Standalone SDI streaming appliance — broadcast SDI direct to streaming platforms.
Ask us a quick question about this product — signal compatibility, use case fit, or anything technical. We usually reply the same day.
The Ultra Stream SDI is the SDI sister to the Ultra Stream HDMI — the same one-click live streaming workflow but with a 3G-SDI input for professional cameras. Connect a broadcast SDI camera, set destinations once via the app, then press the device button to go live to multiple platforms.
For semi-professional broadcast environments — sports clubs running SDI cameras for streaming, regional broadcast operations doing simple OTT delivery, smaller production companies streaming events — this is the easiest-to-operate SDI streaming device on the market. No streaming PC, no software stack, no production technician needed at runtime.
32GB internal storage allows simultaneous local recording while streaming, useful for archive and as a backup if the stream loses connection mid-event.

Ultra Stream combines encoding and streaming in one portable device with optional local recording. Ultra Encode is designed for fixed installations with more focus on protocol flexibility and multi-destination streaming. Ultra Stream is typically better for event and field use.
Check the specification table above for recording capability details.
The Ultra Stream SDI supports RTMP (YouTube, Twitch, Facebook, custom), making it compatible with YouTube Live, Facebook Live, Twitch, Vimeo and any custom RTMP endpoint. SRT support enables low-latency contribution to broadcast infrastructure.
No. The Ultra Stream range is standalone — configure it once via the web interface or mobile app, then it operates independently without any connected computer.
The Ultra Stream SDI accepts 1x 3G/HD/SD-SDI.
