>> it's a nightmare scenario for security services. A militant has strapped a small bomb to a consumer grade drone, the kind anyone can buy on the Internet. They plan to fly it into a crowded sports arena.>> This piece of equipment could hold the key to countering the threat.
I'm Reuters Matthew Laratunda at the Defense and Security Equipment International Expo in London. It's a major weapons conference, where emerging technologies like this are rapidly drawing the attention of security forces worldwide.>> This is called the Night Fighter and it's a counter measure designed by a company called Steel Rock.
Some members of the firm staff are British military veterans who experienced first-hand how Islamic State would use drones like these on battlefields in Iraq. They say this device has the capability to actually take control of a suspect drone.>> Our technology is moving forward very quickly as we find a nice little back door into it, so it is becoming very effective.
For instance, protection of an airfield if they are sending an explosive device across the barrier of the airport. We could actually turn around and identify that drone coming in, turn it around and send it back to them.>> The Night Fighter has been field tested by the British military and the company is pursuing variants for domestic use.
But to stop a drone, you have to see it first or at least hear it, that's where devices like this come in from developer Microflown AVISA. It is a sensitive microphone that can isolate the sound of a drone from background noise, such as air conditioners and pinpoint its location.
It's partly financed by the Dutch Defense Ministry and was deployed to a G7 conference two years ago when it was still in its experimental phase.>> If you would like to seal off a certain parameter, let's say for the Super Bowl in the United States or whatever, you could seal off a parameter let's say by placing these sensors.
Let's say, probably one kilometer outside of this event taking place because you need some response time most likely.>> London Police already respond to several dozen drone incidents a year, mostly benign. But unless they can find the pilot, stopping their flight may come down to tech like this.
