SimpliSafe protects your whole home 24/7 with 3 coordinated layers of protection. First, we work to prevent break-ins at the perimeter. With SimpliSafe® Active Guard Outdoor Protection (available with select plans), smart AI cameras detect motion outside your home, and live U.S.-based agents can help stop intruders before they get inside. If someone does attempt to break in, entry, door, window, and motion sensors detect it immediately, sound the alarm and send you an alert right to your phone. With a professionally monitored plan, agents will then review the event in real time and can request dispatch of police, fire, or emergency medical services, so you get help fast.

Protection doesn't stop at burglary. Smoke, water leak, and extreme temperature sensors detect fire, water damage, and freezes the moment they happen, and the same monitoring team dispatches help fast — so your home is covered around the clock, not just against intruders.

Long-term contracts are not required. SimpliSafe monitoring plans are month-to-month so you're never locked in. And with free shipping, free returns, and a 60-day money-back guarantee, there's no risk in trying it.

Professional monitoring starts at about a dollar a day, with no long-term commitment. And many home insurance providers offer discounts of up to 15% for monitored systems, which may help offset the cost. Check with your insurance provider for eligibility and actual discounts. They may vary by region.

No. SimpliSafe is designed to be set up by anyone — no tools, no drilling, no technician visit needed. Sensors peel and stick right onto doors, windows, and walls, and the app walks you through every step. Customers can be up and running in under an hour. The sensors are compact and built to disappear into your space, so there's nothing bulky to hide. If you'd still prefer a pro to handle it, that option is available too.

Unlike traditional home security systems that alert you only after a break-in occurs, SimpliSafe is built to stop break-ins before they start — both outside and inside your home. Outdoors, live agents can see activity through your cameras and act to deter a threat before anyone reaches the door. If someone does get inside, indoor cameras and live agents can also step in and respond in real time, not just record what happened.

In addition:

ADT professionally installed system plans typically lock you in for 3 years with early termination fees. SimpliSafe is month-to-month, no long-term contracts required.

Ring's newest generation of sensors also offers live-agent deterrence, but relies on Wi-Fi — and even your neighbor's internet connection — to work. SimpliSafe has built-in network backup, so your home stays protected even when power or Wi-Fi go out.

With SimpliSafe, you’ll experience no long-term contracts, no hidden fees, and protection built to get ahead of a break-in — inside and out.

Yes. SimpliSafe includes built-in network backup with your monitoring plan, so if your internet goes down — or someone cuts the line — your system stays armed and your professional monitoring stays active for up to 24 hours. There's no gap in protection. Sensors also run on batteries that last up to 3 to 5 years depending placement, usage and settings, so even a power outage won't take your system offline. Note that cameras require Wi-Fi to stream and record, so video features will be unavailable until your connection is restored. Video recordings and professional monitoring require a paid plan. Network coverage is subject to regional carrier coverage and availability.

With 24/7 professional monitoring, the moment an alarm triggers you're notified instantly through app push notifications and alarm texts — you can cancel or confirm right from there using the app, keypad, or by replying to the text. If you have cameras, monitoring agents can visually verify what's happening before acting, which means they can request priority dispatch for faster police response. If you don't respond, an agent will call you and ask for your Safe Word. No answer, wrong Safe Word, or something seems off — they request dispatch of police, fire, or emergency medical services right away. For plans that include SimpliSafe® Active Guard Outdoor Protection, agents can intervene before a threat even reaches your door. And if you're ever forced to disarm under duress, entering your Duress PIN silently alerts authorities without the intruder knowing.

Yes, and third parties agree. SimpliSafe has been named a top home security system by U.S. News & World Report seven straight years. It’s also been consistently recognized by Newsweek and USA Today for outstanding customer service. 6 million customers rely on SimpliSafe for home security. And with a 60-day money-back guarantee and no long-term contract required, you can try it in your home risk-free.

SimpliSafe has three modes: Home, Away, and Off. Home and Away are both armed states — the difference is which sensors are active. Off disables your burglary sensors entirely. When armed, your monitoring plan ensures agents can request dispatch of emergency services if an alarm triggers.

You can arm or disarm using the app, keypad, or key fob — whichever is most convenient. In the app, just tap Home, Away, or Off. On the keypad, press the corresponding button (disarming requires your PIN). The key fob works the same way with a single button press.

If you have a Smart Lock, entering your PIN to unlock your door will also disarm the system. And if you're ever under duress, entering your Duress PIN disarms quietly while immediately alerting authorities — no confirmation call.
