Smart Magnetic Door & Window Sensor — 2.4GHz One‑Key Connect Security Alarm Detector

2.4GHz One‑Key Connect — quick, stable setup for smart home use. The sensor pairs easily and supports simple operation so you can start controlling devices without complex configuration. Real‑time door/window monitoring: the sensor detects open and closed states and will trigger and push notification to the phone. Scene linking and multi-sensor alarms: configure modes such as away from home mode; if an intrusion is detected the device will trigger, push notification to the phone, and can prompt an IP camera (not included) to record. You can also use linked scenes to turn lights on automatically when a door is opened. APP remote control lets you manage status and alerts from anywhere. Compact, easy installation: small footprint with adhesive mounting so the detector can be placed on doors, windows, drawers, and similar locations without altering the appearance or structure of the original furniture.
