It may surprise you to learn that a Raspberry Pi can be used to stream live videos. This feature can be great for adding security to your home, as you can use this webcam as a security system.

How To Build A Raspberry Pi USB Camera [A Beginner's Guide]

This ability is thanks to a USB webcam, which can easily be connected to a Raspberry Pi. As you can imagine, this webcam can be incredibly useful.

The process of using your Raspberry Pi to build a USB camera is surprisingly simple. With the help of this informative guide, even beginners can make this useful device. So let’s get into it!

How To Build A Raspberry Pi USB Camera [A Beginner’s Guide]


Before you can proceed with this activity, you will need the following items:

  • A Raspberry Pi: though this may be obvious, it’s nonetheless important to note that a Raspberry Pi is essential to this task. To improve the performance of this camera system, it’s best to use a modern model.
  • A USB webcam: this is what you will use to create your USB camera. A Raspberry Pi Camera Module, especially if you primarily wish to take photos. Ideally, your camera should be of good quality.
  • An ethernet cable: though a wifi connection should suffice, an ethernet cable will provide a stronger connection to the internet.
  • A micro SD card: this tiny memory card is a useful piece of kit for your Raspberry Pi.

There are also a few optional pieces of kit, though these four items are the only things that you will definitely need to create a Raspberry Pi USB computer.


To set up your system, all you have to do is:

  1. First things first, you must install Raspbian OS, which is a handy operating system. If you are familiar with the world of Raspberry Pi, you may already have installed this system. 
  2. Place the SD card into the microSD card slot. This is found on the bottom side of the Raspberry Pi.
  3. Next, attach the camera to one of the various USB ports on your Raspberry Pi. It doesn’t matter which one you choose!
  4. Using an ethernet cable, attach your Raspberry Pi to the internet. To forge this connection, you must locate the ethernet port on your Raspberry Pi device.
  5. Open the PuTTY emulator application. Connect your Raspberry Pi to this application by typing in its IP address.
  6. Update the Raspberry Pi. Generally, it’s always a good idea to update your device before creating a system as it will ensure that you are using up-to-date features.
  7. Install Motion. This handy package is able to process images, making it essential for cameras and webcams. Command your device to install this package.
  8. Once the installation is finished, it’s a good idea to test that the Raspberry Pi is working with your camera. The command “lsusb” will let you see if your camera has been picked up, as you should see your camera’s name. If not, you may need to tinker with the system or try a different USB camera.
  9. Run the following command to ensure that Motion activates when you power up your Raspberry Pi: sudo systemctl enable motion. Save your progress.
  10. To turn on the camera, use this command: sudo systemctl start motion.
  11. Enjoy using your simple Raspberry Pi USB camera. If you are using it as a security system, position your camera so that it’s in a good spot. Otherwise, there’s little point in using it.

What Are The Advantages And Disadvantages Of A Raspberry Pi USB Camera?

As with all Raspberry Pi systems, there are both pros and cons to this camera system. To help you decide whether this system is right for you, here are its advantages and disadvantages:


  • This system is simple to set up. It’s particularly straightforward for people with prior Raspberry Pi experience.
  • The Raspberry Pi USB camera system is incredibly versatile. For instance, you can use it for streaming or surveillance.
  • This computer system is portable, meaning that you can take it wherever you want (so long as you have an ethernet connection). This makes it a flexible surveillance system.
  • The image quality will be solid.


  • You should bear in mind that a webcam will have a poorer quality image than a traditional camera. So if you want a superior-quality camera, we recommend using a standard USB camera instead of a webcam.
  • The coding required to activate the Raspberry Pi camera may be rather tricky, especially if you are a beginner.
