Manager

System-level services: CoreManager (plugin-to-plugin RPC, FFmpeg, signed requests), DeviceManager (cameras, discovered cameras), DownloadManager (one-shot download tokens).

camera_ui_sdk.manager

CoreManagerEvent

Bases: TypedDict

Core manager event payload.

Emitted when a core system event occurs (e.g. cloud account changes, remote-server availability, plugin lifecycle changes). Subscribe via coreManager.onEvent to react to system-level state changes.

type instance-attribute

type: str

Event type identifier (e.g. cloudAccountChanged).

data instance-attribute

data: Any

Event-specific data payload. Shape depends on the event type.

CoreManager

Bases: Protocol

Core manager interface for system-level operations.

Provides access to cross-cutting services like the FFmpeg binary path, server addresses, HMAC signing for cloud requests, inter-plugin lookup, and a stream of core system events.

Accessed via api.coreManager in plugins.

Example
ffmpeg_path = await api.coreManager.getFFmpegPath()
addresses = await api.coreManager.getServerAddresses()


def on_event(e):
    if e["type"] == "cloudAccountChanged":
        print("Cloud account state:", e["data"])


api.coreManager.onEvent.subscribe(on_event)

onEvent property

onEvent: Observable[CoreManagerEvent]

Observable for core manager events (e.g. cloud account changes).

Example
api.coreManager.onEvent.subscribe(lambda e: print(e["type"], e["data"]))

Plugin interface name (e.g., 'ClipDetection')

required

Returns:

List of plugin info dicts with id, name, contract

DeviceManager

Bases: Protocol

Device manager interface for camera operations. Provides methods to get cameras and push discovered cameras.

Accessed via api.deviceManager in plugins.

Example
# Get a camera by ID or name
camera = await api.deviceManager.getCamera("Front Door")

# Push discovered cameras (for cloud-based discovery)
discovered = await fetch_cameras_from_cloud()
await api.deviceManager.pushDiscoveredCameras(discovered)

pushDiscoveredCameras async

pushDiscoveredCameras(cameras: list[DiscoveredCamera]) -> None

Push discovered cameras to the backend. Use this when cameras are discovered asynchronously (e.g., after cloud login). Cameras will be immediately visible in the UI for adoption.

Parameters:

Name Type Description Default
cameras list[DiscoveredCamera]

List of discovered cameras to push

required

getCamera async

getCamera(cameraIdOrName: str) -> CameraDevice | None

Get a camera by ID or name.

Parameters:

Name Type Description Default
cameraIdOrName str

Camera ID or name

required

Returns:

Type Description
CameraDevice | None

Camera device or None if not found

DiscoveredCamera

Bases: TypedDict

Discovered camera from a discovery provider.

Represents a camera found during network scanning or cloud lookup that can be adopted into the system. Push these via deviceManager.pushDiscoveredCameras so the user can pick them in the UI without waiting for the next discovery poll.

id instance-attribute

id: str

Unique, stable identifier for this discovered camera (used for deduplication).

name instance-attribute

name: str

Display name shown in the UI adoption list.

manufacturer instance-attribute

manufacturer: NotRequired[str]

Camera manufacturer label (optional).

model instance-attribute

model: NotRequired[str]

Camera model label (optional).

CreateDownloadOptions

Bases: TypedDict

Options for creating a download.

filePath instance-attribute

filePath: str

Absolute path to the file on disk.

filename instance-attribute

filename: NotRequired[str]

Filename for Content-Disposition header.

mimeType instance-attribute

mimeType: NotRequired[str]

MIME type for Content-Type header.

ttlMs instance-attribute

ttlMs: NotRequired[int]

Time-to-live in milliseconds.

cleanup instance-attribute

cleanup: NotRequired[Literal['never', 'on-expiry', 'on-download']]

When the file on disk is deleted (registry always expires at TTL).

  • never (default): file persists; caller manages it.
  • on-expiry: deleted at TTL. Can be fetched N times during the window — correct mode for notification images that fan out to multiple devices/recipients.
  • on-download: deleted after first successful download OR on TTL, whichever first. One-shot mode for things like backup exports.

CreateStreamDownloadOptions

Bases: CreateDownloadOptions

Options for creating a streaming download (progressive file tailing).

markerPath instance-attribute

markerPath: str

Path to a marker file that signals export is still in progress.

DownloadToken

Bases: TypedDict

Token returned after registering a download.

token instance-attribute

token: str

Unique download token.

url instance-attribute

url: str

In-app, same-origin URL: /api/download/<token>. Use for callers already authenticated against this server.

publicUrl instance-attribute

publicUrl: str

Externally-reachable, session-less URL the server publishes for out-of-band fetchers (push-notification image attachments, FCM / APNs payloads, share recipients). Shape: <externalUrl>/api/download/<token> — the token in the URL is the auth. Empty string when the server has no external URL configured (LAN-only deployments); fall back to url for in-app callers.

expiresAt instance-attribute

expiresAt: int

Unix timestamp (ms) when the token expires.

DownloadManager

Bases: Protocol

Download manager interface for token-based file downloads.

Allows plugins to register files for HTTP download via a token URL. No JWT authentication is needed — the token itself is the auth.

Accessed via api.downloadManager in plugins.

Example
result = await api.downloadManager.createDownload(
    {
        "filePath": "/tmp/export.mp4",
        "filename": "recording.mp4",
        "mimeType": "video/mp4",
        "ttlMs": 600000,
        "cleanup": "on-download",
    }
)
token, url = result["token"], result["url"]

createDownload async

createDownload(options: CreateDownloadOptions) -> DownloadToken

Register a file for download and get a token-based URL.

Parameters:

Name Type Description Default
options CreateDownloadOptions

Download options

required

Returns:

Type Description
DownloadToken

Token, URL, and expiry information

createStreamDownload async

createStreamDownload(options: CreateStreamDownloadOptions) -> DownloadToken

Register a streaming file for progressive download.

Parameters:

Token, URL, and expiry information

deleteDownload async

deleteDownload(token: str) -> None

Remove a download token and optionally delete the file.

Parameters:

Name Type Description Default
token str

The download token to remove

required

NotificationManager

Bases: Protocol

Notification manager interface for publishing notifications into the host.

Plugins call publish to ask the host to fan a Notification out to every installed Notifier-plugin and the in-app UI. The host applies user settings (master toggle, per-source toggle, quiet hours) and the publishing plugin's declared capabilities; calls from plugins without :attr:PluginCapability.PublishNotifications are silently dropped.

Accessed via api.notificationManager in plugins.

Example
await api.notificationManager.publish(
    {
        "title": "Camera offline",
        "body": "Front Door stopped recording",
        "severity": Severity.Warn,
        "deepLink": "/cameras/front-door",
        "data": {"cameraId": "front-door"},
    }
)

publish async

publish(notification: Notification) -> None

Send a notification to the host for fan-out to every installed Notifier-plugin and the in-app UI.

Resolves once the publish was handed to the transport. Downstream delivery is async and failures there never propagate back here.

Parameters:

Name Type Description Default
notification Notification

Notification payload to publish.

required
