Title: NOT AS GOOD AS I THOUGHT
Review: I paid nearly a hundred $ for this product for the end of my driveway to alert me when someone pulled in , but the buzzer was not very loud and there is no volume control on it and it only detects up too 30 feet so i can t cover my hole driveway and you have to cross the beam it does not work well if you move directly toward to it it tracks crossway better
