Often, emergency responders must consider a multitude of factors, such as installation, testing, support, redundancy, and training, before making video component procurement decisions. The guide provides an overview of video systems, defines functional concepts of video quality, explains how to generalize a use case with a use class, and provides a brief explanation of the qualitative aspects of video components. Emergency responders involved in the procurement process - of a video system either in part or in its entirety - will find this guide valuable because it considers an end‐to‐end system. For example, this guide identifies needs associated with a video stream as it travels from the scene (camera) through the system to the end user viewing the scene on a remote display.
There is a wide range of information that exists related to video quality and selection of video components such as installation, maintenance, training, and interoperability. While this guide does not provide detailed specifications and standards for video components, the Video Quality in Public Safety Working Group plans to release future guidance on technical performance specifications and standards that address various components of the video system.
