USB Webcams generally have inferior quality to the camera modules that connect to the CSI interface. They can also not be controlled using the raspistill and rasivid commands in the terminal neither by the picamera recording package in Python. Nevertheless, there may be reasons why you want to connect a USB camera to your Raspberry Pi, such as because of the benefit that it is much easier to set up multiple camera’s with a single Raspberry Pi (see below).

A number of solutions exist to connect to the USB camera with Python. Unfortunately the picamera software does not work with USB webcams. I suggest to use OpenCV. To help install OpenCV, follow my guide here. Now to record a single image:

You can connect as many webcams as you want as long as they are powered up per their requirements, such as using a powered USB hub. Each usb web cam that you connect gets listed under /dev/video where n, starting at 0 for camera 1, is the id of the device.

You can control a USB webcam both using bash in the terminal and with Python. First plugin the camera and see if the Raspberry Pi recognises it by entering lsusb in the terminal. It should show something like this:
