Apple announced that EufyCams will be a partner to have the camera clips saved to iCloud storage for free.
This will be a feature of iOS 13 which will be released in the Fall. No word yet from Anker/Eufy about the collaboration. But it seems pretty definite that HomeKit support will be coming to the EufyCam line.
Getting notifications of motion clips with other HomeKit actions (open door, turn on lights, etc) will be really cool. See below.
