Hi,
What do you mean by closing the TP-Link account?

1. If you have deleted your TP-Link account as per the following instructions, you are unable to recover it. 
How can I delete my TP-Link cloud account?

In this situation, you can register a TP-Link account again using your email address. Then, factory reset your camera and reconfigure it to bind to your TP-Link account.
What is TP-Link ID, and how to create a TP-Link ID?
 

2. If you have not deleted your TP-Link account, usually, you can log into the Tapo app with it to control the Tapo devices bound to it.

Best Regards
