Just bought 3 C220 cameras for looking after elderly family member and have had sd card initialize issues and the 2 way calls and talk is so chopped up that they can't understand me. I've seen this could be down to sound suppression issues. Can these be fixed?

Everyone seems to have issues with SD card compatibility issues why? I've seen even people with the big name cards like SanDisk have problems. If you provide a sd card slot at least make it easy to use. I'm not paying for yet another subscription service! What can I do about this?

I've only started using 1 so far as I was unable to properly setup the sd card so paused. 

If all of this can't be fixed I'll be moving to a different make.
