Central controller
The central control controller (control server) is the core element of the control system. As a rule, it is a programmable device which, thanks to the use of IP technologies, supports a variety of interfaces and allows any device to be included in the system.
The central controller sends commands to the devices according to the set scenario: for example, if you want to start showing a movie, the projection screen is unfolded, the windows are dimmed, the projector and acoustic systems are turned on.
