Review on Long Range Wireless Driveway Alarm - 1/2 Mile Detection Range - Weather Resistant Outdoor Motion Sensor and 🔔 Detector - DIY Security Alert System to Monitor and Protect Indoor/Outdoor Property - Includes 1 Receiver and 1 Sensor by John Larsen

We have a HTZSAFE driveway alarm that works great. While it's obvious that this is a sensor, since we have it in the tree no one seems to notice. Your customer service is the best! The sensor wasn't working properly so I contacted them to see if I set it up properly. A new one arrived two days later. No questions asked, no returns. I had no more problems. I wanted one for our farther front gate and when the company offered it for me to test I thought it would be perfect. It doesn't look like a sensor, which I really like. It was extensively tested this weekend. We had wind, rain, sub-zero temperatures and lots of traffic jams. Unless it is half a mile away, there will be trees and bushes between the sensor and the receiver. There doesn't seem to be any problem with that. I also like that you can change the range. I set it to a shorter range so it doesn't catch deer and other wildlife crossing the road. It has 35 different alarm tones and volume control. The only thing I can't rate are the batteries. As we've only had them for a week I don't know how long they will last. We have another solar system so we never have to worry about it. Maybe they release the sun and other cute animals. Although I got this for free, believe me I wouldn't hesitate to give a bad review if I couldn't recommend it.
