Scale changes this problem rather than simply enlarging it. A group with offices, plants, campuses or branches in many places needs the same question answered the same way in all of them, and the usual route to that is to send everything to one central system and decide there.
That route creates a second problem. Pooling video, recordings and identity material turns many modest targets into one very attractive one, moves sensitive material between departments and borders that may not be permitted to share it, and leaves every site depending on a link staying up. In many organisations the rules governing the material simply do not allow it.
The checks below run where the material already is. Each site works on its own and keeps its own record, so what the organisation gains is a common standard and a reviewable trail, rather than one place where everything sensitive was collected for the sake of convenience.
