I have IVS rules set up in the zone of the interest and they work fine.
Now, I want to additionally recognize movements outside of the zone but I want these to be separate in the timeline as they are not that important to me and I want to be able to separately search for IVS and Motion events.
that's why I want to use motion so it shows in yellow and not blue here:
I don't know but can check tomorrow at the NVR.
How does it show if you only search for MD and search again only for IVS now that you've changed the settings? I bet that if you search with both clicked IVS would be the dominant trigger and would be displayed as blue, in your case.
