The surveillance mode

It is cool to see the streaming from your camera, but it is much more useful to be able to run it in surveillance mode. We want the camera to react to motion and save images or videos whenever motion is detected, so that we can check them later instead of keeping an eye on the video. For this purpose, we will begin installing a motion recognition software on our Pi, which is called for apparent reasons, motion:

sudo apt-get install motion

This will install the motion software and the following command will add the necessary packages to the kernel:

sudo modprobe bcm2835-v4l2

We will even make some configuration changes to be able to access the streaming and control features that motion provides. Edit the configuration file of motion using the following command:

sudo nano /etc/motion/motion.conf

By default, the web access to motion is...
