A:Answer DoubleA, that will largely depend on if you pay for their recording services or not. You get 30 days of Nest Aware for free, and while you have that or any other subscription, it actually records 24 hours a day, but how long that video is kept is dependent on which package you're paying for. You also have some liberties in setting up what you want to be alerted for as the Nest can determine the difference between a person and a pet, and can alert you only if it sees a person nearby, or if it detects any motion at all. If anyone rings it, it will automatically notify you and provide a clip of that person walking up to the door.
