# Teradek

> Control a Teradek encoder from your rundown — start and stop streaming and recording, capture snapshots, and react when the stream state changes.

The **Teradek** device controls [Teradek](https://teradek.com/) encoders, so the stream starts when your show does and stops when it ends — and a rule can react if the stream drops mid-show.

## Connection

Provide the encoder's **host** and **password**. **Allow self-signed certificate** covers encoders using their own certificate on the local network.

## Commands

| Command         | What it does                                           |
| --------------- | ------------------------------------------------------ |
| Start stream    | Starts a stream, defaulting to the first or active one |
| Stop stream     | Stops a stream                                         |
| Start recording | Starts recording on an encoder                         |
| Stop recording  | Stops recording                                        |
| Snapshot        | Captures a still on an encoder                         |

Units with more than one stream or encoder take an index, so a single device can drive each of them.

## Triggers

| Trigger              | Fires when                                              |
| -------------------- | ------------------------------------------------------- |
| Connection changes   | The encoder becomes reachable, or stops being reachable |
| Stream state changes | The stream starts, stops, or errors                     |

<Tip>
  The stream-state trigger is the one worth building an alert on: it fires on **error** as well as start and stop, so a rule can put a warning on a studio display the moment a stream drops rather than when someone notices.
</Tip>

## State

The device reports its connection state, model and firmware, the current stream state, the bitrate, whether it is recording, and the last error.
