I bought these alarms for several purposes. One to be alerted if a window was being opened and the others for doors. I use them in inside doors to know when my kids get up and open their doors because I didn't always hear them before I installed the alarms.These work perfectly for that. They are very easy to install and have four alarms to choose from. All I had to do was move the switch one or more times to choose each one. The alarms are loud and startling but exactly what I needed. They blend in with my white trimmed windows.
