Smart Door & Window Alarm Sensor — 2.4GHz One-Key Connect Smart Home Security, High Sound, App Remote Alerts

Compact smart door/window sensor with 2.4GHz One-Key Connect for quick, hassle-free setup. The 2.4GHz protocol provides a stable, fast connection so the device is simple to operate and easy to use. Detects door and window status — when opened or closed the sensor is triggered and sends push notifications to your phone. Link multiple sensors to create alarm scenes (for example: Away from Home mode); if an intrusion occurs the system triggers and pushes an alert to the app. APP remote control puts home monitoring in your hands wherever you are. Small, adhesive-backed design for easy installation on doors, windows, drawers and more without damaging the appearance or structure of existing furniture. High Sound alarm for clear audible alerts.
