Hi,
Usually, the detection video clips won't record for only 2 seconds. In your situation, please confirm the following information for further analysis.

1. Ensure your router is working fine and it provides a normal and stable internet connection.

2. You can try to factory reset a camera, reconfigure it, and check if it helps.

3. If the problem remains:  

    1) Go to the camera's Device Settings > Detection page, send us pictures of the enabled detection types and activity zones, and check if the event happens within the activity zones but is not recorded.

    2) Reproduce the issue, record the whole motion manually on the camera's Live View page, then download the corresponding cloud video clip from the Tapo app, and send us the video recordings.
 

Note: The cloud server does not support storing continuous recordings, it supports storing detection video clips only.

Best Regards
