What's new in release 4.14.1?
Firmware 4.14.1 adds some innovative new features to Pearl-2, like the new Content Management System
(CMS) event start screen that you can lock. A great solution to simplify starting and stopping events or when
installing Pearl-2 in classrooms and unmanned kiosks. For Kaltura, you can now webcast to a pre-configured
streaming URL destination. And for Panopto, we made it possible to upload a locally recorded version of a
webcast and replace the original webcast version. Plus we added some other new items and fixed an issue
that affected the video encoding quality.
Firmware 4.14.1
Upload local webcast recording to Panopto
Pearl-2 now records Panopto webcasting events locally and uploads the recording so that the Panopto server
uses the local recording from Pearl-2 instead of the original webcast. You can disable this feature using the
Admin panel.
Locking CMS start screen
Configure Pearl-2's touch screen to show the Content Management System (CMS) events screen at start up.
Add a PIN to restrict user access to the start screen. Locking the start screen is useful when operating Pearl-2
in public spaces, classrooms, and unmanned kiosks.
Pre-configured stream URLs for Kaltura webcasts
When you create a Kaltura webcasting event on Pearl-2, you have the option to use the primary and backup
URLs supplied by Kaltura or to choose a stream destination URL that is created locally for the channel on
Pearl-2.
Schedule CMS event uploads
You can define a time period when Pearl-2 can upload Content Management System (CMS) event recordings
to the CMS server. Recordings made outside the upload time period are queued until it's time to start
uploading.
Adjustable fan speed
Your Pearl-2 will sound a bit different after the firmware update because we changed the fan speed for better
internal cooling. We also added some controls for you to adjust the fan speed using the Admin panel.

v
What changed in this release
Unpairing from Epiphan Cloud using the touch screen
We listened to your concerns about people inadvertently unpairing Pearl-2 from Epiphan Cloud and so we
removed the unpair option from the touch screen. You can still unpair the device using the Admin panel or
directly in Epiphan Cloud.

Pearl-2 User Guide Start here
Start here
Welcome, and thank you for buying Epiphan Pearl-2™, Pearl-2 Rackmount™ or Pearl-2 Rackmount Twin™.
You'll find information on how to set up and use all three models in this user guide. Whenyou see the name
Pearl-2 used in this guide, it means that the content applies to all three models. Differences are explicitly called
out. For a product description, see What is Pearl-2?.
See the Quick start for basic steps to get a single video source (and optional audio) set up so you can stream
and record some output right away. The rest of the guide shows you how to tweak the system exactly how
you want it so you can take advantage of the many advanced features.
Pearl-2 is fully integrated with Kaltura and Panopto Content Management Systems (CMSs) and is easily setup
using the Admin panel. The Integration section of this guide details how to register and set up Pearl-2 as a
remote recording and streaming device for Kaltura and Panopto.
For information about using Pearl-2's RS-232 API, HTTP API, and HTTPS API with third-party applications, refer
to the Pearl System API Guide.
About this Guide
After the introductory section and quick start, the next chapter describes the main user interfaces that are
used to operate and configure Pearl-2. You'll find everything that you need to use and setup these interfaces :
l Touch screen
lAdmin Panel
lEpiphan Live
The rest of the user guide covers setting up and operating your Pearl-2 system for a successful experience.
The chapters are organized into these main categories: Setup, Capture, Stream, Record, Integration,
Maintenance, and Troubleshooting.

Pearl-2 User Guide What is Pearl-2?
This guide assumes that all feature add-ons for Pearl-2 are activated. If a documented feature or task is only
available when a specific feature add-on is activated, it is indicated by a link to the activation page for that
feature add-on. For the 4K add-on, the link is 4K .
What is Pearl-2?
Pearl-2 is a versatile live video production device that's a video encoder, video streamer, live switcher, and
video recorder all in one. Pearl-2 comes in three models.
Pearl-2 Pearl-2 Rackmount Pearl-2 Rackmount Twin
A small, silent, portable
system that comes with a
hard-shell carry case.
A 2U rackmount system with all the
same functionality as the portable
Pearl-2, but designed for installation
and operation in a rack.
A high density 2U rack mount
variation that contains two complete
(and independent) Pearl-2 systems.
With Pearl-2, you can capture, record, and stream from computer monitors, radar displays, or almost or
anything with a wide variety of supported video input signals, including:
lSDI (up to 12G)
lHDMI™
lHDMI 4K4K
lDVI-I(single link)
lUSB
2

Pearl-2 User Guide Feature add-ons
lSRT and RTSP
lNDI® and NDI|HX (Alpha channel supported)
Capture audio from XLR, RCA, USB, SDI, HDMI, and network sources (SRT, NDI, and RTSP).
Simultaneously capture up to six full HD video sources or up to four 4K sources if you have the 4K feature
add on installed. You can create up to five simultaneous channels for live switching, or a single 4K channel.
Have separate ISOs or create custom layouts with multiple video sources and picture in picture. You can do all
that with Pearl-2.
Stream to Content Distribution Networks (CDNs) worldwide using modern protocols SRT, HLS, and MPEG-
DASH. At the same time, you can stream to other destinations using RTMP/RTMPS, RSTP, or NDI. Even
multicast directly to viewers on your LAN so they can watch the live channel broadcast using a web browser or
media player on smart devices connected to the same private network as Pearl-2.
Download recordings using your web browser, or set Pearl-2 to automatically upload recorded files directly to
a network server using FTP, RSYNC, CIFS, WebDav, and more. Pearl-2 is also fully integrated with Kaltura and
Panopto Content Management Systems (CMSs) and can be registered as a video remote recorder resource for
seamless lecture capture plus user authentication directly from Pearl-2's touch screen.
Network security compliance with 802.1x protocols, passwords, and certificate authentication means an
easier setup for IT friendly live streaming over enterprise networks. Pearl-2 is HTTPS enabled for secure
administration and control over the LAN, and supports secure live streaming protocols like SRT with AES
encryption and RTMPS.
Pearl-2 does not capture from HDCP encrypted sources.
Feature add-ons
Pearl-2 offers add-on features so you can do even more with your system. Start from the base model of Pearl-
2 and add feature add-ons for extra functionality.

Pearl-2 User Guide Feature add-ons
See Add-ons overview for details about the availability of add-ons for your system, as well as instructions to
purchase and install add-ons.
Where you see this symbol 4K in the guide, that means the feature or function applies only if you
have activated the 4K feature add-on.
