Hi and welcome to the Nikon DSLR forum.
As Eric said, this isn't our speciality but I can say having had a quick look at your links that this is typical of micro cameras used in these flying devices (drones?).
In order to get a wider angle with such small sensors, inevitably compromise has to be made between cost, quality and lightness. The result is loads of distortion.
At this scale the distortion is pretty well unavoidable. If it's a huge issue then it can be corrected using Adobe Lightroom or other software. I believe that can also apply to video recordings too, although in both cases it means losing some of the image.
The Phantom 4 has a 1", 20mp sensor, Robert. Very impressive IQ.
I don't know what focal length its lens is, but given that you have to fly at above 30m having a wide angle could be a handicap...so I 'think' they may be longer than you would expect. But don't quote me.
I recall doing a fix point rotation around a rugby H from 30m and it occupied almost 1/3 of the frame.
