Wireless Sensors

SimpliSafe protects you and your space with six easily installed components.

SimpliSafe Base Station

Our Base Station is the brains of your security system. It regularly checks the status of your wireless sensors and uses its cellular unit to call our Emergency Dispatch Center in the event of an alarm.

Wireless Range

All SimpliSafe components are battery-powered and communicate wirelessly with the Base Station, with a 400-500 foot range.

Wireless Keypad

Best Keypad in the Industry

Arm your system in HOME mode and your Entry Sensors protect you. When you're headed out, simply press AWAY and your motion sensors add a second line of defense against burglars. Unlike other keypads, ours is wireless and can easily hang right by your front door.

Handy Menu Options:
Edit System Settings and Send Us Test Signals

With our keypad you can also easily change your Master PIN, add & remove sensors, and send us test signals whenever you want to be reassured that you're safe.

Wireless Motion Sensors

Full Room Coverage

Detects motion within 30 feet, for full room coverage. You can place motion sensors in corners for maximum range. The sensor provides 90 degrees of horizontal protection and 45 degrees looking down.

Pet Friendly

Your dogs and cats under 50 lbs won't trigger the alarm when you're away. We've designed the sensor to be less sensitive to motion close to the ground. For larger pets, consult us to design a custom placement.

Flexible Install

The sensor is shaped to stand on a shelf, adhere to a wall, or fit in a corner for maximum room coverage. Set the sensor to be active only in "away" mode (so that you won't trigger it while you're home) or both "home" and "away" modes (for rooms that you want covered with a motion sensor while you're home).

Wireless Entry Sensors

Protect Your Doors and Windows

Install entry sensors on all types of windows and doors as your first line of defense. When the magnet moves more than 2 inches away from the sensor, it triggers an alarm.

Door Chime

Whenever a door or window opens, the Base Station will sound a door-chime and the sensor LED light will flash. So even when your system isn't armed, you'll know if someone's coming in.

Easy Install

SimpliSafe sensors come with the battery pre-installed, adhesive tape pre-applied, and a particularly strong magnet, making installation a snap.

Wireless Wonders

"With a full array of door and window sensors, plus motion detectors that wirelessly monitor your home for intruders, SimpliSafe is an affordable, but full-featured, wireless security system similar to the expensive, professionally installed ones. Just be sure to remember your pin unless you want to give your neighbors a piercing 85-decibel wake-up call."
