Building a Home Security System with Raspberry Pi

Be a video star

Now that we know our camera module is working, we can try and capture some video. To do this, we'll use the raspivid utility. The following command will take 5 seconds of high-definition video and save the file to your Raspberry Pi:

$ raspivid –o test.h264 –t 5000
