Questions about Reolink Home Hub 1

My Home Hub is also in the basement and is connected to the network via a switch. I've connected one camera near the Home Hub to its own Wi-Fi network because the regular Wi-Fi signal isn't strong enough. The other cameras are connected to the regular Wi-Fi network. All the cameras store their data on the Home Hub. From what I've read in Reolink's manuals and tutorials, the problem is that cameras connected via the regular Wi-Fi network always need an internet connection. This means that if the internet goes down, those cameras won't be able to store data on the Home Hub. However, the camera connected directly to the Home Hub can continue to store data without an internet connection. (https://reolink.com/blog/reolink-home-hub/)
