In Brief

Drone Shield identifies characteristic acoustic signatures of different kinds of drones, sounding an alarm when a threat is looming.

Privacy has always been a matter of concern when drones come up in daily conversation, but one start-up has found the solution to avoid potential security breaches. Already a funded Indiegogo campaign, the Drone Shield is a portable black box that listens for drones in the air, and alerts its owner if one is flying near.

Designed to pick up sounds that we can’t hear with the naked ear, this drone-detecting device can identify the characteristic acoustic signatures of different kinds of drones. It is accurate enough to ignore ambient noise created by loud gardening equipments, like lawn mowers and leaf blowers.
