Briefly; Eufy has had a lot of problems including "encrypted" streams not really being encrypted (https://www.channelnews.com.au/eufys-chinese-owners-finally-admit-their-security-cameras-were-a-security-risk/) as well as that they are Chinese owned and manufactured.
Ubiquiti is US owned and Taiwanese manufactured; and further I use a complete Ubiquiti networking stack (gateway, switching, wifi) so it was a great fit.
