The Netatmo Smart Video Doorbell lets you see and speak to visitors, even when you're not home. Watch video of visitors or deliveries via your smartphone and talk to them live, whether you're at home or on the other side of the world. The Smart Video Doorbell also helps protect your home with person detection and the Alert-Zones feature. You can receive real-time notifications if someone is acting suspiciously outside your door, without also getting unnecessary alerts or false alarms. There are no subscription fees. All the Smart Video Doorbell features, video storage and updates are included with purchase. The Netatmo Smart Video Doorbell is easy to install and adapts to most electric installations (8-24V and 230V). Smart and straightforward - thats the thinking behind its design. If you already have a wired doorbell with a chime, simply replace the bell and keep your current chime. Then connect the doorbell to your Wi-Fi. Your data is always kept fully secure, with videos encrypted and stored locally a on the Smart Video Doorbell's microSD card. You can also back up your data by adding automatic storage to the cloud via Dropbox or FTP server.
