The Nest Cam is battery powered, so it can be placed wherever you need it most, inside or out. It knows the difference between people and vehicles, so you can get the alerts that are important to you. Listen and speak through the camera, right from the Google Home app. If something happens, you can check in at any time with 24/7 live view. If you miss a notification, it includes 3 hours of event video history so that you can go back and check what happened. And it’s easy to install yourself - no outlet or wires required.
