False negatives with AI in BI 6

[n2qew]

I'm working on migrating a BI 5 system to BI 6. Built from absolute scratch, Win 11, 20 / 40 cores, 64 Gig of RAM Nvidia P4000 for GPU.
I'm running into an issue with motion detection / confirmation via AI. I've tried the built in, and CP, and Blue Onyx. The issue is that things of interest are being - generally - accurately identified. The problem seems to be that BI is deciding that they are static. For example, in the attached pix, there's a person walking up the sidewalk. It shows that it knows it's a person, but it false negatives. The "person" ID is flagged with the blue square stating "....objects which do not overlap an area of movement.....". What does that mean? it triggers, AI says person, they are walking, etc. For testing, I've got it doing pre 2 + 10 post with a .333 analyze rate. Alot of those pics show person. You'll note the "eval version " burned in because I'm not ready to move to it until I can get the motion trigger / AI Ironed out. The old version 5 works fine - even when pointing to the Blue Onyx running on the new box for it's AI. So, something is different in 6 that I'm missing.

BTW... If anyone is looking at Blue Onyx, beware of the latest couple of versions as they set off about 20 Virus alerts in Virustotal.

First thing to try is to lengthen the times between each analysis to at least 500ms or preferably 750ms (I would even experiment with 1 second), especially given that your average analysis time is running 337ms (potential for backlog of analyses). Also, no person is going to cross this scene in less than 1/3 second, and more importantly the AI needs to see a difference in each analyzed "frame/image", so better to lengthen that a bit. Head on approach like this is always harder to get right compared to scenes where people move across the field of view.
