If you use default/outdated Firmware you just get "Unexpected error" No indication you need to upgrade firmware.

Describe the bug
This was a complete fluke I found this out, I was trying to get my cameras to connect and it was just showing up "Unexpected error" with literally no error message to explain what was going wrong.
I logged into the camera directly via IP, and noticed it used flash to try and load the stream, googled this, and the reolink website said that in later firmware they fixed this, which made me think, these bloody things dont auto update their firmware!
And after updating my devices firmware the camera got added to HA.

To Reproduce
Use firmware 2.0 (The default that comes with the cameras!)

Expected behavior

1. Show a CLEAR error message to tell you to upgrade your firmware, not "Unexpected error".
2. Link to the reolink firmware page https://reolink.com/download-center/ so people know how to get their firmware.
