I have concerns/confusion about if the H500 hub will work for my setup. Will my wired cameras still work as wired or does every camera need to connect straight to the hub wirelessly?

I have these camera wired to a POE switch/Ethernet. I want the 24/7 footage & clips stored.

2 x C310 v2 (1 can be clips on due to limits until you allow the planned 6)

3 x C325WB (2 v1 & v2, v2 will be POE only) 

Also need to backup these clips only.

2 x C460

2 x C425 v2

1 x C125

All are on compatibility lists.

Also if I happened to lose power to that hub (working on getting a UPS already) or the internal network is down.. are the wireless cameras still recording to the SD card as backup? Then they will backup to the hub again once it shows up online?
