Sometimes after playing with the IVS setting within the camera, I have to run the Find/inspect again within BI to get the alerts functioning properly again.
Since this is a new camera, you may check that Onvif user is active on the cameras account setting.
I had one camera that was not providing alerts until I turned on BI's built in motion sensor along with Onvif/camera events under the Motion/Trigger tab. Onvif started triggering and when I unchecked the "motion sensor", it continued to function well, providing Onvif alerts only
