Bi-directional video allows for private video conferencing between classrooms, as well as live video broadcast announcements to be made to the entire school. Teradon provides bi-directional broadband wiring configurations, which means each classroom becomes a point of video origination. In addition, we provide the ability to archive and store all broadcast video that can be accessed on demand. Administrative override allows for one channel automatic interrupt of all other channels on the video distribution network. The administrative override system is highly effective for emergency instruction as well as important school updates and announcements. Override can be initiated from any video distribution drop on a given distribution network.
