Please read those links the others listed. But here is the summary:
There are 2 recordings, online (Wyze calls these “Events”) and local/SD (Wyze calls these “View Playback”).
The 12-second limit only applies to online recording. Local/SD recording has no time limit. It will record as long as there’s motion and/or sound. Also SD recording can either be continuous, or event-only. Your choice.
