This is the only reliable drive alarm I've ever found that will work from our gate to the house (exactly 600' line of sight). I need to move the sensor above the fence to get it in the clear, when we have wet or drizzly conditions it doesn't work, I suspect the signal gets attenuated too much due to the moisture and fence proximity. I installed it two or three years ago.Just installed 1/4 Mille version of guardline driveway alarm. Works great. It is expandable.

Oh, I've never had a false alarm with this but it looks down and across from our gate entrance.
Oh, (#2) - I tried a Dakota alert and sent it back to Amazon. Wouldn't work at 600'.
