Your SimpliSafe® System will come with a Yard Sign, Window Decals, and plenty of adhesive tape to secure your sensors. These items can go a long way in deterring potential intruders from your home.

The following article will guide you through purchasing additional sensors, yard signs, and window decals.

Purchasing Additional Sensors

To purchase additional sensors for your SimpliSafe® system, first take note of which version of SimpliSafe® you have. Once you have determined if you are using the Original SimpliSafe® system, or a Gen 3 SimpliSafe® system, you can navigate to our online store to purchase additional sensors. When on that page, simply click into your system type and then add the products you wish to purchase to your cart.

If you are subscribed to Pro Plus, Pro, or Core, you are eligible to receive a 10% discount on your order for additional sensors and products. These orders must be placed within the SimpliSafe® Mobile App using the Shop Sensors tab under the three-bar navigation menu.

NOTE: We no longer offer CO Detectors for the Original SimpliSafe® system. If you are having trouble with your Original SimpliSafe® CO Detector, please contact our support team to learn more about upgrading your system.

Purchasing Yard Signs and Window Decals

Our Yard Signs are 9 inches by 11 inches and come with a stake for easy display.

Our Window Decals are 3 inches by 3 inches and come in a pack of two (2). They are a great way to create an extra deterrent on your window, or other entry points.

To purchase yard signs or window decals, navigate to our online store. Then, select Gen 3 SimpliSafe® (even if you do not have a Gen 3 System). Scroll to the bottom of the screen, where you’ll find these two products listed. Then add the yard sign and/or window decals to your cart.
