Introduction to Open Edge Insights for Industrial
=================================================

.. note:: Open Edge Insights for Industrial (Open EII) was previously named as Intel® Edge Insights for Industrial (EII) and Intel® Edge Insights Software (EIS). Remnants of the previous names still exist in some components. The name replacement is ongoing and will be completed in future releases.

Since its inception in early 2018, Open EII has been focused on enabling the rapid deployment of solutions aimed at finding and revealing insights on compute devices outside data centers. The title of the software itself alludes to its intended purposes: 

   **Edge** :- systems existing outside of a data center.

   **Insights** :- understanding relationships. 

This software consists of a set of pre-integrated ingredients optimized for Intel® architecture. It includes modules that enable data collection, storage, and analytics for both time-series and video data, as well as the ability to act on these insights by sending downstream commands to tools or devices. 
To learn more about the Open EII v3.0 key features and improvements, refer to the Release Notes.

This guide will detail the capabilities of Open EII ingredients and will serve as a reference for developers working with them. This guide is designed to enable developers to create custom solutions for their end customers. In this document, all the terminology will use Open Edge Insights for Industrial (Open EII), Intel® Edge Insights for Industrial (EII), and Edge Insights software (EIS) interchangeably to refer to the same software, and will be fully updated in the next release. 

.. note:: 
  
  * In the documentation, some of the reference links and images are not accessible. This is due to the limited access to the GitHub repositories. You can access the missing content in the next version of the EII user documentation.
  * EII uses the evaluation license for Matrix Vision SDK available at [WORK_DIR]/IEdgeInsights/VideoIngestion/mvGenTL_Acquire-x86_64_ABI2-2.44.1.tgz. While using a non-Matrix Vision camera, after ingesting 200 images, a watermark appears. To remove the watermark, buy a complete license or use a Matrix Vision camera, or integrate the respective camera SDK (for example, Basler camera SDK for Basler cameras) in the Video Ingestion or the Edge Video Analytics microservices.
