1.3 Intended Audience and Reading Suggestions This SRS is useful for developer, user, external guide and internal guide.Each of them can easily understand how to use our software product by reading this SRS.

1.4 Project Scope:  

The scope of this project is what is suggested by the instructor in the project initiation document provided in the website. The document addresses the general purposes for home security system. Any detail requirements can be verified with the user or the customer. 7

HOME SECURITY FOR I-PHONE APPLICATION

2. Overall Description: 2.1Product Perspective: 

 

iPhone Technology and Literature Review application for Home security &monitoring. User can control – arm(lock)/disarm(unlock)/alarm(emergency) his home from the mobile. He can view the history of the events and camera attached in his home. Whoever can interact with our home security systems such as the lightening system, phone system, alarm etc in enable mode.

2.2 Product Features:  Reports sent in seconds via pop up messages in phone call. 

It does support WI-FI and GPRS for iphone and Internet connection for Application server.  Arm/Disarm alarm via internet keypad  Remote programming of the system  Super fast transmission speed  Easy to install and set-up  APPLICATIONS:  Alarm signal reporting  Open/Close signal reporting - Monitor by user code  Latch-key reporting  Polling loss notification - Monitor if you lose communication  Supervisory by zone - Monitor a liquor or gun cabinet in your home

2.3 User Characteristics:  Passwords:  Many users, security specialists and administrators rely at least in part on passwords to authenticate the identity of those wishing to gain access to a security system.  Passwords need to incorporate more than just letters for the greatest security, making use of numbers and other symbols available on the keyboard.  Those wishing to gain access by defeating the password security system may try commonly used passwords, or to hack the password system in order to gain unauthorized entry.

8

HOME SECURITY FOR I-PHONE APPLICATION  Biometrics:  Biometric devices detect the identity of the person trying to gain access to a security system.  In home security system, biometric scans a user's fingerprint to authenticate the person's identity before allowing the user access to the system.  Certificates:  Third-party digital security companies (called certification authorities) issue digital certificates to companies or individuals.  Digital certificates vary in their complexity, depending on the security needs of the individual or company.  The certification authority issues a certificate that the user embeds on security sysytem. When the user attempts to gain access to secured areas on a network, or even secured websites, another software program at the receiving end of the request validates the required digital certificate.  Smart cards:  An authorized individual may use a smart card to authenticate his identity in order to gain access to secured devices or areas.  Smart cards look much like a credit card and have a microchip and memory embedded in the card.  The user inserts a smart card into a reader device and enters a password. A remote server checks the smart card against the entered password.  If the user enters incorrect passwords too many times in a row, the reader device can be programmed to destroy the smart card to eliminate unauthorized access.  If a user loses his smart card, a network administrator can turn the card off so it can no longer be use to gain access to secured devices or areas.  types of user required for Server machine:  database services The user passes the sql requests as a messge to the database server,the result of each sql command is returned to the same database server.  communication services: when security alarm is in enable mode then the user passes the request as a calls or messages to the apple device.

HOME SECURITY FOR I-PHONE APPLICATION

2.4Operating Environment: In our system we would be using following software and hardware:  Softwares: 1. Objective c: • Objective-C's features often allow for flexible, and often easy, solutions to programming issues. •

Delegating methods to other objects and remote invocation can be easily implemented using categories and message forwarding.

•

Swizzling is a pointer allows for classes to change at runtime. Typically used for debugging where freed objects are swizzled into zombie objects whose only purpose is to report an error when someone calls them.Swizzling was also used in Enterprise Objects Framework to create database faults. Swizzling is used today by Apple’s Foundation Framework to implement Key-Value Observing.

•

Serialization, commonly called Archiving in Objective-C, can be done by overwriting read and write methods.

2. SQL server(2005/2008)  SQL Server 2005 (codename Yukon), released in October 2005, is the successor to SQL Server 2000.  It included native support for managing XML data, in addition to relational data. For this purpose, it defined an xml data type that could be used either as a data type in database columns or as literals in queries.  XML columns can be associated with XSD schemas; XML data being stored is verified against the schema. XML is converted to an internal binary data type before being stored in the database.  Specialized indexing methods were made available for XML data. XML data is queried using XQuery; Common Language Runtime (CLR) integration was a main feature with this edition, enabling one to write SQL code as Managed Code by the CLR. 10

HOME SECURITY FOR I-PHONE APPLICATION 

SQL Server 2005 introduced "MARS" (Multiple Active Results Sets), a method of allowing usage of database connections for multiple purposes.



