Review on Driveway Alarm Wireless Motion Detector Alarm 600 Feet Long Range Outdoor Weather Resistant Motion Sensor & Detector Security Alert System Monitor Protect Outside/Inside Property by Joe Taniguchi

Had to move it and turn it more towards the driveway as large vehicles (trucks) would trigger it. Would detect vehicle in driveway 85% of the time, would randomly trigger on nothing the other 15%. Worse thing is it would emit "roaring growl" like a Jurassic Park movie dinosaur at random times with nothing in drive or on highway. Called tech support, they said to take batteries out and reset and set it up again from scratch. I did this 3 times, set a different alarm tone each time, which worked but the random "roaring growl" never went away and the 15% random phantom trigger continued. Sending it back.
