Review on Wireless Driveway Alarm System - Long Range 1/2 Mile with Solar Power & Weatherproof Design - Adjustable Sensitivities and Outdoor Motion Sensor for DIY Security Alert by Elton Luo

We bought this to replace a cheaper one from the spot that rhymes with "Barber Great". So far this has worked great. Installation was easy and worked very well with almost zero false alarms (unlike the old device). If there's a fire, there's definitely something in the driveway, maybe even one of our dogs or cats. I have it at the shortest minimum range, but it still catches small critters. The sensitivity setting can be nice, but seriously, if an alarm goes off because one of our dogs or cats is down there, it reassures us the device is still working and lets me look through our security cameras to see if anything exactly our attracted dogs to us. property perimeter. What I really like the most is the lack of spare batteries. Our old device had batteries in the sensor and receiver/alarm unit. It has a solar-powered sensor (which you can still charge via a USB port if you can't get enough sunlight) and the receiver plugs into a household outlet. There are also volume controls and options to change the sound of the alarm. It's also been raining heavily for the past two weeks, and it doesn't seem to change the phase of sensory block by one iota.
