What's new in release 4.13?
We've made some awesome changes in firmware 4.13. Integration with AV Studio is replaced with Epiphan Cloud -
your new destination to remotely manage and operate your Pearl Mini devices. We also made it easier for you to
troubleshoot installations with more diagnostic tests and statistics. And we added support for Dynamic DNS(DDNS)
and DHCP Option 81, making sure you have seamless access to Pearl Mini on the network even if a DHCP server
changes Pearl Mini's IPaddress. Plus more enhancements are available in this latest release.
Firmware 4.13
Epiphan Cloud support
Manage all your Pearl devices from Epiphan Cloud with a diagnostics dashboard for remote rescue troubleshooting,
configurable email alerts, channel creation and configuration from the cloud, confidence monitoring, batch
operations, remote firmware updates, and more! It's easy to get started with a free Epiphan Cloud account. For
details, see: www.epiphan.com/cloud/
Diagnostic tools
Diagnostic tools are added to the touch screen and Admin panel so you can instantly check the connectivity status of
Pearl Mini, get the external IPaddress of your Pearl Mini, and more. From one easy location, you can run network
diagnostics like ping, traceroute, test the network upload/download speeds, confirm domain name resolution, and
probe to see if a network port is open on the network side.
Scheduled AFU
Now you can schedule file uploads to only occur during a specific period of time every 24-hours. Recordings that end
within the configured time period automatically upload right away. Recordings that end outside the upload time
period are queued up and upload when the scheduled upload time period is reached.
DHCP Option 81 (FQDN) support
Ensure your Domain Name Server (DNS) always has Pearl Mini's most up-to-date IP address mapped to Pearl Mini's
Fully Qualified Domain Name (FQDN). Option 81 support means you can keep using Pearl's FQDN no matter how
many times the DHCP server may change Pearl's IPaddress. Pearl Mini automatically asks the DHCP server to tell the
Domain Name Server (DNS) to update Pearl Mini's record with any changes to Pearl Mini's IPaddress or FQDN.
Dynamic DNS (DDNS)
If the DHCP server doesn't support Option 81, no problem. Enabling DDNS ensures that whenever the DHCP server
changes Pearl Mini's IP address, Pearl Mini informs the Dynamic Domain Name Server (DNS). Use Pearl Mini's FQDN
without worry because the domain name records are always kept up-to-date. Custom, dyndns.org, and noip.com
DDNS servers are supported.
Panopto low storage alerts
Now you can configure Pearl Mini to not send low storage alerts to Panopto.
SHA hashing algorithm support
We added support for SHA-256 and SHA-512 hashing algorithms for HLS (push) and MPEG-DASH stream
authentication.
Changes affecting remote login using AV Studio
AV Studio is going away
AV Studio is being replaced by Epiphan Cloud. You'll now see Epiphan Cloud instead of AV Studio in the Admin panel as
a configuration option. When the switch over occurs, Pearl Mini devices that are currently paired with AV Studio
automatically migrate to Epiphan Cloud. Previously uploaded recordings and scenes related to AV Studio's post-
production tools are not accessible from Epiphan Cloud. After updating Pearl Mini to firmware 4.13, all pairing
functions from the Admin panel link to Epiphan Cloud. To access your devices, simply create a free Epiphan Cloud
account or use your AV Studio credentials to login to Epiphan Cloud at: https://go.epiphan.cloud
