this Topic is specific for the Tapo-Camera-Control Integration , do you not have this Integration ?, if not you should search in the Forum for ONVIF help
Yes indeed, the more “Specific” information you can provide, in a structured manner, the better
In regards to this integration (Tapo: Cameras Controll), you should then first follow the installation instructions, and then follow the instructions for adding your cam. If any of this fails, you can ask for help, providing the “steps you have performed, and where/how it fails for you” Also then with a sample of relevant “logfile/error codes”
In general, with this integration, (default) you should not open any Ports, to WAN, but that depends upon how you have your ha-system And Your Router configured, you show a picture of PORT-forwarding, dont “play” with this if you’r not familiar with the consequences.
How your system/router is configured only you know, and should you need help with that , it’s the general Forum, if there aint are a specific Topic for your router ( i can say, i haven’t even heard of the name)
So with your limited knowledge, Don’t start with the most complicated, just start with adding your device, in correct/preferred integration. IF that is ONVIF , then read the official ha-docs for this, and ask questions in regards to this on the Forum
If it’s for this Integration (Tapo:Cameras Control), again start with basin(getting your cam installed in this integration)
When things works the “default” way you can move on to more advance features, such as port-forwarding, ONVIF etc. … in respective Topic’s or common integration/configuration Topics
