The latest Mighty Mule driveway alarm is a cost effective way to alert you when vehicles are entering your driveway or property. The in-ground electromagnetic sensor detects vehicles entering and exiting your driveway, and alerts you with a volume selectable indoor chime. It does not detect animals or people. The outdoor sensor communicates wirelessly up to 400 ft. to the internal base station(s). The new Mighty Mule Driveway Alarm is multiple-base station compatible, allowing you to place additional indoor receivers in several rooms of your home, workshop or garage (within range). Sensitivity adjustment ensures accuracy and reduces unwanted alarms. The unit is very easy to install, and requires 2 AA batteries
