Review on Long Range Wireless Driveway Alarm - 1/2 Mile Detection Range - Weather Resistant Outdoor Motion Sensor and 🔔 Detector - DIY Security Alert System to Monitor and Protect Indoor/Outdoor Property - Includes 1 Receiver and 1 Sensor by Kenny Hrdlicka

We live in a rural area close to town on a long narrow lot. Our living space is on the opposite side of the house from the driveway, so without this alarm we don't know if cars are turning in our 450-foot driveway. We are not crime free having recently stolen a truck so knowing who is driving or on property is more important than ever. Be proactive and get it before you have a problem. I will order another sensor to put where the truck is parked. My ideal setup would be 2 sensors and 2 receivers all working together. I want the receiver to be in the living room and upstairs in my office. Simply remove the waterproof cover from the transmitter, insert 3 AA batteries and in minutes you are ready to be protected. If you are in a hurry, use the rubber band to lift the transmitter. The "owl's eyes" on the receiver light up when triggered, giving you audible and visual alerts. There are several alarm tones to choose from and when I spotted a barking dog I was sold on this device. Tests: Our 450-foot distance is not a test for this device. So far for a week. Today I got in the car to check the distance. While this doesn't work through forests, line of sight or translucency worked at 900ft, 1100ft, and 1700ft (which was as far as I could go before the trees got in the way).
