Please check whether the detection feature works properly on the D130, if not, that means no face info was submitted to the H500. 

<answer> Yes, I have enabled Motion, Person, Pet and Vehicle Detection on D130 and they are working fine for many months now for event recording and notifications.

Try to power cycle your Tapo H500, see if it helps.

<answer> Yup I did rebooted Tapo H500 so many times already, but didn't help.

By the way, do you have both Tapo C246D and TC70? Are they all new devices like the D130?

<answer> Yes, I have various existing Tapo cameras like TC70, C246D and C320WS, and all work flawlessly with Tapo H500 and all sends new faces for recognition to Tapo H500 successfully. It is only the D130 that doesn't work, despite the detection feature working fine. It just doesn't submit new faces for recognition to Tapo H500.

I see a simliar problem also reported with D130 not sending new faces to Tapo H500 here --> https://community.tp-link.com/en/smart-home/forum/topic/841412

Really wanted the D130 to work as it is well positioned outside at the gate to see new faces of strangers for facial recogntion. 

Thank you for the kind assistance.
