Acoem Gunshot / Threat Detection Problems Tested

By Zach Segal and Derek Ward, Published Aug 11, 2021, 09:39am EDT

Acoem's Acoutstic Threat Detection claims to "protect public spaces with its ability to detect gunshots" and "when a gunshot is heard, our cutting edge technology locates and tracks the threat". But how well did it perform in real world applications?

IPVM Image

In this report, we share our findings from Acoem's Acoustic Threat Detector ATD-301, noting:

  • Common false alert triggers.
  • Indoor/outdoor performance.
  • VMS event and alarm integration.
  • IP camera configuration and limited Web UI settings.
  • List of sounds that did not cause false alarms.
  • Acoem's company profile.
