800 Meters Solar Driveway Alarm System-Up to 70FT Wide Sensor Range 3 Adjustable Sensitivities-Fully Weatherproof Outdoor Motion Sensor&Detector DIY Security Alert System-1 Receiver and 2 Sensors KIT

Great product. The receiver is probably 100m from the sensor and still works really well to alert us to cars or people on the driveway. Fully adjustable angle/height/sensitivity means we can avoid catching the dog every time she runs past too

Easy set up, and it works. Not tried it at 800 mtrs but it works fine at 300.good bit of kit

This alarm stopped working within 8 months and there as usual I'm finding it difficult if not impossible to contact seller.And as is always the case amozon wash their hands of any responsibility!!! Ps the seller could not have been more helpful and replaced the faulty item swiftly. I now feel ashamed of my review .I was more frustrated with Amazon.

I have installed these sensors, 1 has failed due to water ingress. They are sold as waterproof , which they are obviously not.

Well made and works well. I use it to warn me when wild goats come into the garden and every time I get the warning. The solar is great as I don't need batteries. I will definitely buy another one.

We use this item to create overlapping fields of monitoring around our rural house. It works at very long range, alerting us to visitors on multiple approaches to the house. It does not seem to respond to deer, and thus distinguishes for arriving vehicles or visitors on foot. Be advised the alert monitor is quite loud, so emplace in your house appropriately!

Worked fine for a week or so, then randomly started going off when clearly nothing there, checked for spiders etc none there.Its outside our gate to let know when someone pulls up, but doesn’t always pick up cars that are right in front of it, then it’s going off in the night for no reason had to turn it off in the endIt’s good because it’s solar and don’t have to change batteries but the cheaper one I had last time worked better until water got in battery compartment.

Stopped working after 5 months it was great up to a point when it stopped working when motion was detectedBut it would alarm just out of the blue when no motion detectedTried to find details on Amazon to explain can’t find any information to ask for repair or replacement
