Domestic drone detector will alert users to airborne spies

Worried about drones spying on you? Soon, a device might be able to send you text and email alerts that let you know when a drone is nearby.

A Washington, D.C.-based engineer is working on the “Drone Shield,” a small, Wi-Fi-connected device that uses a microphone to detect a drone’s “acoustic signatures” (sound frequency and spectrum) when it’s within range.

The company’s founder, John Franklin, who has been working in aerospace engineering for seven years, says he hopes to start selling the device sometime this year. He is using the Kickstarter-like Indiegogo to finance the project.
