But Netatmo says it's offering everything at no additional charge. > The SkyBell HD doorbell has free seven-day cloud storage, and August doorbells come with free 24-hour cloud storage. But Netatmo is the first to give us all three features for free. Keep in mind that person detection isn't the same as facial recognition -- it won't tell you who it sees, just that it sees a person.
