I wish I could answer. I have no idea, and I didn't care that much to disassemble the firmware and find answers. What I know is Reolink doesn't care about Linux and web UI, or in their own words:
> the web browser remote access is only available via the IE browser
You're fine. RLK8-410, unlike RLK16-410, offers a functional web UI that works on Chrome on Linux. It's flash based though. RLK16-410 offers no web UI on Chrome whatsoever so that's troubling.
I've just posted a 1 star review on Amazon:
The UI doesn't work on Linux browsers. The page says: "Please left-click the following icon to download and upgrade the plugin. Please restart the browser after upgrade." and it links to download DvrWebClient.exe. That's a step back from Reolink 8CH NVR that worked on Linux browsers just fine. I'm hugely disappointed. I wouldn't have upgraded if I knew that.
