The Original SimpliSafe® is a powerful home security system that will keep your home protected.

SimpliSafe offers a variety of components to secure your home including Entry Sensors, Motion Sensors, Glassbreak Sensors, Smoke Detectors, Carbon Monoxide Detectors*, Water Sensors**, Temperature/Freeze Sensors, Panic Buttons, Keychain Remotes, and Auxiliary Sirens. All components are equipped with adhesive strips for installation, as well as screws in case you want them to be more secure. You can have up to 41 sensors synchronized to your Original SimpliSafe® system, and in ideal conditions, they can send signals up to 400 feet away from the Base Station. 

The Original SimpliSafe® system has a cellular connection to our monitoring center, and 24-hour backup batteries to ensure that you’re always protected, even if thieves cut the power. If you’re having trouble with your cellular connection or Base Station, you can view our list of troubleshooting topics in the menu bar or by clicking here.

Users can change their system and device settings through their Keypad’s menu. Fast Protect™ Monitoring Plan users (formerly Interactive Monitoring) can also control their system through the SimpliSafe® mobile app.

If you have already purchased the Original SimpliSafe® please refer to this page for help installing your system. Once installed, you can use your Keypad to test your system. After your system has completed test mode, you will be able to subscribe your system to professional monitoring.

We strongly recommend that you subscribe your security system to professional monitoring. SimpliSafe® has six monitoring centers around the nation to guarantee customers built-in redundancy in the event of a natural disaster. These monitoring centers are open 24 hours a day 365 days a year, so you can be confident whether you are at work or going to sleep that your home is protected. You can be notified immediately via email or text message as well with push notifications, if you are enrolled in our interactive professional monitoring.
