I thought it was a foreign company until I saw this:
Anyone know or can estimate a guess on the take off cost for these compared to say, a helicopter traffic police may use ?
I think as technology becomes more easily available we'll see many of these mini choppers or the type that PKK used to fly over the border.
Thus I think it's important to have passive radar relays (where it's necessary) and create a spiderweb that detects and reports these border movements to control center/AI that can switch to cameras that can zoom in on the object.
Not cheap of course and not starting on creating that web isn't going to make it easier when it becomes necessary.
