An intuitive and secure graphical user interface on the classroom computer provides teachers with control of all audio and video devices within the classroom, including projectors, audio amplifiers, DVD players, document cameras and more. When the streaming video option is in use, teachers have full control of video-on-demand content. Typically with a single button press, and often requiring little or no training, teachers can easily adjust the volume level in the classroom, turn devices on and off and select from multiple video and audio sources. Classrooms may also implement wall mount button panel to provide room control without a PC.
