Northern Tool has Chamberlain and Mighty Mule driveway alarm systems.
Chamberlain Wireless Motion Alert System, Model# CWA2000 | Motion Detection | Northern Tool + Equipment
Mighty Mule Wireless Driveway Alarm, Model FM231 | Motion Detection | Northern Tool + Equipment
Do either one of these work worth a darn? Are there other brands worth considering?
Or is this another good idea gone bad due to Chinese manufacturing?
