Users on the free plan receive Video Previews which are up to 10-seconds in length. Canary will begin recording an event when motion is first detected, and the first 10-seconds of that motion will be captured and placed on your timeline.
For users with Canary Membership, a video event may be as short as a couple of seconds and up to ten minutes in length. Canary will begin recording an event when motion is first detected, and continue to record all motion throughout a ten minute window.
If your device continues to detect motion for longer than ten minutes, a new video event will be created on your Timeline for the next ten minute window, and you will receive a separate notification for that event.