The next version of SQL Server, SQL Server 2008, was released (RTM) on August 6, 2008 and aims to make data managementselftuning, self organizing, and self maintaining with the development of SQL Server Always On technologies, to provide near-zero downtime.



SQL Server 2008 also includes support for structured and semistructured data, including digital media formats for pictures, audio, video and other multimedia data. In current versions, such multimedia data can be stored as BLOBs (binary large objects), but they are generic bitstreams.



SQL Server 2008 also natively supports hierarchical data

3. SQL light: • A high-level overview of what SQLite is and why you might be interested in using it. • This document describes situations where SQLite is an appropriate database engine to use versus situations where a client/server database engine might be a better choice. • This document enumerates and describes some of the features of SQLite that make it different from other SQL database engines. • A list of all titled pages on this website, sorted by title. 4. Visual studio (2005/2008): • Microsoft Visual Studio is an integrated development environment (IDE) from Microsoft. • It is used to develop console and graphicaluser interface applications alongwith WindowsForms applications, web sites, web applications, and web services in both native code together with managed code for all platforms supported by Microsoft Windows, Windows Mobile, Windows CE, .NET Framework, .NET Compact Framework and Microsoft Silverlight. • This is the newly established software development environment which helps developers to develop applications quickly and gives optimum, 11

HOME SECURITY FOR I-PHONE APPLICATION efficient, scalable, performance oriented applications in different languages like Visual Basic .NET,C#,ASP.NET,XML/XSLT, HTML/XHTML, JavaScript and CSS etc. 5. Window 7(min 1gb RAM):  Features:  Internet access (fees may apply)  Home Group requires a network and PCs running Windows 7  Windows XP Mode requires an additional 1 GB of RAM and an additional 15 GB of available hard disk space.  DVD/CD authoring requires a compatible optical drive 

PCs with multi-core processors: Windows 7 was designed to work with today's multi-core processors. All 32-bit versions of Windows 7 can support up to 32 processor cores, while 64-bit versions can support up to 256 processor cores.



PCs with multiple processors (CPUs): Commercial servers, workstations, and other high-end PCs may have more than one physical processor. Windows 7 Professional, Enterprise, and Ultimate allow for two physical processors, providing the best performance on these computers. Windows 7Starter, Home Basic, and Home Premium will recognize only one physical processor.

6. Iphone SDK(x-code):  Apple today provided development details for native third-party applications for the iPhone and iPod touch.  The company has created a development kit that uses the same programming language and interface used by Apple itself and now includes Cocoa Touch, an API designed to add touchscreen input. Programmers now use a modified version of Xcode that is not only used to write programs for the iPhone but to manage them as well, including designing the visual interface, source control, and debugging.  Developers can also test the final results in an environment known as the iPhone Simulator, according to Apple.

12

HOME SECURITY FOR I-PHONE APPLICATION 

Single Window As an experienced Xcode user, the first thing you will notice about Xcode is that the many windows used to perform the development tasks you work on every day have been consolidated into a single window. The Xcode work area has several unique UI elements that make it easy to work on many different tasks, even multiple projects, without cluttering your work area. Your editor is always front and center.



Navigators The unified navigator UI provides live filtering of content and search results, so you can focus on your current task.

 Hardware: 1. Server(1 gb RAM): Application server:  A new, user-friendly Add Roles Wizard that helps you choose the services and features that are necessary to run your applications  Application Server Foundation, the default installation of Application Server that includes the .NET Framework 3.0 features (If you have applications that are built with the .NET Framework 3.5, you can download and install the .NET Framework 3.5 onto the operating system.) 2. IP camera: This device takes the images and videos of different areas and sends the updates to the server as well as the device. 3. Sensor: Mechanical device sensitive to light, temperature, radiation level, or the like, that transmits a signal to measuring or control instr -ument.

