Not how many entered — who is inside right now

An access record is a number; a presence list is an answer. This page describes how that answer is produced and when it should not be trusted.

One pool

Everyone in the building sits in the same list; which group a person belongs to is the badge on the row.

  • Staff
  • Visitor
  • Contractor

Arrived, not arrived, late

Everyone who passed the gate and appears to be inside; the row shows the entry time and the gate name.

Occupancy and the three-colour band

Occupancy is the ratio of people inside to the capacity the institution entered; the institution sets the capacity, we do not invent it.

Drawing showing the green, amber and red bands

  • Green: you are comfortably below capacity.
  • Amber: capacity is close; a queue starts at the gate.
  • Red: capacity is exceeded; restricting entry is the institution's decision.

Peak hour and gate queues

Hourly density is measured per gate; the hour at which a single turnstile is not enough comes out of the report, not out of a guess.

Separating staff and visitors

When a student count is requested, staff, visitors and contractors are removed from the list; the number states which groups it includes.
