Gunshot Detection Wearable

Sensors, Internal Exploratory Project

Initiated September 2023, Completed March 2024

This internal concept explored how embedded sensors and real-time ML inference might offer frontline officers a critical safety net in high-stress engagements. Built around a 9-axis IMU and directional microphone, the wrist-worn prototype was trained to detect and classify the unique audio-kinematic signature of nearby gunfire. The goal: eliminate the delay—or complete absence—of manual backup requests after shots are fired. With an automatic escalation path to dispatch, the system aimed to buy time when seconds matter most. Field recordings, vibration profiles, and feature extraction informed a lightweight model capable of running locally on the device.
