The tutorial guides users through creating a Home Surveillance System With Node and a Raspberry Pi that can send notifications of its IP address when booting in headless mode. The system uses the Vonage API to send SMS and WhatsApp notifications, requiring a Vonage API account and a virtual phone number. The code is written in JavaScript and utilizes the Nexmo Node SDK to interact with the Vonage API. The script retrieves the Raspberry Pi's IP address and sends it as a notification via SMS or WhatsApp when run on boot-up, using a configuration file (.env) to store environment variables.
