I am glad to hear that you are interested in subscribing to Nest Aware! If you have any of our Cameras or Doorbells, I would definitely suggest you get a Nest Aware subscription! I'd love to provide you with some helpful links explaining what it's all about. Do you have a Nest Aware subscription? If you did, you could look back at that data as long as the event is saved.
Please let me know if you need further assistance.
