CCTV Smart Hub – Wireless

This project is an integrated security and control system built on a Raspberry Pi. It combines a camera module, motion detection, LED control, and push notifications to create a smart CCTV solution. A live video stream is provided through a web interface, and notifications are sent to your iPhone using the Pushover API when snapshots are captured or LED settings are changed.

Overview

This project continuously captures video from a Raspberry Pi camera module in 1080p resolution and downscales the frames to 720p for a live MJPEG preview in the browser. Users can:

Capture high‑resolution snapshots
Control an RGB LED (auto‑mode or manual presets)
Receive real‑time push notifications on their phone
Monitor motion detection status

Features

Continuous Video Capture at 1080p (streamed at 720p for performance)
Snapshot Capture of full‑resolution images with one click
Motion Detection using OpenCV to trigger LED and notifications
LED Control
- Auto‑mode turns LED blue on motion
- Manual presets for common colors and LED Off
Push Notifications via Pushover on key events

Hardware Requirements

Raspberry Pi (any model with Camera Module port)
Raspberry Pi Camera Module (IMX219 or similar)
Common‑anode RGB LED with resistors
Breadboard, jumper wires, and power supply
Network connectivity for streaming and notifications

LED and camera wiring on breadboard — LED and camera wiring on the breadboard.

Software Requirements

Raspberry Pi OS
Python 3
Flask
picamera2
OpenCV (cv2)
requests (for Pushover)
gpiozero (for PWM LED)
Pushover account (user key & API token)

Software setup — Software dependencies and versions.

Setup Instructions

Hardware Assembly
- Mount camera on CSI port.
- Wire LED to GPIO 17, 27, 22 with 220 Ω resistors.

Install Dependencies

sudo apt update
sudo apt install python3-pip
pip3 install flask picamera2 opencv-python requests gpiozero

Configure Pushover
Sign up at Pushover, get your keys, then edit application.py to set them.
Run the App
```
python3 application.py
```

Usage

Live Stream: MJPEG preview (720p).
Motion Status: “Motion Detected!” or “No Motion”.
Capture Image: Save 1080p JPEG + push alert.
LED Controls: Presets, “LED Off”, auto‑mode toggle.

Screenshots & Demos

Live preview — Live video preview & motion status.

Motion demo — Motion detection flips the status.

Snapshot demo — 1080p snapshot + flash override.

🎬 20‑second demo: live stream, motion flash & push notifications.
