How to

Tell visitors and strangers apart

1 Home and away

Like most security cameras, Netatmo’s Welcome can track your location through its app on your iPhone. You can link it to other family members’ phones too, so it knows when your home is empty and to keep watch.

2 Face to face

Netatmo’s Welcome was one of the first security cameras to use face recognition. As soon as you turn it on, it starts to note each new face it spots. Then you just hold a finger on a face in order to identify that person.
