Hi,

I have a VIGI C250 camera (firmware 2.2.1) recording continuously to a 128GB SanDisk microSD card in 3-minute segments.

I need to access the individual video files stored on the SD card with their original filenames and timestamps, in order to verify recording continuity and detect any potential gaps.

The VIGI PC Client merges all segments into a single file during download, which does not allow me to verify individual file timestamps.

My questions:

1. Is there any way to access the individual SD card files directly from the camera via FTP, HTTP, or any other protocol?

2. If I remove the SD card and connect it to a PC, what filesystem format does the camera use (FAT32, exFAT, ext4)? Will the files be readable directly on Windows with their original filenames and timestamps?

3. Is there any other method to browse and download individual 3-minute recording segments with their original timestamps?

Camera details:
- Model: VIGI C250
- Firmware: 2.2.1
- SD card: SanDisk 128GB
- Recording mode: Continuous, Main Stream, 3-minute segments
