Bests & Worsts Reviews from Amazon

I've been using a $15 Harbor Freight driveway sensor for years... gone through 2 of them. I thought missed detections and false alarms was just to be expected. But this spring when I was getting false alarms several times a day, I got mad and looked to find a better unit. After some study, I selected this Guardline alarm and I'm very glad I did. It was much more expensive that what I had been using, but if it really worked well the additional cost would be worth it to me. I ordered it through Amazon. It arrived just a few days later. There were two boxes inside- one for the alarm portion that goes into the house, the other the sensor that gets mounted outside so it has a view of the driveway. The setup instructions were very clear and easy to follow. The sensor was easy to assemble and insert the AAA batteries needed. Pairing with the receiver went smoothly. In my use, the receiver is inside of a steel sided house and the sensor is about 150 feet away. The sensor is mounted about 4' high, is attached to a pine board which is, in turn, attached to a tree. It is possible to point the sensor in various directions, enable a slow speed detection, alter maximum detection range, change re-detection time, and adjust sensitivity. In fact, I was surprised at how custom this alarm can be. Every thing went real smoothly ..... except I was getting too many false alarms and a few missed detections. I went back to the sensor and tried to readjust where it pointed. That made a tremendous difference in performance. After using it for well over a week, I am delighted with its sensitivity. I get very few false alarms (deer walking past the sensor, a huge crow walking on the driveway, and a few alarms with unknown causes) but every true situation (car in driveway, person walking in driveway) has been picked up. Perhaps the most difficult part of the system configuration is deciding which of the 32 alarm sounds you want to hear.... I chose a "car horn" and that has been working well. I have also been contacted by the company, twice, asking if the setup was going ok or if I could use any help (I never needed their help). Bottom line: high quality product, rapid delivery, good instructions to setup, ample offers of assistance if needed, and excellent performance. That was actually more than I was expecting from this driveway alert product. Was it worth a more premium price? Absolutely yes. I have no regrets at all about this purchase.
