Chtoocy Solar Driveway Alarm Wireless Outside 1/2 Mile Long Range, 3 Sensitivity & Weatherproof for Outdoor/Indoor Property Security Alarm, Rechargeable Battery Expandable Motion Detector & Sensor

I purchased this product after a review of other similar driveway alert systems. I installed and it worked as advertised. I had questions and each time the company responded in a timely manor. They were very helpful. I wanted to upgrade and they are willing to accommodate my needs. We will see how it goes?

Works great! It does have further reach if no obstructions like trees.

One sensor works as advertised. The other sensor works intermittently.The system is great when working. I would love to be able to replace the non-working sensor. Option does not seem available. I would give 5 stars if it worked consistently.

I changed my rating back to 4 because as I started using the product I was getting numerous false alarms. it has become very annoying and the only thing I can do is turn it off. By doing so, I makes the units useless. However, I removed some swaying bushes/branches and reset the sensitivity to mid and it seems to be working fine now.There only 3 reasons for the false alarms. 1) the units are defective 2) birds or spiders 3) wind causing tree or plant branches to sway causing the alarm to go off. I originally thought that the sensor can distinguish human movement from birds or branches. If the problem is 3, then obviously it does not and can not be placed where there maybe wind movement of flowers or trees.

I would be lost without my driveway alarm. It works so well. I’m never surprised by the doorbell, it always tell me when someone is coming in the driveway. I’m handy capped, so it takes me awhile to get to the front door. With this alarm I can look out the windows and see if it’s someone I can let into the house. In fact, it lets me know when the neighbor cat makes a visit, or even when the wind is blowing hard.

Junk. Same tone for all sensors. Very minor brush sets it off. Almost no range .range not as advertised. Going in trash Will buy Hosmart again has worked great for years

Works as stated. Note you cannot match a tone to a specific transmitter. Great for motion detection.

We are talking about flat ground, no obstacles in between. Not even a 10th of a mile, and nothing until I drive over and set it off myself with the receiver in my car. I was using it for perimeter protection for a construction site.*** UPDATE** They reached out to me, replaced the order, the new sensors and receiver works beautifully. Customer service was awesome. I will look for this company to buy from again. VERY pleased!
