custom build arcnet not detecting faces far away?

I've recently switched to using this custom build, in order to get more unknown detections. This seems to work, but one thing i noticed it doesn't seem to detect as much faces/from a far anymore.

They use the same face detection mechanism i assume, so is it discarding more faces up front? Is there anyway to adjust this? With the default build i could detect people and their faces from at the end of the road, with the new arcnet build you have to be less then 2 meters away it seems.

Compare the custom arcnet build with the default build, focusing first on the face-detection behavior described in the report. Reproduce the difference using faces at varying distances and determine whether the custom build drops detections earlier; done means identifying a confirmed cause or documenting the relevant detection setting.
