You can also use the camera for home monitoring (indoor Nest Cam) which you will have complete control of and can view remotely as if it were any other Nest Cam, the Face Match will be optional upon setup this will ask you to scan your face it will allow 6 people at present to be setup.

The camera can also be switched off by swiping up on the Nest Hub Max however there will be an indicator to show you this is switched off this will still allow the Google Assistant to work (as long as you have the microphone switched on).

The microphone, audio and camera can be switched off whenever you feel necessary.

The microphone and camera kill switch is located on the back of the Nest Hub Max, you can have this switched off permanently, however, I would prefer to keep this on when using this in the kitchen, if my hands have food all over them, the built-in camera will allow me to pause and play music/videos with hand-gestures.

This is additional to voice and touch control from the previous Nest Hub.
