About recording
l
The maximum file size cannot be larger than a quarter of the total available space on the SD card.
For example, the maximum file size limit for a 64 GB SD card is 16 GB. A warning appears if you set
a file size limit that is bigger than a quarter of the SD card capacity.
l
If you set the file size limit and then swap in a smaller SD card, you must change the file size limit to
a smaller size using the Admin panel if the file size limit is bigger than the SD card.
l
Recording with a file size limit that exceeds the size of the SD card will corrupt the SD card.
l
Newer recordings overwrite oldest recordings when the amount of free space on the SD card (or
M.2 SSD) is less than the configured recording file size limit.
l
If recordings are selected for Automatic File Upload (AFU) while AFU is at maximum upload capacity
or when AFU is unavailable, the recordings are added to an upload queue. If there is no available
space left in the SD card (or M.2 SSD), new recordings fail and do not overwrite recordings in the
AFU queue.
l
The SD card is formatted for Ubuntu systems and is not compatible with Windows and Mac devices.

l
We recommend using large capacity SD cards such as 256 GB or a large capacity M.2 SSD when
using Pearl Nano with a CMS. Do not schedule recordings that are longer than the capacity of Pearl
Nano to store the recording to the storage medium.
For information about recording to Content Management Systems (CMSs) like Kaltura and Panopto, see
CMS recording and webcasting control
. For instructions on how to use Pearl Nano's front screen to
start/stop scheduled recordings for a CMS event, see
Stop/start scheduled CMS events using the front
