General Settings

The FindFace Multi general settings determine your system functioning and resource consumption. Here they are:

  • generic confidence threshold

  • thumbnail JPEG quality

  • schedule for automatic events/episodes cleanup

The general settings for faces, bodies, and vehicles are provided separately, depending on the enabled recognition objects.

To configure the general settings, navigate Settings -> General. After you are finished with adjustments, click Update. Find the detailed explanation of each general setting below.

In this section:

Generic Confidence Threshold

FindFace Multi verifies that objects match (i.e. two faces belong to the same person), based on the pre-defined confidence threshold. The default threshold is set to the optimum value. If necessary, you can change it.

Note

The higher is the threshold, the less are chances that a wrong object will be positively verified, however, some valid photos may also fail verification.

Tip

You can configure the confidence thresholds individually for each camera group and watch list.

Important

The default generic confidence threshold is optimal for the majority of recognition cases. We do not recommend changing it on your own. Be sure to consult with our technical experts prior (support@ntechlab.com).

Thumbnail JPEG Quality

Subject to JPEG quality, thumbnails may take up a significant amount of disc volume. Use the General tab to configure the parameter.

Automatic Event and Episode Cleanup

Use the same tab to schedule automatically purging old events and related episodes from the database. For example, you can purge matched and unmatched events/episodes on different schedules and purge only full frames.
