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 :guilabel:`Settings` -> :guilabel:`General`. After you are finished with adjustments, click :guilabel:`Update`. Find the detailed explanation of each general setting below.

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 :ref:`camera group <camera-groups>` and :ref:`watch list <create-list>`.

Thumbnail JPEG Quality
============================================

Subject to JPEG quality, thumbnails may take up a significant amount of disc volume. Use the :guilabel:`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.
