Vizrt NSP4KIO Spark Plus I/O 4K - FG-002795-R001

Product Overview

The Vizrt Spark Plus I/O 4K (FG-002795-R001) is a compact bidirectional NDI-to-HDMI video converter supporting UHD 4Kp60 resolution. It converts HDMI video sources — cameras, computers, presentation systems, and display devices — to NDI for distribution across IP networks, and decodes NDI streams back to HDMI output for monitors and displays. Powered via Power over Ethernet, it requires a single network cable for operation, making it a practical tool for broadcast, corporate AV, and live event production teams integrating HDMI sources into NDI workflows.

Product Description

The Spark Plus I/O 4K encodes HDMI video at native UHD 4K resolutions up to 2160p60, converting the signal to NDI for delivery to TriCaster systems, 3Play replay, software production tools, or any NDI-compatible destination on the network. In decode mode, the unit receives an NDI stream and outputs it over HDMI for display on monitors, projectors, or downstream video equipment. A simultaneous HDMI loop output allows the source signal to pass through to a local display while the NDI stream is transmitted over the network. Analog audio is supported via a 3.5mm input for embedding and output for de-embedding. PoE operation eliminates the need for a dedicated power outlet at the converter location, reducing installation complexity behind displays, on presentation carts, or in AV rack positions. Program and Preview tally LEDs provide on-device status indication, and the web-based UI enables remote configuration from any browser. NDI virtual input support extends compatibility to Zoom, Skype for Business, Microsoft Teams, and other NDI-aware applications, making the Spark Plus I/O 4K useful in both live broadcast and corporate AV production contexts.

Key Features

• UHD 4Kp60 HDMI-to-NDI Conversion — Encodes HDMI video at up to 2160p60 for NDI distribution over IP networks.
• Bidirectional Operation — Single unit handles both HDMI-to-NDI encode and NDI-to-HDMI decode.
• HDMI Loop Output — Simultaneous pass-through loop keeps the local display active while the NDI stream is transmitted.
• Power over Ethernet (PoE) — No external power supply — single Ethernet cable handles data and power.
• 3.5mm Analog Audio I/O — Line-level audio embedding and de-embedding at the converter position.
• Program and Preview Tally LEDs — On-device LED indicators for on-air and preview tally status.
• Web-Based Configuration UI — Remote configuration and monitoring from any network-connected browser.
• NDI Virtual Input Support — Compatible with Zoom, Teams, Skype for Business, WebEx, and other NDI-aware applications.

Frequently Asked Questions

Does the Spark Plus I/O 4K support true 4K60?

Yes. The FG-002795-R001 supports UHD video at up to 2160p60 in both HDMI-to-NDI encode and NDI-to-HDMI decode directions.

Can it simultaneously loop the HDMI output to a local monitor while streaming NDI?

Yes. The unit includes a simultaneous HDMI loop output that keeps the local display active while the NDI stream is transmitted over the network.

Does it need a power supply?

No. The device is powered via Power over Ethernet (PoE). A PoE switch or PoE injector is required on the network.

Is this compatible with TriCaster systems as a 4K HDMI input source?

Yes. The Spark Plus I/O 4K outputs NDI, which TriCaster systems accept as a native input source, allowing any HDMI device to appear as a 4K NDI source in the TriCaster input list.
