Dakota Alert 4000 Wireless Receiver & Chime Kit - Long Range Security Alarm System for Home, Garage, and Business Protection

Installed the Dakota Alert 4000 Wireless Driveway Probe Alarm System July 2019 because we live on a 40 acre parcel with a long out of sight driveway entrance to front and backyard.Transmitter probe is set about 20' up the driveway from the main road on one side at a depth of about 10". Driveway is about 14' wide.Now we get ample warning for house and backyard traffic.Placed a receiver outside at my tool shed under the eaves in the backyard (500'+ over hills, house and trees from transmitter) and one in the house. The tool shed receiver is still going strong but house one failed so ordered this as a replacement (Expensive but felt naked without it).Our transmitter is approximately 300' from the house (over a hill, through trees and into house). Used a vehicle with an AC outlet to set up the new receiver. Works great if you have a person in the vehicle.Needing AC to set up the receiver is the only drawback of this system for us. First set up for house and tool shed was with my tractor and an inverter.We felt unsecure when the house receiver failed and surprised the house one (indoors) failed before the tool shed one did.The transmitter has replaceable batteries. It has seen -38C (-36.4F) temps since 2019 and still worked and have not needed to change the batteries, yet...knock on wood.There is a sensitivity setting on the transmitter. Lightning will set it off if set too high. It took a short time for me to get it tuned to our needs.Would I buy this system again or suggest to others?...Absolutely!
