Review on 🚨 1byone Driveway Alarm: Motion Sensor 1000ft Range, 36 Melodies, Home Security System with 1 Receiver & 2 Weatherproof Detectors - Protect Indoor/Outdoor Property by Mike Swanson

This motion detector is great and you can adjust its volume as needed. I have several of these installed on my website. This is my second set that I have bought. I have a sensor at the end of my driveway so I know when someone is moving in. Another stands behind my chicken coop to warn me if anything is coming. I have another by our blueberry garden and one outside the vegetable garden next to the bird feeders. We had problems with a bear coming in to destroy my feeders. At least I'll be notified when something comes up. They are very sensitive and I love that you can set a different alarm sound for each one to see which one worked.
