1/2 Mile Long Range Solar Wireless Driveway Alarm System IP65 Weatherproof Outdoor Motion Detectors&Sensor 120dB Siren Sound Light Security Alert System Monitor&Protect Outdoor/Indoor Property(1R4S)

The alarm system came pre-configured. There was nothing to set up or connect. Just turn on the receiver and sensors and it works great. I love that it is solar and USB so there are no batteries to ever go dead or replace. I have the sensors positioned on an off-grid property and they work fantastic. I haven't tested their full range to see if it's 1/2 mile as advertised, but I can say from experience they work well at around 1/8 mile with clear line of sight. There have been no false alarms even with the sensitivity turned all the way up. If you don't want small animals to trigger the alarm, mount the sensors higher and tilt them more up off the ground. The alarm sound and lights annoy the heck out of the coyotes who have since sought other, more tranquil accommodations elsewhere. You can also configure the sensors to lights only, alarm sound only or silent alarm with base station ring only.

Had another brand first that could only bash the little owl's. Received them and they would not work out of the box. Purchased the owl's and Love them. Easy to set up and get things going. Work great. Longest from house about 300 yards and it work everytime. Will buy again if need comes up.

Loved the option of the flashing lights and alarm on the individual sensors. I got 4 sensors and they paired easily with the base. I would definitely recommend this product. Arrived as promised and packaged well.

Hope they last.

Very good product, would buy again
