Recording continous

I have 6 or seven cameras, different models. All of them start to rewrite the micro SD right after 12AM . How do I set them to write continous to the SD card?

I’m using 128GB SD cards, they don’t begin to copy over until they are full.

I also am using 128 GB cards. Actually I have 11 cameras on two different wifi networks and all of them start to rewrite the cards right after midnight. I don’t know why.
