Problem

A need exists to monitor homes while away at various locations.

Devices that address this are expensive and difficult to install, making them inaccessible to the majority of potential users.

Solution

iSecurity:Camera & WiFi device configured through iPhone application

• Notifications sent directly to the iPhone• Device requires home wireless internet connection• Minimal user interaction required for setup

Practical Design Constraints

Economic

• IZON - Close competitor [1]‒ $130 price point, similar feature set‒ Includes audio

• iSecurity‒ $99 price point‒ $49.99 manufacturing cost‒ Competitive with ability to profit

Sustainability

• Device relies on external server‒ Product Takes Off

Load problems Need to be scalable and extensible for new

products

‒ Product fails / Business Fails Server still needs to be maintained, possibly

downgraded Continued support for existing products, possibly

with degraded performance

Technical Design Constraints

Image Processing Performance

• Frame Analyzation in under 75ms‒ Comparison between frames‒ Storage‒ Transmission

Wireless Standards

• Basic requirements for Wi-Fi module‒ WEP, WPA Personal, and WPA2 Personal‒ Ad-hoc mode available for configuration

Storage• Removable SD Card

‒ Adequate size and speed

Power• 120V AC to 5V DC

‒ Must provide at least 700mA

Range

• Motion detectable at 40 feet‒ Algorithm should be adjustable by the consumer

System Overview

Testing & Debugging

Distance Testing

Approx. 40 Ft.

Unit Testing of Python Functions

• Used to isolate functionality for more thorough testing

Wireshark

NetCat

Prototype

Prototype: iSecurity Device• Connect to iPhone over TCP via ad-hoc wifi.• Get network credentials• Connect to iSecurity Server• Connect directly to iPhone via UDP hole-punching.• Upload images via custom protocol

Prototype: iPhone

Home Screen First image successfully transmitted

Prototype: iPhone

It just works

• Secure login• Images streamed

directly from camera to iPhone

• Significantly reduced server traffic

• Custom UDP protocol for streaming images

Prototype: iPhone

• Apple Push Notification Service [2]

Prototype: iPhone

Future Tasks

• Research and Purchase New Camera

• Faster Image Processing

• Local Network Functionality

• Professionally Package the Device

• Motion Detection Rage Adjustable through iPhone

• Finish iPhone UI

First Semester Timeline
