WiFi Smart Door Sensor for Home Security with Free App Alerts

The door sensor itself does not include a chime; however, you can program it to some smart voice devices via the Smart Life app. When the sensor is triggered to open or close, the voice devices will act as an alarm or bell for 10 seconds. You can utilize the door sensors to safeguard liquor & medicine cabinets, gun safes, storage lockers & boxes. Place a sensor on your fridge/freezer door or lid to know if it was left open and prevent food loss.

Easy Installation: The door alarm comes with 2 AAA batteries, metal screws, and 3M tape, making it easy to use right out of the package.
