DJI Phantom

But yeah, that's what sucks with this whole FCC ban is a lot of our clients are in critical infrastructure, cannot fly DJI.

And you know, having these pilots fly a Phantom around an obstacle course, you don't really care if they dump the Phantom, right?

Right.

Yeah, right.

Although-

... a Skydio-

Although the Phantom, Phantom 4 Pro is my favorite drone of all time.

[laughs] I'm not, I'm not arguing that one bit.

The BPF is the dominant and distinctive frequency.

A typical quadcopter, DJI Phantom four, with two blade propellers and RPM approximately equals eight thousand to ten thousand produces a BPF approximately equals two hundred and sixty-seven to three hundred and thirty-three hertz.

Models with different configurations, hex, octo, multiple blades have distinct identifiable spectral fingerprints.

Four, five.

twenty seventeen four demonstrated that a deep neural network trained on mel spectrograms of drone sounds can detect the presence of a drone with greater than ninety-five percent accuracy at distances of up to eighty meters in semi-controlled environments.

Al-Hamadi et al.

twenty nineteen five extended the approach to identifying the specific model, DJI Phantom versus Parrot Bebop versus background using MFCC and CNN, obtaining ninety-eight percent accuracy on the test set.

The parallel with speaker identification is direct.

Future Warfare is going to incorporate drones.

I think on an individual warfighter basis, it's not going to have a whole lot of the DJI Phantom that drops a hand grenade on an enemy position or down into a tanker.

I don't know how much of that there's going to be.

But you can't tell me that like that drones in the near future battle space by individual soldiers are not going to be used to do surveillance or counter surveillance.

Now, hopefully nothing happens to where you're going to have to be aware of it.

But if something were to happen right now, within six months, a lot of dudes would get smoked because they didn't realize the DJI Phantom is just looking at them.

And they're just completely oblivious to it.

If, like, I don't know, Civil War 2 were to pop off and dudes, plate carriers, were actively out and maneuvering in the urban environments or out in the nature, I think a whole bunch of them would get smoked because of drones.

So aerial photography was the first big market.

I think their first big platform was the Phantom.

a DJI Phantom.

And they really focused not on how cool the device was, but really on what it could do for a consumer.

And they just found themselves in this incredible position with a massive growth market.

And they've continued to keep that ethos of thinking about the consumer, whether that's a business customer or leisure.

That's really been the heart, I think, of their success.

When did they do that then? When was this? 2013, 2014, I think was when the Phantom platform was released.
