When a motion and/or audio event occurs, the indoor camera will record five seconds pre-event and 25 seconds after. The entire 30-second video clip is immediately uploaded to the Cloud storage and notifications are sent for you to review the event. 
If the camera is offline, making the Cloud unavailable, the clips are temporarily stored on the provided SD Card. When the camera is back online, it will upload clips to the Cloud. That way you'll never lose a video clip, even if the camera loses the internet connection.
