Door communication

I see in the bindings that bticino is supported as door communication.
I’m interested in having a version with a camera , which as far as I know bticino has.

yet when I look at the binding page for bticino, it takes about Bticino as My Home Automation .
and I don’t see any examples of door communication.

is this possible with bticino (or another advised technology?)

if so where can I find info on what to use/buy?
