Door And Window Sensors

Know when doors or windows open

Door and window sensors are the foundation of a smart home security system. These compact devices detect when a door, window, or entry point opens or closes and instantly send alerts to your phone or smart home hub.

Use them to monitor front doors, back doors, windows, garage doors, cabinets, and more. Door and window sensors can also trigger automations—like turning on lights when you arrive home, sending notifications if a door is left open, or activating a siren when unexpected activity is detected.

Our selection includes reliable Z-Wave, Zigbee, and Matter-compatible door and window sensors from trusted brands. Designed for long battery life, strong wireless performance, and seamless integration with leading smart home platforms, these sensors help keep your home secure and connected.
