Blue Iris only detects motion while I am viewing the feed

[ht55645]

I am experiencing a problem with one of my cameras which is a different model from the others, this is the only camera that has this problem and I am trying to pinpoint the fix. I have motion detection set up for the camera through blue Iris, the sensitivity is just right and I have verified that it works. The only problem is I have to be physically observing the feed from the console or the mobile app for it to trigger, otherwise I can walk in front of the camera all day long and it will not trigger. Generally speaking what would even cause this type of problem? It seems bizarre

Just to clarify, yes this is running as a service and yes the other cameras trigger without a feed being pulled up.
