It took a few tries to align properly but works great. Highly recommend.
We live off the highway 600 yards. This is the trick for knowing when someone comes up the driveway. Has worked great from the moment I set it up. Price was well worth the cost of the unit.
This product is performing as described. We have the receivers inside a metal building and there doesn’t appear to be any problem with getting the signal from the sensor mounted on the drive.
I have an 11 acre parcel with the house at one side of the property and entry gate at the other. There is also a creek and hill between the gate and house yet the sensory work perfectly.
