Pretty much. They are only worried that people near the crossing will actually see illegal border crossers. Just move ‘em a bit outta view...
Also, build a couple of towers about 150 meters to each side and place one person up there watching with a rifle. About every two hours or so fire off one round while appearing to aim at something. Blanks may be useful here. Just want to scare someone that tries to do an end run around such a short fence.
