These instructions will help in installing Obseron with a GUI on a
CentOS 7 platform. Obseron with a GUI will work as a viewing client and
as a recorder. Installation may differ from the instructions due to
different hardware used for servers. There are only a few mandatory
steps, but all the suggested steps are very useful. These instructions
should not be followed blindly but adjusted to fit your hardware (such
as GPU and drivers for it).
