No. BI after motion saves the picture in folder and AI Tool looks in this folder for a new pics, when AI Tool finds a new pic in this folder it sends it to Deepstact to analyze. BlueIris doesn't talk to AI/Deppstack.
There is an option in AI Tool dynamic masking but I don't know how it works, never tried. Probably it can create "temporary" a mask after it sees a car in the same location for several minutes. Masked area won't trigger alert
Deepstack knows nothing about the movement, it looks only at still pictures. It's like a filter. If you record the street where cars are parked then my sugjestion unselect "car" in AI Tools. Otherwise, you will get alerts each time deepstack sees a car.
Username and Password for BlueIris Account. You can enter here BlueIris usename and password, and in camera trigger / cancel url use [Username] , [Password] variables instead.
At 5:17 AI/Deppstack recognized the first person, after this 2 min cooldown means the next recognition will be after 5:19. You are correct cooldown means AItools won't look at another image for 2 min.
I think you don't need to install any additional os. Try search deepquestai, like in this instruction #4: (4 .CREATE CONTAINERS DOWNLOADED FROM THE DOCKER HUB REGISTRY)
