2. Presentation Outline • Introduction to Project • Project Specifications • System Implementation • Closing Materials • Demo

3. Project Introduction

4. General Problem Statement • Modern homes and office have many needs for security • A way is needed to monitor a space • Operated via a control device • Connected by Ethernet network • Remote Controlled • Controlled over the internet • Provides security, convenience, and protection

5. General Project Requirements • GOAL: Develop a web based automation system that can send images from a camera module via the WWW • Users include security-conscience home or business owners • System is designed to enable a home or business owner to securely access streamed images from a camera module located in their home or office via the web.

6. General Solution Statement • Software • Programmed in C • Program to test camera module • Programmed in HTML • Front-End Web Page used to remotely access the web server which can be run from any internet browser • Programmed in Java • Back-End Web Server that enables secure access for clients to control the camera module • Program to interface and control camera module with the network microcontroller

7. General Solution Statement • Hardware • Networked Microcontroller • Configure Tini Operating System and enabled http server • Install web server and custom camera software and web application. • Camera module • Initially test camera with commedia software. • Test camera with custom C application • Implement tini java code for camera module • RS-232 transceiver • Design and implement a serial interface between networked microcontroller and camera module

8. Project Specifications

9. Operating Environment • Software • Platform independent • Client computer must support modern web browsers (internet explorer 6.0, firefox 1.5) • Hardware • Host computer must have a serial port to initially configure the microcontroller • Camera Module must be able to withstand moderate vibration and seasonal temperature and humidity changes

10. Intended Users • Person who would like to enhance level of security for their home. • Small businesses that desire the same security/monitoring requirements that our system provides Intended Uses • To remotely monitor a room or area.

11. Assumptions • Device shall be easy to install, configure, and use • User is familiar with operating a computer • User will have a computer with a serial port and a network with continuous internet access. • Home environment will comply with the specified operating environment

12. Limitations • The number of camera modules is limited to 2 by the microcontroller interfaces. • Server must be running on the microcontroller when the client desires to connect and control remotely • Device response time is limited by the speed of the user’s Internet connection and the amount of connected users

18. Project Evaluation • Identify possible designs to implement, and choose one fully met • Hardware and software specifications fully met • Code software by specification nearly met • Design hardware fully met • Test hardware and software nearly met • Documentation fully met

19. Commercialization • Production Costs $150 • Selling price $180 • Market: security conscience home and business owners

20. Recommendations for Additional Work • Commercialization • Additional work may include a facial recognition camera. • Additional components could be a door sensor, motion detector, a house thermometer, etc.

21. Lessons Learned • What went well • Communication • Teamwork • What didn’t go well • Project Integration was difficult • Camera Problems – ( loses last data packet ) • Technical knowledge gained • network microcontroller capabilities • Non-Technical knowledge gained • Time management • What to change • Start Earlier

22. Problem and Problem Management • Anticipated Problems • Writing java code • Integrating microcontroller with camera module • Unanticipated Problems • Team scheduling • Finding parts • Camera problems

23. Closing Summary • Web Based Automation and Security • A small and inexpensive autonomous home security system is a powerful application that is viable to many markets. • This project gave our group an opportunity to work on a full cycle of a project from the first stage of development to building the final product.
