I have been doing this for a while now, but, got caught out on the IVS rules!
It didn't jump out at me in guides or other forum answers until @wittaj pointed it out.
After setting up IVS rules, make sure to Find/Inspect the camera in Blue Iris again, otherwise it will never work, at least not on version 5.6.xxxxx
Maybe this has changed but it tripped me up and no mistake.
Hope that might help someone and thanks to @wittaj for noting it elsewhere.
