I can't complain too much. After I called them and let them know what happened they were out the next day, spliced the wires back together and even planted grass seed where they dug up the yard.
You've got alot of options. I called Absolute Automation Driveway Alarm,Vehicle Detectors,Freeze Alarms - and they helped me out a lot. It really depends on what you want to pick up, and what you want to happen when the alarm goes off. You can check out their driveway sensors and also the different types of driveway alarms.
