@Solla-topee hello 👋 Thanks for the advice, since posting my last query I actually purchased a SanDisk Extreme 512GB Micro SD card A2 U3 Class 10 and that has been recognised on the camera hub...

I have purchased 2 C420 cameras with a hub and am in the process of setting them up. I formatted and input a 512GB micro SD which it doesn't recognise at all so decided to switch it out for my 128GB...
