How to bring a field reporter live over SRT

2 min read · Updated 22 Oct 2026

What SRT is

SRT (Secure Reliable Transport) sends live video over unpredictable networks such as mobile data. It recovers lost packets and can encrypt the stream, which is why it’s a common choice for field contribution.

Caller and listener

One side waits for the connection (the listener) and the other starts it (the caller). Usually the studio listens and the reporter’s device calls, so the reporter only needs the address, port and passphrase.

Step by step

1
Get the ingest details
Copy the SRT address, port and passphrase for this session from the studio.
2
Set up the encoder or unit
Choose SRT in caller mode and enter the details. On a bonded unit, turn on every modem or SIM you have.
3
Set the latency
More latency gives SRT more time to recover lost packets. On mobile networks, start at one to two seconds and lower it if the feed is stable.
4
Test before air
Send the feed 20 minutes early. Check picture, sound and lip-sync, and agree how the reporter hears the studio: talkback or a phone call.
5
Cut to the reporter
Add a location band and the reporter’s name, and take the feed to program.

Field checklist

Spare batteries and a power bank.
A fallback: the reporter can join from a phone or a link if the encoder fails.
An earpiece for talkback.
A signal check at the exact spot before going live.

Questions

SRT or RTMP from the field?

RTMP is simple and widely supported but struggles on lossy networks. SRT handles packet loss and supports encryption, so it’s usually the better choice from the field.
