NPR wants to know

Hi! Was super excited to find this community! I was looking through a post on safety tips, and someone commented that they have a Birdie-type device that will go off if their tent zipper is opened. I would really like something like this, but when I go to the Birdie website, they just have something that attaches to doors with a Command strip. You attach it to each side of the door, and if someone opens it and separates the two parts of the device by more than half an inch, the alarm goes off. I'm not sure how I would attach this to the zippers of my tent. Does anyone know how to use this device in a tent, or know of a similar device that would go off if someone starts to unzip my tent?

Thank you!!!
