I think you're suppose to turn off default object detection since you're using cpai. Also in the TO CONFIRM box you need to input the object you want cpai to confirm as a CONFIRMED ALERT. Try that?
I have this camera on my apple silicon Mac mini with security spy the presets take like 2 seconds before movement starts. When I call the same presets on blue iris 5 demo I'm running on windows 10 it takes various more seconds before movement happens.
