I did not know what was the best spot to post this, I was looking for suggestions on door bell camera, Something that has speaker, mic and works well with BI.
Thanks
If you only need it to work with BI, then this: Review-Dahua DB-11 Video Door Bell
Beware, that it does have many quirks if you want to use it with its app.
I'm not aware of one that is fully ready for prime time.
YMMV
