Eufy cam 2 pro compatability

Will eufy cam 2 pro work with my existing base station that has 3 eufy cams on it, or do I need the base station 2? Then will my old cameras work on the new base station. I am looking to add better resolution in a few areas.

It helps if you specify what homebase you have currently have. There are 3 different models. Older cams generally work on the newer homebase units. I have 4 cam Es on my homebase 2 and they work fine.
