Absolutely. There are two Entry Sensors included in your do-it-yourself security system, which can be used to protect two doors or windows. The Motion Sensor can be used to fill in coverage in a room with lots of windows. Plus, SimpliSafe was designed to be expandable - you can easily order extra Entry Sensors along with your system if there are additional windows that you’d like to protect. According to the National Burglar and Fire Alarm Association, almost 80% of all home invasions occur through the front door, back door or a first floor window.

The additional DIY Security System components that you can order are: Keychain Remote, Motion Sensor, Entry Sensor or Panic Button. Additional Keypads will be available in the future. Up to 20 additional components can be added to your system, for a total of 26 components (note: the Base Station and additional Sirens are not considered a component).

We recommend that you place your DIY Security System's Entry Sensors on all doors and windows that could be accessible to an intruder. If you live on an upper floor, this likely includes your front door and a fire escape in the back. If you live on the ground floor, you can use the Motion Sensor to fill-in coverage in a room with lots of windows. You may also want to consider purchasing additional sensors for extra protection.
