The Smart Video Doorbell features a typical design that includes a 1080p camera at the top with 160-degree lens and built-in motion sensor, two-way communication via built-in speaker and microphone, and a button at the bottom for visitors to ring.
The HomeKit support means that users can receive an instant iOS notification when someone rings the doorbell which enables them to jump straight into the Home app to see who's at the door.
The Apple HomeKit integration also extends to automation rules, so users can set up trigger actions like turning on outdoor smart lights when motion is detected. Other smart services like IFTTT are also supported.
The Netatmo Smart Doorbell stores video on an onboard microSD card and doesn't need a subscription like some other doorbell security systems. Owners can also choose to automatically save videos in a personal Dropbox or FTP server.
On the other hand, Netatmo's product is designed to be a straight doorbell replacement, so a wired connection is required to get it up and running. Pricing information has yet to be disclosed but product availability is expected in the second half of 2019.
