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 from our website.

Purchasing Additional Sensors

To purchase additional sensors for your SimpliSafe® system, first note 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® App using the Shop Sensors tab under the three-bar navigation menu.

NOTE: We no longer offer CO Detectors for the Gen 3 SimpliSafe® System and the Original SimpliSafe® System. If you are having trouble with your CO Detector, please contact our support team for additional assistance.
