Review on 🔔 Wireless Driveway Alarm System - 1byone Motion Sensor Alarm with Extra Loud Chimes, 1000 FT Range, 1 Receiver, 2 Weatherproof Infrared Sensors - Ultimate Home Security for Indoor/Outdoor Property Protection by Agustin Bush

Works great. The battery lasts a long time. Usually he rings three times; but when the motion sensor battery is low, it will ring once. And that's great because it lets you know it needs to change. Really easy to install; Just insert the screw into the wall and hook it. Large distance to sensors. The shaft extends 20 meters to the street. And I catch all cars, postmen and couriers. My tailgate sensor actually works through 3mm slots in my fence. This is how he catches anyone who comes by in an ally. I have cameras, but the robbers hide their faces. Sound works much better. Since my front fence is only three feet high, people sometimes jump over the fence. But now the sound works because the robbers hear it and don't think about jumping over the fence because it's a harder target. Also, my neighborhood dogs will hear it and bark at night. He also catches animals. lol The perfect product. It's better to be offensive and deter crime than surveillance cameras that criminals don't see or care about.
