How does the false alert rate of a standard/typical metal detector compare?
Evolv's False Alarm Rate Ranges From 5 To 60%
Published May 25, 2022 14:38 PM
While Evolv markets that it "eliminates friction" and provides "touchless screening" with its system, IPVM estimates that Evolv Express' false alert rate is 5-10%. (Update 2023: Evolv's false alarm rate has ranged from 5% to 60%, and this article has been updated.)
This can be good or bad, depending on the application. Inside this report, IPVM analyzes this false alert rate in various applications and its impact on system deployment.

May 26, 2022The false alert rate of a traditional metal detector can vary, but it is typically higher than Evolv's. For example, the report mentions a 40% alert rate on the Mercedes Benz Stadium.

May 27, 2022So up to the customer to determine is 30-35% less false alerts is worth it to them. I can see Evolv's pitch work out easily there, cut your staffing to pay for the "more advanced" metal detector.

May 27, 2022cut your staffing to pay for the "more advanced" metal detector.
Many venues and locations are short staffed to begin with - so it wouldn't necessarily translate to cost savings. i.e. - the facility is not laying off people when they are already short / cant find help - so payroll may not be impacted.

May 27, 2022Yes, that's what we said in the article above, copied below:
Evolv Express is proving to be successful in facilities that already screen for weapons with conventional metal detectors, as Express significantly reduces false alarms, which reduces labor costs.
