Building a Remote Video Streaming System with Raspberry Pi and Next.js

The Journey

I built a remote video streaming system that allows me to monitor my room from anywhere using a Raspberry Pi camera module, FastAPI backend, and Next.js frontend - all tied together with Cloudflare Tunnels for secure remote access.

Technical Implementation

Hardware Setup

• Raspberry Pi 4 as the main computing unit
• Pi Camera Module for video capture
• Basic networking components

Backend Development

• FastAPI server to handle video streaming
• Python scripts for camera interfacing
• Real-time video frame processing
• Efficient HTTP streaming responses

Frontend Architecture

• Next.js application for video display
• URL rewrite configuration to proxy streams
• Responsive video player component
• Real-time feed handling

Cloud Infrastructure

• Cloudflare Tunnel for secure remote access
• Custom domain configuration
• Local HTTP to HTTPS mapping
• Zero-trust security model

Key Challenges & Solutions

1. Video Streaming Performance
