Does HomeKit Secure Video access 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 2 still works when Eufy IT is down? Anyone tried this?
