Hey Brian
I’m not 100% sure why there’s a 32gb/64gb limit.
I’m currently testing a 256gb Micro SD
Not sure if there’ll be any degradation in the video using a card that large.
I have my camera recording continuously 24/7 and I extrapolated a timeframe of 26 days when the card will be filled.
If it stops recording earlier than that I’ll report it here.
Even though it’s seeing 238gb of available memory when I first formatted the 256gb card it’s possible when I get to 64gb it could stop recording or go to where it starts deleting I think 1 hour at a time.
It’s also possible the video may be corrupt if it goes by the 64gb limit.
So for now I’m still testing the 256gb SD card.
If I have no issues I’m thinking of going to test a 1tb card.
Not that I need 1tb or even 256gb, I’m just tinkering.
Stay tuned!
