What is a Raspberry Pi camera?

The Raspberry Pi Camera is a specialized camera module designed for Raspberry Pi boards, allowing users to capture images and record videos. Whether you’re building a smart surveillance system, a DIY webcam, or an AI-powered vision project, the Raspberry Pi Camera offers flexibility and high-quality imaging at an affordable price.

Raspberry Pi camera explained

A Raspberry Pi Camera Module is an add-on accessory that connects to a Raspberry Pi board via the CSI (Camera Serial Interface) port. This module enables the Raspberry Pi to capture photos and videos, making it perfect for:

• Photography and video recording

• Computer vision & AI applications

• Security and Surveillance systems

• Live streaming & time-lapse photography

Key features of a Raspberry Pi camera

Compact & lightweight – Small enough for embedded projects.
High-quality imaging – Up to 12MP resolution on the latest models.
Infrared (IR) versions available – Ideal for low-light and night vision.
Compatible with Python & OpenCV – Supports advanced image processing.

How to use a Raspberry Pi camera

Step 1: Connect the Camera Module

• Locate the CSI port on your Raspberry Pi board.
• Insert the camera ribbon cable (blue side facing Ethernet port).

Step 2: Enable the Camera

• Open a terminal and run:

sudo raspi-config

• Navigate to Interfacing Options > Camera and enable it.

Step 3: Capture Images & Videos

• Take a picture:

raspistill -o image.jpg

• Record a video:

raspivid -o video.h264 -t 10000

• (Records a 10-second video.)

Step 4: Advanced Camera Applications

• Use Python with OpenCV for image recognition and AI projects.
• Stream video live over the internet for surveillance.
• Create time-lapse photography for creative projects.
