It allows monitoring not only from the actual location of these cameras, where you have specially equipped monitoring systems, it also allows doing it from any other IP-enabled point of the world using special video surveillance applications, like web browsers (see image below). The fact that IP cameras and servers can be accessed over an IP network is a great benefit. Like IP cameras, video servers also convert image from analogue cameras to digital form and provide access to it through an IP network, but they also provide additional options for video archive creation (for this reason, video servers are equipped with hard drives). Instead of this, they are equipped with several video input connectors (usually from 1 to 6), and the user may plug any analogue camera he would like to these connectors. Video servers are much more sophisticated devices, and usually come without cameras.
