Product details:

Nest Cam is wire-free, so it goes almost anywhere, outside or in. It knows the difference between people, animals, and vehicles, so you can get the alerts that are important to you. Listen and speak through the camera right from the Home app. Check-in anytime with 24/7 live view. If you miss a notification, you can always go back and see what happened with 3 hours of free event video history.
