Cause

Need a way to determine which side of a dual reader door a valid access event has taken place.

Resolution

Compare the door’s TimeEntered attribute to the TimeExited attribute, if TimeEntered > TimeExited then the event took place at the entry side of the door, otherwise it took place at the exit side.

The same technique can be used for Invalid Attempt events using the door’s InvalidEntryTime and InvalidExitTime attributes
