IPCam Orange Pi Dashboard (Updated)

1. Overview

IPCam Orange Pi Dashboard is a lightweight web-based surveillance system built on top of MediaMTX.

The system is designed for:

Orange Pi (low-resource hardware)
Multiple IP cameras (4–10 cams)
No AI processing (unlike Frigate)
Full control via MediaMTX Control API

2. Architecture

Components

IP Cameras (RTSP - H264 recommended)
MediaMTX (stream proxy + recorder + API)
Dashboard Backend (scheduler + API)
Dashboard Frontend (live view + playback UI)

Data Flow

Camera → MediaMTX → WebRTC → Dashboard
Camera → MediaMTX → Recording (fMP4) → Storage → Playback UI

3. Core Features

3.1 Live View

Grid layout (1 / 4 / 9 cameras)
WebRTC streaming (low latency)
Auto reconnect
Lazy loading streams

3.2 Playback

List recordings by:
- Camera
- Date
Play fMP4 files via HTML5 video
File-based playback (no timeline initially)

3.3 Camera Management

Add/remove camera (update MediaMTX config)
Reload MediaMTX if needed

3.4 Recording Schedule (IMPORTANT)

Configure recording time per system:
- Weekdays: 18:00 → 08:00
- Weekend: 24h
Implemented in Dashboard (NOT MediaMTX)

4. MediaMTX Integration

4.1 Endpoints

RTSP: rtsp://:8554/
WebRTC: http://:8889
API: http://:9997

4.2 Control API Usage

Enable API

api: true
apiAddress: :9997

4.3 Toggle Recording via API

Enable recording

POST /v3/config/paths/patch
{
  "paths": {
    "cam1": { "record": true }
  }
}

Disable recording

POST /v3/config/paths/patch
{
  "paths": {
    "cam1": { "record": false }
  }
}

4.4 Bulk Update

{
  "paths": {
    "cam1": { "record": true },
    "cam2": { "record": true },
    "cam3": { "record": true },
    "cam4": { "record": true }
  }
}

5. Scheduler Design

Logic

Dashboard backend controls recording
Runs every 60 seconds

Example Logic

if weekend:
    record = true
else:
    record = (hour >= 18 or hour < 8)

Implementation

setInterval / cron job in backend
Calls MediaMTX API

6. Storage

Format

fMP4 segments

Path

/recordings/<camera>/<timestamp>.fmp4

Notes

Files created per segment (e.g., 5 minutes)
Recording starts immediately when enabled

7. Technology Stack

Backend

Node.js (Express) or Python (FastAPI)
Responsibilities:
- Scheduler
- MediaMTX API integration
- Recording index API

Frontend

HTML + JS (or React)
WebRTC player
Video playback UI

8. Performance Requirements

4–5 simultaneous streams
Minimal CPU usage (no transcoding)
Stable on Orange Pi

9. Constraints

Browser requires H264 (NOT H265)
WebRTC requires UDP port (8189) open
Firewall must allow:
- 8554 (RTSP)
- 8889 (WebRTC HTTP)
- 8189/UDP (ICE)

10. Future Enhancements

Timeline playback (merge segments)
Multi-user authentication
Mobile UI
Event-based recording (optional)

11. Summary

MediaMTX handles streaming + recording
Dashboard handles logic + scheduling
Recording is controlled via API (not config reload)

This architecture is optimized for simplicity, performance, and scalability on Orange Pi.
