Installing a DIY Outdoor Motion Sensor System in 30 Minutes
“The Guardline is a premium outdoor DIY motion sensor alert system, but it doesn't need to connect to the internet and share your private info. It's high—tech, but simple and expandable. I had my three sensors mounted and working perfectly in about 30 minutes with the ability to expand to 4 zones with up to 16 sensors at some point if I want. Here's how easy the install went.” READ FULL EXPERT REVIEW
Peace of mind with the Guardline Driveway Alarm
“We've had the system installed for about a week and it has worked great. Our friend stores his trailer in the back next to our tractor. When he came to pick it up the other day l was alerted when he came up the drive. then when he drove beside the building. And finally when he hooked up the trailer. I also knew exactly when he left the property.” READ FULL EXPERT REVIEW
Returning the item. Stopped working properly after 2 days
Like the product
The only problem I have is when the heat goes up the alarm goes off when no one or thing is in the line of the beam other than that I think it is great
every morning its starts going off every 30 seconds with nothing there, wakes us up during the night and went out to look and it continued to go off with nothing there, so I changed it to go off every 30 seconds instead of 5. it works fine with the distance of our 250' driveway, problem with false alarms
