Raspberry Pi Surveillance System Without Continue Internet

gemini generated

A self-contained Raspberry Pi surveillance system that:

1. Runs autonomously (like EyeOS) — camera always active and streaming.
2. Keeps searching for a known Wi-Fi hotspot (your phone).
3. Starts streaming automatically when the phone hotspot is available.
4. Lets you view the camera feed on your phone (via browser or app).

Here’s a detailed, production-ready setup:

⚙️ Step 1: Setup Raspberry Pi Camera & Software

1. Enable the camera

sudo raspi-config

• Go to Interface Options → Camera → Enable
• Reboot:

sudo reboot

2. Install dependencies

sudo apt update
sudo apt install python3-picamera2 python3-flask git -y

📸 Step 2: Create a Local Flask Streaming App

Create file /home/pi/camera_stream.py:

from flask import Flask, Response
from picamera2 import Picamera2
import time

app = Flask(__name__)
piCam = Picamera2()
piCam.configure(piCam.create_preview_configuration(main={"size": (640, 480)}))…
