The Wi-Fi remote security camera project is based around the Arduino Yùn board. The Arduino Yùn is a powerful Arduino board with integrated Wi-Fi and an onboard Linux machine based on a very small Linux distribution called OpenWrt. It also has a USB port so that you can connect hard drives, cameras, or other USB devices. We will use all these features in this project.

The following is an image of the board that was used in this project:

You will also need a USB camera to stream live video with the Yùn. You can basically get any camera that is compatible with USB Video Class (UVC). For this project, I used a Logitech C270 HD camera.

If you plan to use the camera for other applications, such as recording still pictures on the Yùn, you will also need a microSD card to save the data. Finally, you will need a micro USB cable to power the Yùn. The following is a list of all hardware components that are required for this chapter:
