Title: Does not work properly
Review: This alarm seemed like the perfect idea to alert me of cars coming up my driveway. Wrong! First, it did not go off when cars came in my driveway, even after we tested it several times and it worked just fine. Then one day it decided to go off non stop! And there was nothing there! We followed the instructions perfectly so it was not due to user error. This would be a great product if it worked properly. I returned it.
