Epiphan Lecture Capture Plus Bundle

Epiphan Lecture Capture Plus Bundle combines an Epiphan Pearl Nexus Live Video Production System with two EC20 4K SDI/HDMI/NDI/Dante PTZ cameras for synchronized multi-angle lecture capture and professional video production. Pearl Nexus handles recording, streaming, and software switching, while the two EC20 cameras provide remotely controlled acquisition with 20x optical zoom and UHD-capable HDMI output.

For broadcast engineers, AV teams, and education technology departments, the bundle brings camera acquisition, signal management, recording, and streaming into one coordinated workflow. Pearl Nexus accepts 3G-SDI, HDMI, USB UVC, and RTSP/SRT/HX/NDI sources, while each EC20 adds HDMI, 3G-SDI, LAN, and USB-C output together with Dante AV-H, NDI|HX2, ONVIF, RTMP/RTMPS, RTSP, and SRT streaming.

Highlights

• Two-camera lecture capture package – combines a Pearl Nexus production system with two Epiphan EC20 PTZ cameras
• Multi-format Nexus input architecture – accepts 3G-SDI, HDMI, USB UVC, and RTSP/SRT/HX/NDI network sources
• 20x optical PTZ cameras – each EC20 uses a 6.25 to 125 mm lens with 20x optical and 16x digital zoom
• Professional IP video workflows – EC20 supports Dante AV-H, HTTP, NDI|HX2, ONVIF, RTMP/RTMPS, RTSP, and SRT
• 1TB internal SSD storage – provides onboard recording capacity for lecture capture and production use

Why It Helps

Two PTZ cameras give a lecture capture operator more framing options than a single fixed source. One EC20 can hold a lecturer or presentation position while the second covers a wider classroom view, alternate presenter, or another part of the room, giving recorded content a more useful multi-angle structure.

Pearl Nexus serves as the central production point for those sources. Its SDI, HDMI, USB, and network inputs allow engineers to combine camera feeds with other video sources, while simultaneous HDMI and RJ45 outputs provide confidence monitoring and network delivery from the same chassis.

The EC20 cameras are designed for repeatable remote operation with 255 presets, 325° pan, 120° tilt, tally, and PoE+ support. Combined with the Nexus system's 1TB internal SSD, the bundle is suited to recurring lecture capture environments where camera positions, recording, and streaming need to remain consistent from session to session.
