Use SRT for high-quality, low-latency video streaming

The Secure Reliable Transport (SRT) protocol uses the latest in live streaming technology to keep your productions looking great. Add a remote guest or contributor over SRT to bring professional-quality sources into your Pearl-powered productions.

Switch video sources live

Pearl-2’s built-in touch screen makes it easy to switch between your video sources and layouts during live productions. Alternatively, use the browser-based Epiphan Live interface to switch sources from almost anywhere using a desktop, laptop, or mobile device.

Deep Kaltura and Panopto CMS integrations

Full API integrations streamline lecture capture and enterprise communication workflows. Simply register Pearl-2 with Kaltura or Panopto to start using the encoder for scheduled, multi-camera VOD events, ad hoc events, and webcasting – no complex programming required.

Integrate with your Crestron System

Integrate Pearl-2 hardware encoders more easily into Crestron AV systems with the Crestron-developed Control Module for Pearl encoders. The bulk of the coding is done for you. Build upon the Crestron driver’s existing code base for secure, API control over HTTP or HTTPS.

NDI® and NDI|HX for network video production

Pearl-2 supports NDI and alpha channels for broadcast-quality video with low-latency over Gigabit Ethernet networks. No extra HDMI or SDI cables are required. The system accepts video and audio from a wide variety of NDI-enabled devices and cameras on the network, and it’s just as easy to share the output from Pearl-2 with other NDI devices on the network.

Advanced networking

Take the “work” out of your network setup and configuration with Pearl-2’s auto-discovery feature and built-in touch screen. The touch screen lets you view and reconfigure your IP address right from the device and offers quick access to helpful networking tools like connectivity diagnostics. You can also access these and other networking features through Pearl’s web-based UI.
