Conclusion
The Raspberry Pi is a powerful little beast and a great platform for building low-cost, but highly capable, embedded systems. The interfaces built into its GPIO connector make it easy to bolt on modules using simple low-cost electronics and a bit of configuration to create very functional and flexible systems. The inclusion of a dedicated camera interface and networking interfaces give you everything you could possible need for an Internet-connected home security system.
I've covered a lot of topics in this book, and I could have gone on and on, but I hope that what I have presented has been done in a structured and methodical way, and has given you the tools and techniques to carry on this journey so that you are able to create the perfect home security system for your needs.
