Homebase 3 additional units

Hi

I have two cameras operating successfully but need another two which would be out of the range of the homebase 3 unit. Can I purchase additional homebase 3 units and do I have to pair the new cameras with the new homebase 3 unit and the original homebase 3? Will the eufy security app manage / stream the cameras regardless of which homebase 3 unit they are connected to?

Also, currently the only option in the United Kingdom is to get a homebase 3 packaged with cameras. Will there be a standalone homebase 3 made available on the UK webstore?

Thanks in advance for any assistance. It’s the first time I’ve installed security cameras and so far it’s been easy. The additional cameras required that would be outside the range of the original homebase 3 is a bit of a headache though.