2.5Design and Implementation Constraints:  Databases: 

Sql light-visual studio 2008/2010.  Visual Studio 2008 is focused on development of Windows Vista, 2007 Office system, and Web applications. For visual design, a new Windows Presentation Foundation visual designer and a new HTML/CSS editor influenced by Microsoft Expression Web are included. J# is not included.  Visual Studio 2008 requires .NET 3.5 Framework and by default configures compiled assemblies to run on .NET Framework 3.5, but it also 13

HOME SECURITY FOR I-PHONE APPLICATION supports multi-targeting which lets the developers choose which version of the .NET Framework (out of 2.0, 3.0, 3.5,Silverlight Core CLR or .NET Compact Framework) the assembly runs on.  Visual Studio 2008 also includes new code analysis tools, including the new Code Metrics tool (only in Team Edition and Team Suite Edition).  For Visual C++, Visual Studio adds a new version of Microsoft Foundation Classes (MFC 9.0) that adds support for the visual styles and UI controls introduced with Windows Vista.  Visual Studio 2010 features a new Help System replacing the MSDN Library viewer.  The Help System is no longer based on Microsoft Help 2 and does not use Microsoft Document Explorer.  Dynamic help containing links to related help topics based on where the developer was in the IDE has been removed in the shipping product, but can be added back using a download from Microsoft  The device will continuosly update the server about the latest videos, calls ,messages etc.  The user can access the data by entering the particular customer id and password on the server website.  The user can also get a back-up of data of what so ever time and date needed.

 Security considerations: 

  

security system has the ability to range from a simple motion sensor that turns on a light or an alarm to an entire suite of detectors – motion, door/window sensors, glass-break, cameras – setting off the most advanced applications employing cutting edge technology. Not only can your highly developed system activate lights and alarms, but also it has the capability of notifying the proper emergency response team. You can also program your system to notify you about an intrusion or emergency via email, cellular phone, instant message, or other online notifications. When you are trying to secure your home, a home security system can go all the way.

 language requirements:  English  communications protocols: It should be voice alert and message alert inside Home security application.  security considerations:  burglary: The system shoots an alarm in case a burglary takes place and sends an instant notification to our apple device.  Breakdown: 14

HOME SECURITY FOR I-PHONE APPLICATION In case someone intentionally tries to break the security system before barging inside the system by default sends an alarm notification to the apple device.

2.6 User Documentation: Once Development is completed, Online Help document will be created to guide users with complete Prototype. 1. iPhone users:  ip camera This device takes the images and videos of different areas and sends the updates to the server as well as the device. 

Calls and messages settings

2. Admin users operating Web Server:

 Remove unnecessary services:  operating system installations and configurations, are not secure.  Switch off all unnecessary services and disable them, so next time the server is rebooted, they are not started automatically.  Switching off unnecessary services will also give an extra boost to your server performances, by freeing some hardware resources.  Monitor and audit the server:  All the logs present in a web server, should ideally be stored in a segregated area. 

All network services logs, website access logs, database server logs (e.g. Microsoft SQL Server, MySQL, Oracle) and operating system logs should be monitored and checked frequently.

 User accounts:  Unused default user accounts created during an operating system install should be disabled. 

There is also a long list of software that when installed, user accounts are created on the operating system.



Such accounts should also be checked properly and permissions need to be changed required.

15

HOME SECURITY FOR I-PHONE APPLICATION 2.7 Assumptions and Dependencies: 

   

The project was started with the assumption that we would be given the necessary support in the form of hardware and software resources. Our project depends a lot on the inputs. User has the basic knowledge of the system environment. The users have sufficient knowledge of security system. The home security system should have the product installed correctly. Whoever can interact with our home security systems such as the lightening system, phone system, alarm etc in enable mode.

16

HOME SECURITY FOR I-PHONE APPLICATION 3.System Features: 3.1 System Feature 3.1.1 Functional Requirements: 

 

 

Sound an alarm upon detection of intrusion. An audible alarm should sound immediately upon the triggering of any currently activated sensor in the system to discourage further progress by the possible intruder. Contact law enforcement authorities. After a programmable delay period, the alarm must be able to automatically phone (or in some other way contact) local law enforcement. Contact fire department. Without delay, the system must be able to automatically phone the local fire department when smoke detectors indicate a possible fire. The remote alarm should allow for delay before contacting authorities in case of a user triggered, false, or random alarm. Contact medical emergency services. A panic button will, again without delay, automatically summon an ambulance via phone when pressed. Alert security company. The alarm will alert the security company on intrusion, fire, or emergency. In fact, the system can summon police, fire, or ambulance via a call to the security company. Once again a user-defined delay should be used.



