While false alerts rightfully receives the majority of attention in video analytic performance critiques, these systems must also pass another test - that of balancing the number of false and valid alerts.

VideoIQ provides an example of this in their analysis of baggage left behind problems. Baggage left behind suffers from inevitable false alerts as normal people in public areas temporarily set down their baggage. Additionally, and equally importantly, the likelihood that a bag is really a bomb is extremely low, even in a high risk areas.
