Does HomeKit Secure Video need Eufy IT Connection?

I noticed this article:

You can use the eufyCam 2 and eufyCam 2c exclusively with HomeKit Secure Video…
Hands-on: Rolling out HomeKit Secure Video for eufyCam 2 and 2c

Does this mean that HomeKit access to the Eufy Homebase still works when Eufy IT is down? Has anyone tried this?

Yes, hksv works independent of the eufy servers.

OK thanks… not sure I understand all the connection points but appreciate the info. The Homekit connections on my other devices seems very reliable.
