Wyrestorm Network HD NHD-400-TX 4K AV Over IP Encoder Ex Demo

Wyrestorm logo

This is an ex-demonstration item being sold with all original packaging. Please contact us for more information.
As part of the new WyreStorm NetworkHD 400 Series, the NHD-400-RX streaming encoder offers stunning 4K HDR video, multi-channel audio support and 4K/2K auto-scaling to seamlessly handle mixed resolution sources, content and display devices for matrix and video wall functionality when used in conjunction with a NHD-400-RX receiver.

Unlike a traditional fixed matrix, the adaptable modular matrix design of NetworkHD allows for a system to be expanded quickly and easily by simply adding more sources or displays to meet the needs of any commercial or residential application without requiring an update to existing network architecture. Using standard networking technologies, NetworkHD enables literally any point on the network to support the latest 4K video and HD audio, with PoE providing power to all components from the switch, eliminating ugly power supplies and potential points of failure from a system.

Featuring HDCP 2.2 support, the 400 Series handles the delivery of visually lossless 4K UHD with HDR content and multichannel audio up to Dolby Atmos and DTS:X with ease, making it ideal for AV distribution around the home. Intuitive control can be achieved with the award-winning free NetworkHD Touch app for iPad to create a simple drag and drop switching experience with live video previews of all connected sources and displays. Integration with third party control systems, including the WyreStorm Enado control solution and Control4 is a breeze.
