ABSTRACT
In between the fully analog and fully digital systems, there are several solutions that are partly digital, that is, systems that incorporate both digital and analog devices. This has led to some confusion in the video surveillance industry today, as some talk about a “digital” system to mean analog cameras that connect to a DVR (digital video recorder), whereas others use the term to describe a network video system with network cameras. Although there are digital components in both systems, there are some very important distinctions to make between each of the systems.
