Map and Cameras

KestrelOS shows a map with devices, POIs, live sessions (Share live), and ATAK/iTAK positions. Click markers or use Cameras page to view streams.

Map Layers

• Devices - Fixed feeds (IPTV, ALPR, CCTV, NVR, etc.) added via API
• ALPR (OSM / DeFlock) - Crowdsourced license-plate cameras from OpenStreetMap; toggle on the map (camera icon control). Reference only, no stream.
• POIs - Points of interest (admin/leader can edit)
• Live sessions - Mobile devices streaming via Share live
• CoT (ATAK/iTAK) - Amber markers for connected TAK devices (position only)

Cameras

A camera is either:

1. A device - Fixed feed with stream URL
2. A live session - Mobile device streaming via Share live

View via map markers or Cameras page (sidebar).

Device Types

device_type	Use case
alpr, nvr, doorbell, feed, traffic, ip, drone	Labeling/filtering

source_type: mjpeg (MJPEG over HTTP) or hls (HLS .m3u8 playlist)

Stream URLs must be http:// or https://.

API: Devices

Create: POST /api/devices (admin/leader)

{
  "name": "Main gate ALPR",
  "device_type": "alpr",
  "lat": 37.7749,
  "lng": -122.4194,
  "stream_url": "https://alpr.example.com/stream.m3u8",
  "source_type": "hls"
}

List: GET /api/devices
Update: PATCH /api/devices/:id
Delete: DELETE /api/devices/:id

Cameras endpoint: GET /api/cameras returns devices + live sessions + CoT entities.

ALPR layer (DeFlock / OpenStreetMap)

deflock.me has no bulk download API. KestrelOS queries OpenStreetMap via Overpass (surveillance:type=ALPR) and returns GeoJSON FeatureCollection from GET /api/alpr.

• Map: ALPR layer is on by default (toggle top-left to hide). Marker popups show OSM identifying tags (manufacturer, model, operator, ref, Wikidata, etc.) when contributors tagged them.
• Offline: Run npm run import:alpr to preload SQLite; cache serves automatically when Overpass is unreachable.

POIs

Admins/leaders add/edit from POI page (sidebar). POIs appear as map pins (reference only, no stream).
