Safety alarm question.

Posted by ComplaintOk807@reddit | preppers | View on Reddit | 31 comments

Hi all! So we recently started renting out our basement after I had a baby. (I’m working part time and avoiding daycare by working opposite shift of my husband. We chose to rent out our basement to help supplement my income.)

Anyway, I love our tenant and it’s going great. But she is a single woman and her door comes into the house. My only safety concern is what if she has a guest who ends up being dangerous or tries to rob the house. Do you know of any type of motion sensor device I could put on OUR stairs that could alert me in the middle of the night if someone comes up them?

Would love any suggestions!
