Here is a mod that allows users to monitor and control webcams.
The system allows the user to set how often a picture from a webcam is sent over the network to the screen, ranging from taking a picture every second or so to several frames per second. Changing how frequently the picture updates allows the user to control bandwidth use.
The system has been built by connecting a Pi to a breadboard - a board for constructing prototype electronic circuits - which in turn is connected to a display showing the output from the webcams. You can see more footage of the Pi webcam viewer.
