Tamil Nadu: A technology that can precisely detect the source location of a random gunshot and direct a drone or Unmanned Aerial Vehicle (UAV) to the spot for capturing live visuals was successfully tested at the Tamil Nadu Police Academy.

As commandos fired gunshots from different locations near Vandalur, K. Senthil Kumar of the Madras Institute of Technology (MIT) and his team of researchers used an advanced acoustic sensor to calculate the coordinates of their location. Besides gunshots, the customised sensor can detect specific sounds, such as the noise of a jeep in a forest. “If a sniper fired a bullet from an unknown location at a VVIP in a crowded place, the acoustic sensors, if installed in the vicinity, could instantly detect the place from where it was fired” said Dr Kumar. Drones fitted with cameras and acoustic sensors can be deployed along borders, forests and inaccessible terrains to monitor the movement of unauthorised persons. The sensors can also be installed on vehicles, buildings and lampposts. Multi-sensor approach would yield much more effective results.
