Protects your doors and windows. Works with most doors or windows.
Pro tip: Stop burglars where they break in most. Ground floor doors and windows. For rooms with 3 or more windows, consider a Motion Sensor instead.
Our most accurate Motion Sensor yet is engineered to tell the difference between people and pets. It protects an entire room from a single location with a 90º field of view and 35 ft. range.
Pro Tip: Place in a corner, 6 feet above the floor for maximum room coverage.
Detects leaks and potential floods, so you can stop water damage before it happens.
Pro tip: Place it close to common household water sources. Your sinks, toilets and water heaters.
Triggers when a fire's still smoldering—before a full fire breaks out. Loud system-wide sirens jolt you awake and out of the house.
Pro tip: Get one for your sleeping areas. Place one in every bedroom for more security.
If you're at home during an intrusion, press this to trigger your alarm and alert our monitoring center.
Pro tip: Place one in your master bedroom for easy access.
An extra keypad for garage door entrances, back doors or upper levels of your home. No power needed.
Pro tip: Don’t buy this now. Your SimpliSafe comes with one already. If you want more later, it’s easy to add them.
Triggers if your home drops below 41°F, so you can stop pipes from freezing and bursting.
Pro tip: Place it near your thermostat in holiday homes and climate-controlled rooms.
About as loud as a Led Zeppelin concert in ’72. Place it inside or outside the house.
Pro tip: Get one. It’ll scare the pants off burglars and alert neighbors to a break-in.
Works just like your car’s key fob. Press a button and your system’s disarmed before you enter your house.
Pro tip: Consider getting one for anyone who might forget their PIN code.

Built for the unexpected
Real home security prepares for the worst. So we built backups. And backups for those backups.
An intruder can damage the keypad. Doesn't matter. We still alert the police. Sorry, bad guys.
Built-in WiFi. Built-in cellular too. One connection down? The other’s still up. That means your home is always secure.
Detects intruders, not pets.
Alarms that cry wolf? No thanks. We precision-engineered our motion sensors to detect the unique heat signature of humans. Not pets.
