We've now started building the software that will control our home security system by determining the format of the main configuration file. We've also installed a Web server and built a basic single-page control panel with PHP, HTML5, and CSS3, which can be accessed nicely on our mobile phone, allowing us to configure our system and view the status.

In addition, we've learned how to configure our home network and Raspberry Pi so that we can access our control panel when we're away from home.

In Chapter 9, Putting It All Together, we'll put all of the electronic elements together and write the main scripts that will run the home security system. But before that, in the next chapter, we're going to look at a few other bits and pieces, such as adding other sensors, not necessarily related to intruder detection, to our home security system. We'll also look at how we can administer our entire Raspberry Pi system remotely using a Web browser, in addition to accessing our home security control panel.
