How does it work?
If you go to the official website then you may not find where it says how it works, but according to rt.com it is a "jammer that bamboozles drones through pulses of radio waves at frequencies between 2.38 and 5.82Ghz.".
It can cover up 2km in a wide range of environmental conditions.
Are you allowed to have this?
It seems like if are in the USA then you may not be able to buy it at the moment, that's what it says. "This device is not, and may not be, offered for sale or lease, or sold or leased, in the United States, other than to the United States government and its agencies, until such authorization is obtained."
Let's see what other people thinking about this DroneGun.
*[Also this is pointless since drones can be programmed to return to its launch location when it loses signal.]*
He is probably talking about the drone which comes to its original place when it loses signal from the remote by using GPS. But because GPS can also be spoofed, so his argument may not be valid.
*[This is the finest bullshit I've ever seen so far... You can't just hook into a secured and encrypted connection between a DJI remote and drone like that, max. you can do is to cut the connection between the drone and the pilots remote tho then the drone will simply hover 2 minutes in the air and return to home after that, but NOT LAND IN FRONT OF THE DRONEGUN USER!]*
This comment sounds good but what if the gun can record the frequencies of the encrypted data from the remote then sends it to the drone? Remember drone can generate frequencies between 2.38 and 5.82Ghz.
If you read the comments under the video on YouTube, you will find many people are still skeptical about this device. Some of them are saying that it maybe a fake video.
