Make Data Smart Again 2018 - Building a Smart Security Camera with Raspberry Pi Zero and AWS
The document outlines the development of a smart security camera using Raspberry Pi Zero and AWS, focusing on features such as live video streaming, movement detection, and alert notifications. It discusses initial project requirements, the use of software for motion detection, and integrating AWS services for image analysis and email alerts. Key takeaways emphasize the benefits of using AI as a service for quicker deployment and considerations regarding vendor lock-in.

- 4. Project Requirements Functional • Monitoractivity in the garden. • Send warning when activity detected. • Live video stream. Non-functional • In place as soon as possible. • Low cost. • Portable. @markawest
- 5. Result : SimpleWeb Camera • Hardware based on Raspberry Pi Zero W. • Uses Motion Software to detect movement in a video stream. • Movement triggers Email Alerts containing snapshots from video feed. @markawest

- 13. The Motion Software focuseson the amount of changed pixels, and not the cause of the changed pixels! @markawest

- 15. Project Requirements Reloaded Functional •Monitor activity in the garden. • Send warning when activity detected. • Live video stream. Non-functional • In place as soon as possible. • Low cost. • Portable. @markawest
- 16. Project Requirements Reloaded Functional •Monitor activity in the garden. • Send warning when human activity detected. • Live video stream. Non-functional • In place as soon as possible. • Low cost. • Portable. @markawest
- 17. Finding an ImageAnalysis Solution OpenCV • Use Face Detection to find out if a human was in the snapshot. • Problem: What if the subject was facing away from the camera, or wearing a mask? TensorFlow • Train and use a Neural Network to find humans in the snapshot. • Problem: Potentially a fun project, but would take more time than I had available. @markawest
- 18. Amazon Rekognition • Partof Amazon Web Services suite of Cloud based services. • Image Analysis as a Service, offering a range of API’s. • Built upon Deep Neural Networks. • Launched in November 2016. @markawest

- 20. Delegating Image Processing AmazonWeb Services (AWS) Send Email Alert if snapshot contains a person Analyse snapshot from Motion Software @markawest
- 21. Why use AWSas a Data Pipeline? • Serverless. • Highly scalable. • Highly available. • Separation of concerns. • Pay as you go model, with a generous free tier. @markawest
