little occlusion, person > 50 pixels tall • Faces: Frontal face (profile for capture only), 30-60 pixels ear-to-ear • Suitable Image: • Camera Recommendations:

13. Forensic Search Search Criteria Results Display Thumbnails / video Time histogram Track Summary Activity map • Object type • Person, Vehicle • Object Color • 6 color pallet, up to 3 colors per object • Clothing color • Shirt/Pant, 13 color pallet • Size • Speed • Duration in image • Region within image • Facial Features • Bald, (sun)glasses, hair/hat color, shirt color/pattern, skin tone • Time range

14.
