The Netatmo Welcome connects to Wi-Fi and senses movement. Then, it supposedly recognizes faces and can keep track of whether your family members are home or away.
The camera supports full HD, night vision, and a 130-degree field of view.
It automatically takes snapshots and recordings when it senses movement, but you can customize what it stores and which notifications you get. Everything is stored on an SD card, but can be backed up to the cloud.
Use the app to track who's coming and going.
Supposedly, you can view all stored clips remotely, and get a live view of the camera.
You can customize notifications for each individual.
