I have a question about H200 Hub camera connection limits

I’m planning to purchase the H200 Hub.

According to your website, it supports up to four cameras or doorbells. However, I remember reading about a user who connected nine cameras to their H200 Hub on a forum that I no longer remember from where.  I also saw an Amazon review from someone claiming to have six cameras connected to the H200 hub.

This has left me a bit confused. Is there an actual limit to how many cameras can be connected to the H200? Or is four just the recommended number for optimal performance?

Does performance drop after connecting more than four devices?

I currently own one C120 camera and plan to buy six more, for a total of seven cameras. I only intend to use them for event recording, not continuous 24/7 recording.

Thank you in advance.
