I have just received C800 (I91BM) and the ANNKE firmware (V5.5.102 build 200925) only shows "Basic Events' - Hope this helps clarify.
Alerts 'on cam' are not an issue for me though, as I use Deepstack with BlueIris for AI detection.
I have a Windows 10 VM set up on Unraid server, with a GTX 1050...
