SRT relay server for unstable 4G/5G
The SRT protocol has become one of the main choices for live streams on mobile networks. Unlike traditional protocols, it was designed to handle packet loss and instability common on 4G and 5G connections. The goal is not to eliminate every internet problem, but to reduce its impact and keep the stream flowing even in less predictable conditions.
Why SRT is widely used in IRL streams
On mobile networks, small packet losses happen constantly. SRT monitors the stream in real time and requests again only the data that did not reach the destination correctly. This process helps preserve video quality and reduces the chance of noticeable freezes during the live.
More stability on mobile connections
During streams on the move, signal swings caused by antenna changes, network congestion, or coverage variations are common. SRT was built for these scenarios, allowing you to tune latency according to connection quality and maintain a more consistent video flow to the cloud studio.
Integration with cloud OBS
When the signal reaches the server, it can be used as an Ingest inside the cloud studio and added to your Scenes normally. If a significant connection interruption occurs, configured automations detect the problem and show a temporary hold screen, preventing viewers from seeing a frozen image or an abrupt stream drop.
RTMP remains an important alternative
Despite the advantages of SRT, RTMP is still widely used for compatibility with apps, cameras, and streaming equipment. That is why the ideal setup supports both protocols: use SRT when stability is the priority and RTMP when compatibility is the most important factor.
Use the full potential of SRT
Connect your mobile streams to a cloud studio prepared to handle network swings and keep your operation stable.
View plansQuestions about SRT relay
- What latency should I set on a 4G connection?
- Start with conservative values and reduce gradually as connection stability is confirmed. Chasing the lowest latency on an unstable network usually increases the chance of freezes and quality loss.
- Does SRT fix coverage problems?
- No. The protocol helps compensate for momentary packet loss, but it does not replace a working connection. In areas without coverage or with extremely weak signal, the stream will still face limitations.
- When does RTMP make more sense?
- RTMP remains an excellent option when the gear used does not support SRT or when the stream happens on a stable network, such as a wired connection or reliable Wi-Fi.
- Does SRT relay benefit YouTube and Twitch streams equally?
- Yes. The relay acts before delivery to platforms, helping preserve the quality of the signal that reaches the cloud studio. From there, each platform processes the stream according to its own settings.
- Do I need a public IP to use SRT?
- In most scenarios, no. Many setups use outbound connections or network tunnels that remove the need for a dedicated public IP. The exact configuration depends on the gear and how the Ingest is set up.
