It can be done without IFTTT, look at Blue Iris camera trigger from smart things
Sorry, I’m in a hurry, the link above he made it so smartthings would trigger BI to record a particular camera, I edited it so a motion detection in smartthings would allow me to set a particular PTZ preset for a camera.
To make a camera in BI work as a smartthings motion detector, look at Blue Iris motion detection to activate smart app or [WITHDRAWN] Camera HTTP Motion Endpoint . So, if your system was already in an armed mode, a motion detection would indeed alert you and could also be told to turn on a light, all depends on what you want for your circumstance. Maybe I’m not following your needs?
