How Do I Record Video With a PI Camera?

If you’re looking to record video with a PI camera, there are a few things you need to know. First and foremost, you’ll need to have a Raspberry Pi computer and a compatible camera module. Once you have those in hand, it’s time to get started.

Step 1: Connect Your Camera

The first thing you’ll need to do is connect your camera module to your Raspberry Pi. Depending on the type of camera module you have, this process may vary slightly. However, most camera modules attach directly onto the Raspberry Pi’s CSI (Camera Serial Interface) port.

Step 2: Install the Required Software

Before you can start recording video, you’ll need to install some software onto your Raspberry Pi. Specifically, you’ll need to install the “picamera” Python library. This library provides a simple way to control your camera module from your Raspberry Pi.

To install the picamera library, open up a terminal window on your Raspberry Pi and enter the following command:

sudo apt-get install python-picamera

This will download and install the necessary files onto your Raspberry Pi.

Step 3: Write Your Script

Once you have the picamera library installed, it’s time to write your Python script that will actually record video. Here’s an example script that should work with most camera modules:

import picamera
import time

with picamera.PiCamera() as camera:
    # Set resolution
    camera.resolution = (640, 480)
    
    # Start recording
    camera.start_recording('video.h264')
    
    # Record for 10 seconds
    time.sleep(10)
    
    # Stop recording
    camera.stop_recording()

This script uses the “with” statement to automatically close the camera when we’re done using it. It also sets the camera resolution to 640×480 and records for 10 seconds before stopping.

Step 4: Run Your Script

Assuming you’ve saved your script as “record_video.py” in the home directory of your Raspberry Pi, you can run it by opening up a terminal window and entering the following command:

python record_video.py

This will start the script and begin recording video. The resulting video file (“video.h264”) will be saved in the same directory as your Python script.

Conclusion

Recording video with a PI camera is relatively simple, thanks to the picamera library. By connecting your camera module to your Raspberry Pi, installing the necessary software, writing a Python script, and running that script, you can quickly and easily record high-quality video right from your Raspberry Pi computer.
