 28% (70/250) of max gain  Counting is 3259/min  69% of the max gain  Counting is 900/min (15/Sec) DayCor ® CoroCam  Test conditions  Same day and time  Identical source  Identical distance Play Click to Play Comparison test - Results Click to Play

DayCor ® Gain 2.4 times lower DayCor ® count 3.6 times higher Outcomes and Conclusions DayCor ® sensitivity - 9 times higher

Sensitivity Comparison [ Watt/cm^2] DayCor ® High 3x CoroCam Low 8x Ofil can detects 1.5 pC from a distance of 8m at normal video rate (25 or 30 frames/sec) without any image processing. DayCor® Vs CoroCam DayCor® Vs CoroCam

 Large efficiency collection area  High quality solar blind filter  Strong and sensitive MCP  Narrow FOV - Filed Of View DayCor ® has the highest sensitivity due to: Feature - Sensitivity

Feature - Long Integration Low frame rate lingered shots of each scene Used by CoroCAM to compensate for low sensitivity Must use a tripod Slow inspections – unfit for airborne nor driven

Feature - Long Integration Recommended to: 1. Overcome background disturbances/noise Not recommended: 1.Smearing picture 2.Lingered inspection 3. Tripod required. Click to Play