Control and monitor all sensors. The system will be able to monitor and control all sensors currently marked as activated. Even if a sensor is not currently activated, the system should monitor the status of that sensor.



Control optional electrical appliances (lights, etc). The system will be able to toggle external electrical appliances, such as lights or an additional audible alarm to further deter intruders. This feature is necessary for vacationers as well as those who leave their home vacant from time to time.



Remote access. The user must be able to check the status of the system through a remote link

5.4 communication interface: The system uses a Wi-fi or GPRS connection to connect to the database. The code itself though, does not specifically direct the network controllers to do any work.

6.Other Nonfunctional Requirements: 6.1 Safety Requirements: 

  







if you're going to be away from home for a few days, adjust your telephone ring to its lowest volume setting. An unanswered phone may tip off a burglar that no one is home. Also, have a neighbor or friend collect your newspaper and mail. Never cancel delivery - you don't know who will get that information. Keep garage doors shut. Don't leave notes on the door for service people or family members. These alert the burglar that you are not home. If out of the home for an extended period of time, create the illusion that someone may still be there. Leave a TV or stereo on in the room where a burglar would most likely break in. Use exterior lighting and motion detectors to minimize burglar concealment. Keep your alarms working properly. Test and maintain your sensor at least once a month, or follow the manufacturer’s instructions. sensor most often fail because of missing, dead or disconnected batteries. Replace batteries at least once a year. Testing is generally as simple as pushing a button and listening to hear the beep. Practice a fire escape plan. In addition to installing fire alarms in your home, you should develop a fire-escape plan and practice it at least twice a year with all members of your household. In the event of a fire, every family member should know at least two ways out of each room.

Don’t just buy one! There’s safety in numbers. Install at least one fire alarm on each floor of the house or residence and outside all sleeping areas. Some fire-safety advocates recommend installing fire alarms inside each sleeping area if sleeping with the door closed.

6.2 Security Requirements :   



 



Keyless entry to your front door . The card is integrated to a home security system which activates entry. There is no need to fumble with cumbersome sets of keys. Infrared motion sensors. These can be a welcoming beacon of light for family and friends and a simple yet effective deterrent for intruders. Security camera. These should be installed at the front door in conjunction with a videophone that allows you to communicate and see who is outside. You can now see who is at the door without leaving the comfort of your seat. Security system keypads. These offer detection devices, audio and visual alarms with telephone diallers that alert security-monitoring stations and call any telephone or mobile number to alert you of the situation back at home. Home-safety devices. Choose a device that provides emergency lighting to ensure you and your children don’t have any accidents during a power failure. One safety switch. These are now compulsory in new homes but a smarter alternative is to use one safety switch for each circuit. Your home will not be plunged into total darkness when the power is cut due to one incident. An added feature of safety switches is extension leads that come in handy when you’re using power tools outdoors. Motion detector lidhts trouble shooting. Installing motion detector lights in the surroundings of your house is a total relief from the fear of theft, intruders, lousy animals etc. These lights not only help you see through the darkness, but come on with an alarming bang in case of hunches. On the off chance if these lights are malfunctioning, you need to troubleshoot the problems at your earliest

6.3 Software Quality Attributes: 





Interface is accessible from at least one or more convenient places. This includes all of the home's common entry ways, bedrooms, and frequently used rooms. If the system interface is not readily accessible, then it will not be as easy to control and will offer little convenience. Interface and system must be properly connected to the sensors. It is essential to have secure wiring, preferably inside the walls, for reliable sensor information to guard against false alarms and tampering. System must be connected to a device that can contact authorities. 28

HOME SECURITY FOR I-PHONE APPLICATION The system should be directly wired in to the phone lines, preferably in such a way that will not cut off phone usage from inside the house. 

System must have a backup power supply. The system needs to have a backup power supply capable of lasting at least 24 hours in order to thwart attempts to bypass the security system by tampering with the power.



Security related devices must be tamper-proof. Connections to the power supply and phone lines must be secure. The housing for the actual security system and sensors must also be secure enough to withstand tampering.
