Hazard sensors that detect floods, and other threats to your home. Powerful sirens that can help stop intruders in their tracks. That’s the unmatched combination that separates SimpliSafe Home Security from the others. At SimpliSafe, we believe everyone deserves to feel safe at home. That's why our bundles are designed to be effective yet affordable. And with no long-term contracts or hidden fees. This 8-piece wireless security bundle provides 24/7 protection from the outside in.

The smash-safe Keypad is soft to the touch, easy to use during the day and night, and requires no plug so it can be placed anywhere. Entry Sensors (4 total) protect your doors, windows, and cabinets and are designed to blend into the background. And the Motion Sensor is designed for human detection, not pet detection.Advanced security, whole home protection. There's no safe like SimpliSafe.
