Hi, I have a DS-2CD2042WD-I and a DS-2CD24322432F-IW that works great on Blue Iris individually but when they are both enabled, they constantly go up and down. I found a conversation somewhere but I couldn't find it again about the need to upgrade to the lasted version of Blue Iris. I did that to 4.8.4.2. This didn't fix the collision problem. Is there something else I need to change in Blue Iris to fix this? Thanks
