Introduction

These are the settings that control the recording and storing of track data in the system database. Tracks and all the individual track sightings can be recorded in real time as they are detected and tracked by the software. This is a powerful feature that enables detailed analysis of the system not only to improve performance but also analyse incidents. Witness supports easy to use queries that allow users to quickly retrieve and display historical track data so operators and engineers can see exactly why incidents occurred and to review what happened on the site.

Clean Tracks Period (days): The period of time at which tracks expire and are cleaned from the database.

None: No tracks are recorded.

Incident: Only tracks which are been responsible for breaking a rule are recorded.
