Solar Driveway Alarm Wireless Outside Weatherproof (CH-MR2022-Black-1T1)

The instructions were clear and installation easy. My driveway is over 20 feet wide and this device picks up cars on the far side of its installation.

Does not work as advertised, have moved it 3 times, each time closer to the house. Currently about 60 feet from house, works about 10 % of the time

I have been using this product as an alarm on my driveway for just under a year now. Works great for me at about 700 ft from my house. It did start to malfunction recently so I emailed tech support and after some troubleshooting it was determined that the transmitter was malfunctioning. They immediately sent a new transmitter and this resolved my issue.

For the price it works well and does what it says it will do. However, and it’s a big however for me, the receiver and transmitter must be very near line of site for it to work. Also, there can’t be too much in the way that will interfere with the radio waves.In my situation, my house is on up a bit of hill. The transmitter (which is attached to the sensor via a long cable) has to be about three feet off the ground and the receiver high in the window for it to reliably work. This essentially line of sight from one to the other. If the receiver is on a desk near the window it works about 50% of the time, and if I put the transmitter on the supplied pole it almost never works regardless of where the receiver is. Luckily for me, I have lights at the end of my driveway and am able to mount the transmitter higher and still somewhat discreetly. In my situation, the receiver and transmitter are no more than 300 feet apart.The only other comment I’ll add is that the alarm volume can only be set to a few increments. I really haven’t found the sweet spot and have settled for one that’s a bit louder than I’d like.

Liked the range and the solar charging but my solar panel is cloudy so think it quit charging
