Drones are everywhere in America these days, from sports arenas to movie sets — even the White House lawn. It's clear they've gone mainstream, but the reality is, they're not always welcome.
DroneShield is a start-up trying to change that. The company, based in Herndon, Virginia, has developed technology to detect consumer quadcopters and multicopters. It was launched in 2014 by two former defense contractors, John Franklin and Brian Hearing, after they saw an explosion in the use of consumer drones.
