🚨 Guardline Wireless Driveway Alarm: Motion Detector & Receiver Set - 500 Ft Range, Outdoor Home Security Alert System Review

I've been using Guardline for 3 months now and my initial praise has completely changed. About 6 weeks later the false positives started. I followed the online advice first and then contacted Guardline about a return. "Dave" from Guardline emailed me with a list of suggestions for me to try and if they didn't work he said Guardline would exchange my unit and if it didn't work they would refund my money . I carefully followed his suggestions to remove the gate block, remove its cover, take out…

Installed my system about 8 months ago. Bulletproof. No false alarms. There is no missed movement. Two sensors are located approximately 40 feet from the receiver. After 8 months I checked the batteries in a sensor. The voltage drop was about 0.160 volts. Impressive. It's easy to connect any type of light/sound as it has DC contacts that can be connected to a relay which can then control whatever you want. UPDATE: It's been almost 2 years since I installed my 2 motion sensors and receivers. One

I installed it about 200 feet from home and it reliably detects vehicles or people moving in any direction. I've only had one instance where it appeared to be caused by an (unidentified) animal. To my surprise, it also constantly recognized the electric car. Although the headlights and taillights are LED, they can get hot enough to trigger the sensor, or it can detect heat from the battery. warning sound. Mounting the sensor from the outside was easy, but instead of using the included screws…

I've used a $15 Harbor Freight road sensor for years. 2 passed. I figured the missed detections and false positives were to be expected. But this spring, having false alarms multiple times a day, I got angry and started looking for a better device. After some research I decided to get this Guardline alarm and am very glad I did. It was a lot more expensive than what I was using, but if it worked really well it would have been worth the extra cost. Ordered from Revain. It arrived in just a few…

I usually only review a product that really impresses me or really disappoints me. Unfortunately, this falls into the latter category. We all want to support American companies, but we expect a great product. I had the last traffic light in seven years. It was a solid system from a New Hampshire company, but I decided it was time to try a new technology. I liked the features of Guardline.zone identification, various alarms (more on that later), range and system expansion. As long as the sensors

Update September 2018, 1 year later: It's standing in bad weather and everything worked great for a year of use on our road; very cold winters and very hot summers. I recently changed the batteries, but I did it as a precaution, not because the batteries were dead. We move in and out at least 4-5 times a day, the kids ride our bikes several times a week, plus a few trips to the mailbox. The only thing to watch out for is that when changing the battery the little screws will fall out if you're…
