Hi,
Typically, there are the Tapo Care Basic plan and Tapo Care Premium plan available. For the Tapo Care Basic plan, you can add up to 5 cameras, for the Tapo Care Premium plan, you can add up to 10 cameras.

No matter where the cameras are located, if they are bound to the TP-Link account that subscribes to the Tapo Care service, you can add the camera to the Tapo Care plan until the quantity limit is reached.

How to add new cameras to my Tapo Care plan

Best Regards
