SRT Gateway vendor hub · Last updated: June 30, 2026

Datavideo SRT gateway workflows connect source-side jobs such as NVS encoders, event contribution, venue networks, SRT ingest, operator monitoring to a controlled live video operations layer. Datavideo NVS encoders are often used as practical event contribution devices. Callaba provides the receiving gateway and operational layer after the NVS output leaves the venue network.

Quick answer: where Callaba fits

Use the Datavideo device or platform for the source-side job, then use Callaba as the SRT listener, cloud gateway, private gateway, recorder, Multiview surface, playback layer, route controller, and API-controlled operations plane.

Workflow pattern

Datavideo source to Callaba SRT gateway

Source side

Datavideo device or platform

Encode, contribute, decode, or hand off the live feed from the production edge.

→

Callaba gateway

Receive, monitor, route, record, recover

Use SRT stats, preview, Multiview, output state, failover, and API control to operate the stream.

→

Outputs

Multiview, recording, playback, partner output, backup path

Turn one contribution boundary into a workflow the team can inspect and reuse.

Setup checklist for Datavideo SRT workflows

Confirm the exact Datavideo model, firmware, role, output type, and SRT support before the event.
Create a Callaba SRT server and choose the listener port, latency, stream ID, and passphrase policy.
Open the required UDP port or port range on the firewall, AWS security group, or private network boundary.
Configure the Datavideo source as SRT Caller for most cloud workflows, then point it to the Callaba host and port.
Verify connection state, incoming bitrate, RTT, packet loss, preview, audio, and recording before relying on the feed.
Only after ingest is stable, add Multiview, playback, routing, partner output, failover, or API automation.
