Glossary: Video Server

A video server takes an analogue video input and lets you use it over an IP network. It does this by digitising the analogue signal and serving it through an IP network. This then allows access to the digital stream over your LAN or the internet.

Video servers can come with different numbers of ports, the most common are one port and four port. Multiple port video servers allow you to view each stream individually or all the streams on the same page. The video server assigns a unique address to every stream so they can be added to other applications as standalone streams.

A major advantage of using a video server is that it allows you to use old, non IP cameras through a digital interface. This means that it can enable the same features and benefits as IP camera technology. These features can include analytics, motion detection, event logging and recording. Using a video server is a cheap way of upgrading an existing CCTV camera installation to the IP age.

Another big advantage of using a video server with existing CCTV cameras is that it can allow remote access to them from anywhere in the world.  This is handy for people who want to check on a site from home or people who want to access their camera on the move.
