Acquire or import
Use Document or Photograph scan modes for a compatible scanner, or import an existing file into the evidence record.

Local case data
Keep investigation records under local control.
Investigator Professional is a Windows desktop application built around locally stored case data. Password controls and application locking help protect access to the working system.
Continuity and retained records
Protect the working record without erasing its history.
Investigator Professional combines local access controls with backup validation, retained case records, and read-only activity history.
Validated backup and restore
Create a .tipbackup archive containing the case database and managed evidence files. Restore uses manifest validation, staged restart, a pre-restore safety copy, path-containment checks, and rollback protection.
Append-only activity history
Review the latest 500 recorded create and update events for clients, investigations, people, and evidence in a read-only history view.
Close and retain
Close investigations while retaining their records. Database guards prevent hard deletion of client, investigation, people, and evidence records.
