Tailgating.
One badge swipe, two people through the gate.
Who came on site today?
Badges, gate cameras and visitor logs matched into one record of who came on site, who is still there and where the records disagree.
See it worked throughThree records of the day.
None of them agree.
The badge system, the gate cameras and the visitor book each tell part of the story. In an evacuation or an incident, nobody has the whole list.
Paper visitor books.
Contractors sign in by hand, often illegibly, and rarely sign out.
Who is still here?
At a fire drill, the roll call is built from records that were never matched.
