Amazing Product and Really Amazing Customer Service

I have used cheap driveway alerts for years - constantly being upset with their performance and chewing through batteries. After the last one failed, I decided to try Guardline's sensor. A bit more expensive, yes, but after being frustrated with $20 sensors in the past, I wanted to give it a try. I am amazed with both customer service and sensor quality! I wish I would have switched to Guardline years ago. I have their sensor mounted on a tree about 30' from the mouth of our driveway where it is sheltered. It was easy to setup and put into operation. Detection accuracy was great for a few weeks but then it had an error of constantly alerting. I called Guardline Customer Service and spoke with a most knowledgeable person. We tried a few solutions which didn't resolve the issue so he said he would send me a brand new sensor.....which arrived a few days after our phone call. The replacement sensor is working perfectly. It is about 150' from the sensor to the interior room in my steel-sided house where the receiver is located. Good strong signal as every detection comes though fine. I have the driveway under video surveillance and can glance at a monitor whenever the Guardline alerts: mailman, paper boy, cars in the driveway, UPS/FEDEX delivery vans, even people walking in the driveway have been 100% detected. False alarms are exceedingly rare: a large raven and several deer have set it off. But, sunshine, clouds creating shadows, wind blowing tree leaves, and rain do NOT cause false alarms. This is after about 2 months of experience. The system can support multiple sensors. I may get additional ones in the future, but what I have is really meeting my needs. Very good quality and superb customer service. I am very pleased!

Doesn’t Work Well at All

I purchased this product based on a friend’s experience. The first sensor was defective and Guardline had to send me a replacement but I didn’t get a shipping label so had to pay the freight for the return. No reimbursement so far. The second sensor seemed to be O.K. and I set it up with the sensor approximately 150’ away from the receiver. I figured, since this was a 500’ unit, that would be fine. Not. It didn’t work. Worse, it tripped the receiver when nothing was present. I moved the sensor closer to the receiver and it kept going off at odd intervals with nothing between it and the receiver. I disconnected the unit and will probably throw it away. I wouldn’t recommend this device to anyone. I had high hopes that it would work, but it doesn’t. Sure, it goes off. But there was no activity that would make it do so.

The sensor does not pick

The sensor does not pick up most of the time. They replaced the first one but it hasn't made a difference.
