The file format i can see is exfat that is what should be used i guess.
Except that some devices may format an exFAT file system using a File Allocation Size which is incompatible with macOS. Windows is able to read a lot of exFAT variations, but macOS is much more limited here. Whenever someone wants to share an exFAT drive with Windows I always recommend using Disk Utility on the Mac to erase the drive so the exFAT drive can be used with both macOS & Windows.
I wonder if your DashCam is able to work with other variations of the exFAT file system? Only way to know is to use macOS Disk Utility to erase the SD card and see if the DashCam is Ok with it. Some devices may erase an SD card if it is not in the proper format so keep this in mind if you use Disk Utility to erase the SD card, but the card is not readable after using the SD in the DashCam.
