Events are how SAFR SCAN reports activity at the reader. It reports either Access Granted or Denied events or Recognition events.   Events include information about the person, location as well as face and scene images.  When SAFR SCAN is connected to SAFR Server, events are sent to the server and archived for a configurable retention period on the server.

If the SAFR Server  goes down while connected to the server from SAFR SCAN, the Event in SAFR SCAN that occurred while SCAN was offline are accumulated in SAFR SCAN, and when the server connection is restored, the cached events are synchronized to the server.

The maximum capacity of cached events is 2000.

Note: If you disconnect from SAFR SCAN to the server in the server settings, the event data accumulated in SAFR SCAN will not be synchronized when connected to the server when server is connected again.

Reliable persistence in Attendance Mode

The following only applies to Attendance Mode (not Access Mode).

Storage of events on scan is designed to be persistent in the event of a power loss.  If network goes offline, SAFR SCAN will begin to store events onto non-volatile memory. This is done in the event that power is lost.  If power is lost, the events persisted to non-volatile memory will also be sent to the server when both power is restored and connection to server is restored.
