Bests & Worsts Reviews from Amazon

I live in the mountains and there are a lot of bears in the area, these motion detectors literally keep me safe! they warn me when there are bears on my property and where they are! I have 3 detectors and cover all my 1 acre property, they have excellent range and sensitivity, will pick up flying bugs at 2ft. and bears and elk at 150ft! size determines detection distance. my detectors are backed up by video camera's so I can monitor what's going on, the detectors are solar powered with good battery life, the receiver has battery backup which is a good feature if you have a power outage. so I would highly recommend these to anyone who needs a good detection system!
