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.

Frequency Change

I wanted a second receiver to go with my driveway sensor. When I continually had problems pairing my new receiver, which is very simple,I called Guardline and was told that a frequency change has been made and I will have to buy a new sensor receiver combination to go with my new receiver. A good product. Unhappy with the change and how I found out.
