Wyrestorm NHD-120-TX AV over IP Encoder / Transmitter, 1 Channel, 4K UHD, H.264, H.265, AAC, LPCM, PoE

Distributing 4K video across a network often means compromising on latency, bandwidth, or image quality. The Wyrestorm NHD-120-TX solves this by encoding pristine 4K UHD content into an efficient IP stream that travels over standard Gigabit Ethernet, delivering ultra-low latency and flexible bitrate control for professional AV installations.

Who is it for

This encoder is built for integrators and IT managers in corporate, education, and hospitality environments who need reliable, scalable AV distribution. It suits conference rooms, lecture halls, digital signage networks, and video wall setups where multiple displays must receive synchronized, high-quality content from a single source.

Main features

• Encodes 4K UHD video up to 3840x2160 at 30Hz 4:4:4 or 60Hz 4:2:0, ensuring sharp, color-accurate images.
• Supports H.264 and H.265 compression with variable bitrate from 15 to 300 Mbps to optimize network traffic.
• Ultra-low latency of less than one frame keeps video and audio perfectly synchronized for live applications.
• Power over Ethernet (PoE) eliminates the need for separate power supplies, simplifying installation.
• Includes RS-232, IR input, and IR output for seamless integration with control systems.
• HDCP 2.2 compliant, allowing transmission of protected 4K content.
