testimonials

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
