Raspberry Pi Camera setup

Introduction

The Raspberry Pi Camera lets you take pictures and videos with your Raspberry Pi. Setting it up correctly helps you start capturing images easily.

You want to take photos or record videos with your Raspberry Pi.

You are building a security camera or baby monitor project.

You want to do time-lapse photography or motion detection.

You need to capture images for a robotics or AI project.

You want to stream live video from your Raspberry Pi.

Syntax

Raspberry Pi

1. Connect the camera module to the Raspberry Pi's camera port.
2. Enable the camera interface in Raspberry Pi settings.
3. Use commands or Python code to capture images or videos.

Make sure the Raspberry Pi is powered off when connecting the camera.

Use the Raspberry Pi Configuration tool or raspi-config to enable the camera.

Examples

This enables the camera interface using the Raspberry Pi configuration tool.

Raspberry Pi

sudo raspi-config
# Navigate to Interface Options > Camera > Enable
sudo reboot

This command takes a photo and saves it as image.jpg.

Raspberry Pi

raspistill -o image.jpg

This records a 10-second video and saves it as video.h264.

Raspberry Pi

raspivid -o video.h264 -t 10000

This Python code takes a photo after showing a preview for 5 seconds.

Raspberry Pi

from picamera import PiCamera
from time import sleep

camera = PiCamera()
camera.start_preview()
sleep(5)
camera.capture('/home/pi/image.jpg')
camera.stop_preview()

Sample Program

This program uses the Raspberry Pi Camera to take a photo after a 3-second preview and saves it to the home directory.

Raspberry Pi

from picamera import PiCamera
from time import sleep

camera = PiCamera()
camera.start_preview()
sleep(3)  # Wait 3 seconds to adjust
camera.capture('/home/pi/test_photo.jpg')
camera.stop_preview()
print('Photo taken and saved as test_photo.jpg')

Important Notes

Always power off your Raspberry Pi before connecting or disconnecting the camera to avoid damage.

The camera preview may not work if you are connected via SSH without a desktop environment.

Use full file paths when saving images or videos to avoid confusion.

Summary

Connect the camera carefully to the Raspberry Pi's camera port.

Enable the camera interface using raspi-config or Raspberry Pi Configuration.

Use raspistill, raspivid, or Python code to capture photos and videos.
