Evolv Maryland School Customer Satisfied Despite 250:1 False Alarm Rate
An Evolv school district customer told IPVM that they are satisfied with the system and that "without this technology [the school official] 100% believe we would have had a school shooter" incident.
However, statistics from the school district show that in the past school year there were 250+ false alarms for every 1 verified, even after workarounds for Chromebooks.
Inside this note, we examine the statistics and the full response from the school, examining what this signifies for the demand for such systems in schools.
