@DonGull,

Were you able to tell if the Tapo cameras were unlinked from your account/app entirely, or were simply not accessible over the network. The cameras may have begun operating and recording as you had set perviously, but they may have not been able to automatically reconnect to your wireless network.

As far as I am aware, the cameras will not be removed from your account without you removing the device or adding the device to another TP-Link ID.

If the cameras are functional and connected, the cameras can go quite a long time without being connected and they will continue to record even if they cant connect to your network or the cloud. I have even spoken with a few users that have configured a few cameras to record without a connection at all, and then they will go and download the videos from the SD card when they visit the home with the camera.

To improve their stability, you would want to provide the best opportunity for the cameras to automaticall reconnect to your network. Consider setting an IP Reservation and then a Static IP for the camera on your network.
