The device’s overall operation is to detect and alert the user of a drone once it enters the vicinity of a protected environment. It functions by listening for the sound signature a drone emits when flying towards a target.
When a drone approaches a protected space, the device will recognize the drone sound and will proceed to track it. It does this while simultaneously alerting the owner of the incoming threat’s location. By doing so, the user can act to stop any imminent breaches of privacy or safety.
