I would recommend to look at this topic:
https://community.home-assistant.io/t/eufy-camera-integration/
There are essentially 2 solutions:
@bropat 's iobroker based solution. This exposes a host of options (including video) but requires a more complex setup including running iobroker next to ha
@matijse 's mqqt bridge. From your post this looks most logical as a fitting solution. Add GitHub - MaxWinterstein/homeassistant-addons to you add-on repository and install. Make a separate admin user within eufy and use this to login on the add-on.
You will need mqqt on ha, but with that combination you will have sensors (doorbell pressed/ motion detected / last activity image) up and running in no time.
The referenced topic includes a host of information.
