Audio Analytics Aggression Tested

Author: Ethan Ace, Published on Nov 20, 2015

What if you could use your IP cameras to detect fights before they start? 

That is the goal of Louroe / Sound Intelligence with their recently released Aggression Detector audio analytics. Claiming that "90% of physical aggression are preceded by verbal aggression", these analytics are designed to alert guards before verbal altercations turn physical.

We tested the Aggression Detector using both live subjects and recorded clips of multiple scenes, to see just how these analytics perform.

Here is the app main view that we used to monitor and optimize the audio analytics:
