Google's wire-free indoor/outdoor camera: weather-resistant, magnetic mount, person, animal and vehicle alerts, and three hours of event history free, with Nest Aware needed for longer history. It stores up to an hour of events locally if your Wi-Fi drops. It's a Google Home camera first; Home Assistant gets it through the Google Device Access (SDM) integration, which is cloud-based and needs a developer registration and Pub/Sub setup, so it takes more effort than Ring or Reolink. Worth it if you already live in Google Home.
What can Home Assistant control on the Google Nest Cam (Battery)?
Supported by the core nest integration via Google's Device Access API: cloud-based, and setup needs a Google Cloud project, OAuth and a Pub/Sub topic. Event traits are limited to what the SDM API publishes, so rich Nest app labels may not reach Home Assistant.
