Hardy driveway alarm. Rather simple with only double beep. Do like the top shield, which protects the sun. Had one before this is a replacement but works like a charm. You'll know when someones here. Only issue is if there are lots of cats or other animals but thats what videos feeds are for.

Not sure why this product is so bad. My first one lasted about 3-months until is kept alarming non-stop. I replaced it with another identical unit that I thought was fine. It was beeping during the install and mounting process. Problem is the range is only about 5 feet. I double checked my distance and sensitivity settings and they were correct at the 30' distance and more sensitive setting. Pure junk. Read the other 'real' reviews.

I have been using these for 3 years now with good results. My driveway is over 300 feet long and I have a lot of trees on the property. These sensors (I have 4 of them) work well and let me know when and where someone is on my driveway and parking area. The battery life is sometimes a little short in the cold winter time, but otherwise I am pleased.

Have used this brand of sensor for years. Previous one worked great until a truck crashed into it
