I haven’t. I can’t speak to Eufy specifically, but battery-powered wireless cameras are not ideal. Battery-powered or wireless individually isn’t ideal. I think most battery cameras won’t do continuous recording, and with wireless, expect lag issues.
I just swapped my Ring doorbell, which did motion detection recording, not continuous, for a ubiquiti g4 doorbell pro. That got continuous recording, which is so much better. But I opted not to run an Ethernet cable, which I’m kind of regretting now. I was using Homebridge for Ring and Ubiquiti to get the cameras into Apple home.
On the other hand, Eufy is probably much cheaper and simpler to set up. So if you don’t care about continuous recording and you can deal with lag, it’s probably a good option.
