I have a DS-2CD4A26FWD-IZHS from Hikvision. Quite old, but works well. But lately it has started to annoy me a lot that I get so many "hits" on sheep behind a fence that goes diagonally across the picture. Even if the sheep are meters behind the fence and the camera setup (squares and lines) is on "my" side of the fence, I get mail on both Intrusion and line crossing. It is probably not possible to do anything about this on this camera, but is the same problem on newer cameras?
