The Google Nest Cam IQ Indoor Triple Pack consists of 3 smart IP cameras that recognize people. With the supersight function, the cameras automatically zoom in to follow every movement of the person, with a clear view. You'll receive a push notification on your phone when the camera detects people it doesn't recognize or when your children come home from school. The cameras have 3 built-in microphones and a speaker that's 7 times more powerful than its predecessor. In combination with the noise suppression and echo cancellation, you're in loud and clear contact with the person in your home. Are you expanding the cameras with a Google Nest Aware subscription? If so, they can remember familiar faces. This way, you can make sure that you only receive a notification when your partner comes home, but that a recording is started when an unknown person appears on the screen.
