Monitoring your USB camera for security in a network


In this section, we will create a project that allows us to monitor a USB camera that is connected to an Arduino YUN, which has a USB port and includes communication with Ethernet and Wi-Fi. So, it has many advantages. We will work on making a network between the Raspberry Pi and the Arduino YUN, so the main idea is to monitor the camera from a web page, from the Raspberry Pi. The page will be stored in the Raspberry Pi.

Configuring Arduino YUN

We will use a Logitech camera that supports the UVC protocol:

Now we will explain the steps to install our camera in the Arduino YUN:

  • Connect the board to your Wi-Fi router

  • Verify the IP address of the Arduino YUN

After we type the IP address, the following screen appears:

We will now issue a series of commands at the Command Prompt to complete the setup:

Update the package:

opkg update

Install the UVC protocol:

opkg install kmod-video-uvc

Install the camera driver:

opkg install fswebcam
