Camcorder file system?

Question

CCTV

Good afternoon, I have TANTOS video cameras in my hands, it became interesting how to open their file system in order to change the web interface.
Just curious to see how it all works =)

Answer 1

Either FAT or ext2, the third is not given.

Answer 2

1) Open the camera.
2) Find the memory chip (there will be something like this: AT25DF161-SH-T)
3) Google this chip (by chip size and marking), find the datasheet.
4) From the datasheet, you learn commands for reading / writing to the chip (usually using the SPI protocol)
5) Read the chip, determine the file system (most likely, there is FAT).
6) Edit the web interface.
7) Rejoice
This is all provided that there is no encryption on the FS, but this is unlikely to happen in a conventional camera.

Answer 3

In the firmware, you can flash the web interface separately. Inside the firmware file there is web.tar.gz
But it is difficult to sort through the firmware.

By type of activity (if anything, it is in the profile), we rarely see live video surveillance systems, but often - fallen, or exposed to intruders.
I can’t speak unequivocally about the equipment of this company, but often it all depends on how video surveillance is organized in you. It may well be that you do not have any file system (except for the one on which the software necessary for operation lies). Accordingly, there are no files.
Instead, a proprietary video stream, which is a wild mixture of frames from different cameras. If necessary, we write custom programs to recover videos as files, but I doubt that it makes sense for you to do something like that.
Only if it really itchs. Writing your own system for working with camera recordings from scratch will be very difficult.
