The FindFace general settings, such as generic confidence thresholds for face recognition and thumbnail JPEG quality, determine your system functioning and resource consumption.

Generic Confidence Threshold
===============================

FindFace verifies that selected faces belong to the same person (i.e. match), based on the pre-defined similarity 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 person 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.
