I am curious if anyone has had any luck figuring out the IVS auto tracking with the newer firmware versions. It seems Dahua took away the ability to have any control of it by removing the Calibrate tab in IVS. I have tested and tested, tweaked it left and right, and nothing seems to have any real effect. In some ways, it seems better to only enable IVS and not create any rules, set target filters, or any of the other adjustments they left. That seems to work just as well or better...to only enable it with no configuration. It gets obsessed with the tree trunk and moving leaves in my front yard. It will be panning across tracking something and sometimes will lose it by stopping to focus in on the tree trunk or leaves. I see no way of excluding them. Maybe I'm missing something?
