Meeting with Multiple Input Sources

In medium to large meeting rooms, it’s common to use multiple video sources — such as two cameras and two different presentation feeds (e.g., PowerPoint slides and videos). The CAMLIVE™ PRO 4K supports up to four HDMI sources, enabling it to efficiently manage and switch between these inputs. This allows for a smooth integration of both presentation content and key participants into the video stream, eliminating awkward delays or gaps typically caused by manual switching.

Live Lecture

The CAMLIVE™ PRO 4K allows large conference rooms to stream professional grade content to global employees and stakeholders through video software. The intuitive front panel control makes it easy for you to quickly switch between multiple HDMI cameras and presentations on laptops. Produce professional content without the need to hire professionals.

The Aten UC3430 4×1 HDMI Multi Viewer is a high-performance solution designed for professional AV applications requiring multi-source monitoring on a single display. With four HDMI inputs and one HDMI output, this compact device allows seamless switching and simultaneous viewing of up to four HDMI sources in different screen layouts, such as quad view, picture-in-picture, or full screen.

Built with reliability in mind, the UC3430 is ideal for surveillance rooms, broadcast setups, classrooms, and control centers where real-time monitoring and efficient screen management are essential. With intuitive controls and superior video quality, it offers a plug-and-play experience without compromising on performance.
