Introduction
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
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.
General Solution Statement
Software

Programmed in C


Programmed in HTML


Program to test camera module
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 Statement
Hardware

Networked Microcontroller


Configure Tini Operating System and enabled http server
Install web server and custom camera software and web
application.
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
Project
Specifications
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

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.
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
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

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.
