Review on 🏡 Enhance Home Security with a Weatherproof Driveway Alarm: Long Range Wireless Motion Sensor for DIY Safety System - Ideal for Yard, Garage, Gate, and Pool Safety by Tony Suggs

How do you put together this motion sensor and sell it for so cheap? I use mine to practice on the bottom of a bird feeder to see what animal is trying to get there. I've found that sometimes it works on a bird (bigger type like cardinal or catbird) flying close to the detector. And sometimes it's triggered by a chipmunk as it passes the detector. They are sporadic and unpredictable. Some would call them false alarms. I would not. Every detector is subject to such things. All in all I would buy this again. And if I had another application to find out if someone is driving on my road, for example, I would use it for that too.
