Why is BI sending a pre-trigger image to the AI some 7000ms before the event?

Can anyone explain why BI why is sending a pre-trigger image to the AI some 7000ms before the event?

See attached image.

I can't seem to find a setting for this.

There is nothing unusal about the AI settings, other than I want to scan 10 images at 100ms intervals with a cancel condition that is aways false (we don't have bears in the uk ). Changing these settings doesn't appear to make much difference in any event

Any ideas?

Is that part of the periodic sending of the image to AI to check for static images?

Not sure, but it only seems todo it on this camera. What i would expect to see is an pre image @ T-100 (the 100 being the AI image interval)
