Mixing eufycam 1 with 2c

Hi

I currently have 4 eufycam1 with homekit1. I am considering using a few eufycam2C at strategic location.

Could someone or @AnkerSupport who are using mixed version please advice on the following .

  1. Is it possible to have both homebase 1 and 2 connected and active and running on one mobile app? If so, does the eufycam 1 and 2 display/event are displayed on the same preview pan together? Or did you have to switch homebase?

  2. Is it possible for homebase 2 to link with eufycam1

Thanks
