6. Motivation
7. • Home security cameras are expensive • Surveillance services have crazy high monthly fees • Gotta have a cam on each room • IP cameras are hackable • Setup is complicated • Can’t see anything from a WAN without DDNS • OEM and 3rd party remote viewing apps are unreliable Motivation
8. • Don’t talk to other smart home/IoT hardware • Use email to notify you about stuff • Push notifications are irrelevant • No face recognition • No image classification • Can’t find your pet Motivation
9. • Dogs move from room to room or go outside • Yeah!… cats kinda move around too • You want to… give Fido a ball • Or scare your cat • Want to check if they have food or water • Want to keep an eye on the kids • Want to see if a delivery arrived Motivation

21. Tips
22. Tips • Draw, sketch or diagram your idea first • Write down a list of materials and a list of desirable features • Research about the technologies such as APIs, protocols, etc. you’ll need to achieve the desired features • Research about the parts and materials before purchasing them; pros/cons matter • Use Etcher to push Android Things image to an SD Card
23. Tips • Learn about circuits, voltages, current, etc... BEFOREHAND! • Be mindful about power requirements • Run and analyze google sample code (GitHub) • Ask questions (Google forums, Stack Overflow) • Watch how it is done (YouTube) • Try not to burn your fingers when soldering the headers (It hurts!) • Add speech to help you debugging stuff
24. TODO (Roadmap) • Face Detection And Tracking (OpenCV) • Face Recognition (TF) • Real Time Image Classification (TF) • Motion and Sound Alerts (via FCM Push Notification) • Voice Control • Indoor Mapping and Navigation using tinyLiDAR • Autonomous Patrolling
