    Had to buy more ( 6 ) sensors to protect the windows. The ( 4 ) sensors that came with the Ring Alarm system were used to protect the doors. Easy to install , compact and they will work when offset from each other or turned sideways. Had to be creative for two of the doors..... kitchen door to garage and the sliding glass door. ( see enclosed pics ) So far everything has been working great and no false alarms.

    We started with the security system and added these door sensors to our system at home. They were simple to install and add to our Ring App security system. We have every door protected and they have worked great since day 1. If you are looking for a great way to protect your home and install it yourself I highly recommend these comtact sensors.

    My ring alarm system didn't work well at all. several of the sensors weren't placed during the original installation. Anyone could've gotten in and out of my house without me and my spouse knowing. I had motion sensors but not enough sensors to cover my doors . These are a game changer .
