STEP 2. Server and Software Requirements
==============================================

.. _step2:

Server Requirements
----------------------

:term:`FindFace Lite` requires different server configuration depending on the type of processed information (image or stream) and on quantity of used camera and :term:`identity authentication terminals<Identity authentication terminal>`.

Image processing
+++++++++++++++++

For image processing, when :term:`identity authentication terminal<Identity authentication terminal>` detects a face and sends a result to FindFace Lite, server requirements are the following:

| **Devices Quantity** | **Physical Intel Cores >2.4 GHz** | **RAM, GB** |
|                      |                                   |             |

| 1 – 8                | 4                                 | 6           |
+----------------------+-----------------------------------+-------------+
| 8 – 16               | 4 – 6                             | 8           |
+----------------------+-----------------------------------+-------------+
| 16 – 24              | 4                                 | 8           |
+----------------------+-----------------------------------+-------------+

HD (720p) live streams processing
++++++++++++++++++++++++++++++++++

For detection while processing HD (720p) live streams (20 FPS) server requirements are the following:

+----------------------+-----------------------------------+-------------+
| **Devices Quantity** | **Physical Intel Cores >2.4 GHz** | **RAM, GB** |
|                      |                                   |             |

+----------------------+-----------------------------------+-------------+

FHD (1080p) live streams processing
+++++++++++++++++++++++++++++++++++++

For detection while processing FHD (1080p) live streams (20-25) FPS server requirements are the following:

+----------------------+-----------------------------------+-------------+
| **Devices Quantity** | **Physical Intel Cores >2.4 GHz** | **RAM, GB** |
|                      |                                   |             |
