Home Automation integrations with security camera system

Anyone have any experience integrating their smart home functions with their security cameras? I am switching to an IP camera based system and I'll be using BlueIris as my base software, so there's a lot of potential for integrating my automated stuff. If you've done this, what kind of routines did you set up? I'm thinking about doing some stuff with facial recognition for the people who live in my household, but that'll depend largely on if it's reliable enough.
