I've got a FI9831W here ready to be played with. Recovery image is available and, of course, the serial console is connected to my trusty USB-TTL-adapter.
My biggest gripe with the camera is the WebUI - which ONLY lets you log in with the stupid IPC plugin installed. And that's only available for Windows and Mac - no Linux.
So what alternative WebUIs are there? I'd LOVE to get something like the INSTAR WebUI which works without any stupid browser plugin on any modern browser. But I've already checked and the INSTAR devices run mostly on Grainmedia SoCs and have a different partition layout. And their recovery manual only talks about partition 6 and 7. No word about the other 5. The only real candidate would be the IN-6011HD firmware, which is a HiSilicon, too. But I assume they use the OEM WebUI for that, not their own one. And I know that from a Wansview NCH-536MW already.
Any other hints?
EDIT: So from poking around in the uBoot, this thing has a 16MB SPI Flash memory and 192MB RAM. Partition layout is: hi_sfc:1M(boot),4M(kernel),11M(jffs2). SoC is a HiSilicon Hi3518. (IN-6011HD is a Hi3511.)
