New here: question 2k pan tilt + homebase

I bought the 2k Pan Tilt cam and if I like it am looking to expand.

But I have a question: is there an advantage of combining homebase with this cam? Or is there none?

You can’t use the Homebase 2 with the indoor cams, pan & tilt, or floodlights. They use Wifi only and have internal storage. You can run them on the same app, but automations, modes and schedules are separate and can’t be combined with the indoor cams. Homebase has its own communications protocol and storage and works with sensors, keypads, and battery cams.
