I have one of the above-ground Dakota alert sensors that can transmit 200 yards to the house.. It's aimed about 4' above the driveway and is about 20' back. It catches UPS, Fedex, and most cars all the time, but the dark Amazon vans at night it only catches as they leave, and sometimes light colored cars during the day slip by. I'll be looking at adding one of the magnetic sensors to try and improve that accuracy.
It catches me walking by to get the mail, and occasionally things early in the morning (hopefully of the four-legged variety).
I also have the Dakota receiver tied into a Z
