Works 100% just what the doctor ordered

This product works wonderfully. I purchased this for my friend who owns a shop and she needed to know when customers and vendors would come into her shop. I like that I could adjust the sensor downward so only when you walk in/out it is chiming and yet she could walk around her shop without it going off constantly. Everything arrived nicely packed and it was easy installation.

I thought this thing was going to be great, turns out it has really short range where I wanted to use it. I assume its influenced by how much IR light is in the area. Obviously not waterproof either

as advertised. effective alert when someone is on the property

Loud and does it what it does. Still working now after heavy daily use. using it for work purposes.
