Your intelligent sensors notify you even before someone can break in. They are installed on the doors and windows of your choice and trigger a warning message at the first sign of a break-in attempt by detecting vibrations. The sensors also notice when a door or window is suddenly opened. In such cases, you will be immediately alerted via your smartphone. This gives you valuable time in the event of a break-in attempt. Monitor your doors and windows directly through the app: Keep an eye on your home by setting up the app accordingly. This way, the sensors can alert you via your smartphone as soon as a door or window has been left open for too long. Are you on the go and have doubts? Check all doors and windows equipped with sensors to see if they are open or closed. Installing your sensors is hassle-free: Maximum intelligence and simplicity – that’s the motto of Netatmo products. These door and window sensors are no exception. The single-piece sensors are waterproof and can be easily attached to any door or window, regardless of the brand. To function, only a smart indoor camera from Netatmo is required. The door and window sensors, together with the smart indoor camera and the indoor alarm siren from Netatmo, form a complete alarm system that protects your home and reacts immediately in case of a break-in. You can even trigger the alarm siren through a selected sensor. The alarm siren and sensors only work with the smart indoor camera from Netatmo. A maximum of 1 alarm siren and 12 sensors can be connected to each camera.
