Great Security Sensor!!!!
I have installed the 500ft sensor and Love it. I live in the country and needed someway to know when someone was driving up my driveway. This is perfect and gives me a sense of protection and let’s me know when someone is about to knock on my door. So grateful for the excellent service from Guardline Team!!!!!!!!

Excellent product and Customer Support
Mixed results placing them outside around our house, but work well to notify us of motion in the front of our house.
not working
Have tried pairing this receiver 5 or 6 times and it is not working.

frustrating
In a word: frustrating. I have friends who have bought alarm systems for their driveways, take them home plugged them in, wa-la, starts alerting right away. I have on three occasions read the instructions, followed precisely, had someone read and agree to instructions, tried again. Watched YouTube video and still could not get sensor to pair with alarm. Ordered another brand, would like return instructions.

Extra sensor purchase
I purchased an extra sensor and was told that it may not function due to the operating frequency change. I was told that if it would not work then they could replace the entire system. So, I got the new sensor and it would not function. I was sent another sensor being assured that it was the proper frequency. It was not nor would it function. I'd be satisfied if I would receive a controller with two sensors and everything is functional. This is a poor design if the new sensor will not function with the old controller.
