ProjectIntroduction

General Problem StatementModern homes and office have many needs for securityA 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

General Project RequirementsGOAL: 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.

General Solution StatementSoftware 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

General Solution StatementHardware 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

ProjectSpecifications

Operating EnvironmentSoftwarePlatform independentClient computer must support modern web

browsers (internet explorer 6.0, firefox 1.5)HardwareHost computer must have a serial port to

initially configure the microcontrollerCamera Module must be able to withstand

moderate vibration and seasonal temperature and humidity changes

Intended UsersPerson 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 UsesTo remotely monitor a room or area.

AssumptionsDevice shall be easy to install, configure, and useUser is familiar with operating a computerUser will have a computer with a serial port and a network with continuous internet access. Home environment will comply with the specified operating environment

LimitationsThe 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 remotelyDevice response time is limited by the speed of the user’s Internet connection and the amount of connected users

Market: security conscience home and business owners

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.

Lessons LearnedWhat went well Communication Teamwork

What didn’t go well Project Integration was difficult Camera Problems – ( loses last data packet )

Technical knowledge gainednetwork microcontroller capabilities

Non-Technical knowledge gained Time management

What to change Start Earlier

Problem and Problem Management

Anticipated ProblemsWriting java code Integrating microcontroller with camera

Unanticipated ProblemsTeam schedulingFinding partsCamera problems

Closing SummaryWeb 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.
