Feeds and Commands

Feeds

A feed is a named stream of data produced by an asset. Each connector defines the feeds its assets publish — for example, a camera connector publishes a motion feed that emits an event whenever motion is detected.

Feed categories

Category	What it contains
`health`	Device status, online/offline, error states
`detection`	Motion alerts, AI object detection events
`telemetry`	GPS, attitude, battery, link metrics

Feed events

A feed event is a JSON payload with a timestamp. Events are delivered in real time over WebSocket, or you can poll the latest value via the REST API.

{
  "feed": "motion",
  "asset_id": "...",
  "timestamp": "2026-05-18T14:23:01Z",
  "payload": {
    "detected": true
  }
}

Common feeds by asset type

Camera

Feed	Category	Description
`status`	health	Online state, motion alarm, AI alarm
`motion`	detection	Motion detected event
`ai_detection`	detection	AI object detection — people, vehicles, etc.

Radio (Silvus)

Feed	Category	Description
`status`	health	Online/offline, signal strength
`link`	telemetry	Throughput, latency, packet loss

Commands

A command is an action you can send to an asset. Commands are also defined by the connector — only commands that the device actually supports are registered.

Risk levels

Level	Meaning
`low`	Reversible, no lasting effect (e.g. move PTZ, go to preset)
`medium`	Disruptive but recoverable (e.g. reboot)
`high`	Potentially irreversible (e.g. factory reset)

Sending a command

Commands are sent via the API as a task. The task payload is validated against the command’s input schema before it’s forwarded to the connector.

POST /api/assets/{asset_id}/tasks
{
  "command": "ptz_move",
  "payload": {
    "direction": "left",
    "speed": 25
  }
}

Common commands by asset type

Camera (Reolink)

Command	Description	Payload
`reboot`	Reboot the camera	—
`ptz_move`	Move the camera	`{ direction: up/down/left/right/stop, speed: 1-64 }`
`ptz_preset`	Go to a saved PTZ preset	`{ preset_id: 1 }`
`set_motion_detection`	Enable or disable motion detection	`{ enabled: true }`
