About this item - See When Your Door Opens: Stay informed about your garage door's status in real time with open/close notifications sent to the Garage-Control Cam. - Never Worry About the Battery: Install a battery in the Garage Door Sensor and forget about it for a year; you’ll even receive a reminder when it’s time for a replacement. - Easy to Install: Setting up the Garage Door Sensor is straightforward. Just stick, hold, and release it using the 3M sticker, or fasten it with screws. Finally, integrate your entire security system by pairing the Garage Door Sensor with the Garage-Control Cam. - Note: The Garage Door Sensor is compatible only with the eufy Garage-Control Cam and Cam Plus. Homebase is not supported.
