To calculate the FindFace host(s) characteristics, use the requirements provided in this chapter.

.. tip::
   Be sure to learn about the FindFace :ref:`architecture <architecture>` first.

Basic Configuration
===============================

.. important::
   If the resolution of a camera(s) in use is more than 1280x720px, it is strongly recommended to use the GPU-accelerated package ``findface-video-worker-gpu``. 

.. note::
   In the case of a high-load system (~> 15 events per second), we recommend using an SSD.

.. note::
   You can also use an Intel-based VM if there is AVX2 support, and eight physical cores are allocated exclusively to the VM.

Required Administrator Skills
================================

A FindFace administrator must know and understand OS Ubuntu at the level of an advanced user.
