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!!!!!!!!
Mixed results placing them outside around our house, but work well to notify us of motion in the front of our house.
My buying experience was excellent. Customer service is great. I am very pleased with them. I will buy from them in the future.
During a very humid morning the sensor would not shut off it just kept going off and on and off and off I finally had to take the batteries out in about a week later after dried out it was fine again
We have purchased several Guardline systems for ourselves and other family members through the years. Our latest Guardline purchase was for our lake house. We have both the 1/4 mile system and the regular system at our home and have used them without issue for several years. I can honestly say from experience that Guardline makes a great product.
