These classrooms are prepared to hold classes and other events in a hybrid environment.

These rooms are distinguished from the others by the following characteristics:

    • Presence of a video camera placed on the ceiling that allows a better capture of both image and sound of the classroom.
    • The video camera allows the definition of scenarios (presets).
    • The video projection is in HDMI.
    • 2 Active speakers placed on the wall next to the boards.
    • A control system that allows you to turn on/off the video projector; turn on/off the video camera; choose the predefined shooting scenarios.
