Summary

In this chapter, we learned how to build a modular security system based on Raspberry Pi Zero. There are of course many ways to improve this project. For example, you can simply add more modules to the project, like having more motion sensors that triggers the same alarm. You can also use some simple software like Ngrok to access the live video stream remotely, even if you are outside of the WiFi network of your home.

In the next chapter, we are going to dive into the Internet of Things again, and learn how to monitor and control your home from anywhere in the world!
