How high do you think it is?
I think the SUAS might have been at 400 feet, and possibly not committing any offences in doing so. Without details of where and when this took place, it's hard to decide if there was any wrongdoing. The spotter, if there was one, ought to have heard and seen the approaching helicopter, but you should also consider that the operator may not have been looking at the view that you see here. Sometimes it makes more sense to look at the craft rather than the screen.
I accept that seeing it at 400 feet is tricky task, but local rules might differ to how the CAA demand that commercial operators do it here.
The data file that is linked to the video would make interesting viewing.
