Review on 🚨 Guardline Wireless Driveway Alarm Extra Receiver - Extend Range up to 500 ft. by George Kapoor

I am in no way affiliated with this company and this unit was excellent. And I've had them for about a year now. The sensor is at the top of the lane about 50-75 meters from the house and shop where I have 2 receivers. The sensor is approximately 2 to 3 feet above the road surface, tilted slightly downward and at an angle of approximately 20º to the direction of the road. There are 2 walls between the sensor and each receiver. Our home is in PNW where, in case you haven't heard, it's raining. And the sun. And where we live, snow and strong winds. Installation and configuration took about 15 minutes and then another 5-10 minutes for fine tuning. With the exception of changing the battery in the 1x sensor, I never had to touch the system again. Works great. It's nice to be able to choose your own alarm clock and adjust the volume loud enough to be heard anywhere in the house (even outside in the yard). We rarely get false alarms about wind. Both dogs and deer will sound the alarm. Couldn't be happier.
