I've linked a help centre article below that explains how to setup your Nest Cam Indoor. Do let us know what happens when you try these steps? Try to be as detailed as possible so we know how best to advise.

Wondering if you still needed assistance with this issue? Please let me know!
It looks like we haven't heard back from the OP so I'm going to go ahead and lock the thread. If you have any further questions or concerns, feel free to create a new thread.
Have a great day,
