Qolsys Wireless Tilt Sensor:

You know that sinking feeling when you return home and see your garage door open? As an easy entrance into your home, you keep a lot of valuable things in your garage. There might more value in the garage than the rest of the house combined. From cars to tools, sports equipment to freezers full of food. Now, you can know when it’s open with the Qolsys Wireless Tilt Sensor, an innovative device that tells your panel whether it’s open or closed.

And since your panel is connected to your alarm account, you’ll be able to see the current status of your garage door at any time from your mobile device or computer.
