The HALO Smart Sensor learns the signature of abnormal noise in a room by applying machine learning. The HALO learns what normal sound levels are and alerts when a threshold above normal is detected for a specified length of time. HALO applies aggression detection through true analytics.

False aggression events can occur if there are significant changes in the environment. For example, our customers that have HALO’s installed in schools, the noise level during Summer break vs. the start of the school year varies greatly. If a false event is triggered, please contact support so we can review your logs and thresholds settings and recommend the optimal configuration for HALO.
