    Anything that’s capable of detecting drones would get hella false positives from birds/bikes/cars/people. There’s a reason radar usually ignores movement under a certain altitude.

    You could detect via radio signals, but fly-by-wire drones are already a thing, perfect for short distances, like what you’d need to move a package over a wall.

      Birds might be tough, but modern radars/lidars can get smart. I doubt anything terrestrial would be a problem.

      How much border you can cover for a given price and how well is a much different question, though.

      It probably can be done with some combination of signal sources. Yeah radar alone doesn’t sound great. It might be possible combined with computer vision, other computer signal pattern recognition, etc. Whoever gets a decent system like that working would have a lot of sales for it.
