© 2012 IBM Corporation Staged Event testing Needed when wild events are rare Customer stages events As many as reasonable Revisit cameras when possible IBM evaluates results and tunes as needed Options – depends on customers needs All cameras or Sample ? Only after FP tuning ? Cause to Reject Camera ? Absolute performance numbers unreliable without large numbers of events !

© 2012 IBM Corporation Typical Alert tuning success rate 70% deployed with minimal reduction in Hit Rate –35% minimal tuning (1-2 iterations) –15% with moderate tuning (2-3 iterations) –15% where tuning has minor HR impact 15% could be deployed with more severe HR impact 15% will be rejected
