Pearl Nano User Guide
About Opencast recording
The Pearl supports scheduled events, recurring events, and unscheduled ad hoc recordings. Scheduled events start and end automatically. No manual intervention is required. After the event ends, recorded files automatically upload to Opencast. Backup recordings are also saved locally on Pearl. If the network connection or the CMS goes down during an event, Pearl continues to record locally and uploads the recording when network connectivity resumes.
Pearl Mini and Pearl Nano - A large capacity (256 GB or more) SD card (or a large capacity SATA M.2 2280 SSD on Pearl Nano) must be installed to record events. Do not remove the SD card while files are uploading to Panopto.

General Information
- Starting or stopping a scheduled VOD event before the scheduled start or stop time does not change the event into an ad hoc event.
- Pearl Nano must be registered with Opencast to record and stream Opencast events, see Enable CMS and register with Opencast.
- Scheduled events have priority over ad hoc events. If an ad hoc event is still in progress when it's time to start a scheduled event, the ad hoc event is stopped and the scheduled event starts.
- Scheduled VOD events automatically start recording locally on Pearl Nano even If the network is down or Opencast is unavailable. After the session ends, the locally recorded files upload automatically to Opencast when the network link to Opencast is re-established.
- If the network connection is lost during a file upload to Opencast, the transfer automatically restarts when the network connection re-establishes.
- If Pearl Nano loses power while a scheduled event is being recorded, the recording stops. If Pearl Nano is powered back on before the scheduled end time for the event, recording of the scheduled event restarts automatically and a second set of files are created.
- If Pearl Nano was unavailable on the network or powered down and misses a scheduled event, the status of that event appears as Skipped on the Events page in the Admin panel.
- Do not use AFU or configure recording file size, type and other channel recording settings when CMS is enabled on Pearl Nano.
Pearl Nano information
- Pearl Nano - You can start and stop events earlier than the scheduled time, as well as pause an event using the Admin panel or the front panel control key interface on Pearl Nano.
- Opencast treats the channel you setup on Pearl Nano as a single video-source event for recordings. For ad hoc events, the default name of the uploaded recording includes the date and start time of the event. For example: 2019-07-15 08:00. A more intuitive name can be entered when the ad hoc event is created.
- For more information on using the front screen of Pearl Nano to start and stop events, see Stop/start scheduled CMS events using Pearl Nano's front screen menu.
- To monitor the channel during an event, you can display the Channel view on Pearl Nano's front screen, see Confidence monitoring using the front screen. You can also monitor the channel using the Admin panel or see a live preview of the channel and the audio level from the remote recorder page in Panopto.
