What is Trio Edge?

Trio Edge is the open-source camera agent for Trio AI. It runs on your local network, discovers cameras via ONVIF, and either:

1. Relays frames to Trio Cloud for full AI analysis (memory, entity tracking, dashboards)
2. Runs AI locally with your own LLM (Claude, GPT, local Qwen) for standalone use

Core capabilities:

• Discover — Auto-find cameras on your network via ONVIF
• Relay — Push RTSP frames to Trio Cloud over HTTPS (NAT-friendly)
• Detect — YOLO v10n object detection (people, vehicles, 80 classes)
• Describe — VLM scene descriptions with any LLM (local or cloud)
• Tailscale auto-proxy — Works through Tailscale networks automatically

Quick Start

# Install
pip install 'trio-edge[mlx]'      # Apple Silicon
pip install 'trio-edge[cuda]'     # NVIDIA GPU
pip install trio-edge              # CPU-only

# Discover cameras on your network
trio discover

# Start watching a camera
trio cam --rtsp rtsp://admin:pass@192.168.1.100/stream

# Or relay to Trio Cloud
trio relay --camera rtsp://admin:pass@192.168.1.100/stream \
           --cloud https://api.trio.ai --token YOUR_TOKEN

---

Two Modes

Mode 1: Cloud Relay (Trio Cloud customers)

Trio Edge pulls RTSP or local video, registers a camera with Trio Cloud, and pushes HTTP MPEG-TS to the cloud ingest endpoint. All AI processing happens in the cloud.

trio relay --camera rtsp://admin:pass@192.168.1.100/stream \
           --cloud https://api.trio.ai \
           --token YOUR_TOKEN

What Edge does: source capture → ffmpeg MPEG-TS mux → authenticated HTTP upload What Cloud does: session management → ingest → analysis → dashboard

Mode 2: Local AI (open-source users)

Run everything locally with your own LLM. No cloud needed, no subscription.

# With local Qwen model (Apple Silicon)
trio cam --rtsp rtsp://admin:pass@192.168.1.100/stream

# With Claude API
ANTHROPIC_API_KEY=sk-xxx trio cam --rtsp rtsp://... --llm claude

# With OpenAI
OPENAI_API_KEY=sk-xxx trio cam --rtsp rtsp://... --llm gpt-4o

Note: Local mode gives you real-time detection and descriptions, but no persistent memory, entity tracking, historical analytics, or dashboard. For those features, use Trio Cloud.

Features

ONVIF Camera Discovery

trio discover
# Found 2 camera(s):
#   [1] Reolink RLC-810A (192.168.1.100)
#       RTSP: rtsp://192.168.1.100:554/h264Preview_01_main
#   [2] Hikvision DS-2CD2143 (192.168.1.101)
#       RTSP: rtsp://192.168.1.101:554/Streaming/Channels/101

Tailscale Auto-Proxy

If you use Tailscale, Trio Edge automatically detects when the macOS network extension blocks camera access and creates a transparent TCP proxy:

trio cam --rtsp rtsp://admin:pass@192.168.1.100/stream
# Tailscale detected — starting TCP proxy via system Python...
# Proxy: 127.0.0.1:15554 → 192.168.1.100:554
# (continues normally, user sees no difference)

YOLO Object Detection

Built-in YOLOv10n (ONNX, 9MB) with tiled detection for accuracy:

trio cam --rtsp rtsp://... --count
# [14:23:46] People: 3, Vehicles: 2
# [14:24:12] People: 5, Vehicles: 2 (+2 people)

API Reference

Start the local inference server:

trio serve                          # default: 0.0.0.0:8100
trio serve --port 9000              # custom port
TRIO_API_KEY=secret trio serve      # enable auth

POST /api/inference/detect

YOLO object detection.

curl -X POST http://localhost:8100/api/inference/detect \
  -H "Content-Type: application/json" \
  -d '{"image_b64": "'$(base64 -i photo.jpg)'"}'

{
  "people_count": 3, "vehicle_count": 1,
  "by_class": {"person": 3, "car": 1},
  "crops_b64": [{"class": "person", "bbox": [100, 50, 200, 300], "confidence": 0.92}],
  "elapsed_ms": 45
}

POST /api/inference/describe

VLM scene description.

curl -X POST http://localhost:8100/api/inference/describe \
  -H "Content-Type: application/json" \
  -d '{"image_b64": "'$(base64 -i photo.jpg)'", "prompt": "Describe what you see."}'

POST /api/inference/crop-describe

Combined: YOLO detects → crop → VLM describes each entity → full scene description.

from trio_edge import TrioCore, EngineConfig

engine = TrioCore()

Trio Cloud integration

When connected to Trio Cloud, Edge is just a lightweight relay:

Camera → Edge (RTSP pull + compress) → Trio Cloud (all AI in cloud)

Edge sends ~50-100 KB/s per camera. No GPU needed on the edge device.

---

Configuration

Variable	Default	Description
TRIO_MODEL	Qwen3-VL-8B-4bit	HuggingFace model ID
TRIO_YOLO_MODEL	(auto-downloaded)	Path to YOLO ONNX model
TRIO_API_KEY	(none)	Bearer token for API auth
TRIO_CLOUD_URL	(none)	Trio Cloud API URL for relay mode
TRIO_CLOUD_TOKEN	(none)	Trio Cloud auth token

See src/trio_edge/config.py for all options.

---

Troubleshooting

Problem	Solution
trio discover finds no cameras	Make sure cameras are on the same subnet. Some routers block multicast.
Camera found but can't connect	Check username/password. Try trio cam --rtsp rtsp://admin:pass@IP/stream directly.
Tailscale blocking camera access	Trio Edge auto-detects this and creates a proxy. If it doesn't work, try trio doctor.
First run slow	Model download (~2-5 GB). Subsequent runs start instantly.
Out of memory	Use a smaller model: TRIO_MODEL=mlx-community/Qwen2.5-VL-3B-Instruct-4bit

Run trio doctor to diagnose most issues.
