Title: False Alarm
Review: After reading all the other reviews I felt confident purchasing this item. After placing it on a post at the end of our drive I quickly found out it was too far from the receiver. I moved it about 60 ft closer on a tree at the bend of the drive. Still it wouldn't pick up anything, finally I moved the receiver into the front bedroom in the window sill. That put the two components about 50 ft apart. Then it picked up almost everything including the wind but several times it didn't "see" cars that came into the driveway. My husband travels for business and is gone a lot, we live way out in the woods and our house faces the lake with the back facing the road, we have no neighbors and I thought this would be great to warn me when the rare visitor comes to call. You get what you pay for and even less with this thing.
