Archives and Live Streaming
While operations in this section are basically the same for administrators and
ordinary users, the difference lies in their rights. The administrator can view
and modify all recorded files currently archived by the system and live
streamed video through the Web UI, and delete archives. Ordinary users can
only view and modify recorded files and live streaming videos on which
they are authorized to perform such operations. For description of Archive
page, see Archives. For description of Live Streaming page, see Live Streaming.
