1. IntroductionThe purpose of this document is to collect, analyze and define high-level needs and features of the Safe Home System. It focuses on the capabilities needed by the stakeholders, and the target users, and why these needs exist. The details of how the Safe Home System fulfils these needs are detailed in the use-case and supplementary specifications. The document also explains the working of sensors, alarms and cameras used in Safe Home System.

1.1. PurposeThe project Safe Home System (SHS) is open source burglar alarm control and monitoring software using wireless alarm system.The is an advanced wireless Home/Business Alarm Controller which supports many types of sensors, can control various types of devices, and has computer interfaces for USB and Ethernet.With our code you can:

Arm and disarm your alarm system Read the current settings and program the device Monitor all the attached devices (PIR sensors, web cams etc)

1.2. Scope

In this system, home owner can start the system as well as independently control all the sensors through SMS or internet. Home owner will be informed by SMS and call when any human intrusion detected. He can view logs of images of human and time when intrusion took place in his home. This system will be very useful to a homeowner who does not have sufficient funds to pay for a professionally installed security system.

A majority of homeowners simply do not have sufficient funds to pay for a professionally installed security system.In addition to this; many homeowners may not feel the need to actually invest in a professionally installed security system. Many individuals who rent their homes, such as apartment owners, are usually not allowed to install permanent devices in their homes such as a professionally installed security system.Most inexpensive home security devices and components are nothing more than cheap and ineffective noise makers.

1.3. Definitions, Acronyms and Abbreviations SHS corporate web site: Users who are travelling can have full access to their home

system by connecting to the SHS corporate web site. This site routes all its communication to the CP located in the client’s home. Direct external connection to the CP is not allowed to help prevent denial-of-service attacks and other forms of hacking.

Micaz Motes: A Micaz mote is a node that has a sensor placed on it. It communicates the sensor data with the programming board via radio. The motes are loaded with nesC application program.

1.5. OverviewThe remainder of this document is two chapters, the first providing a full description of the project. It lists all the functions performed by the system. The final chapter concerns details of each of the system functions and actions in full for the software developers’ assistance.

This project deals the working of SHS using sensors, alarms and cameras. The coding is done in Java and the system communicates over wireless 802.15.4. It makes use of one PC, a GSM modem in a mobile phone, sensors, web cameras and an alarm to depict the working of the system.

The document contains the stakeholders involved, the requirements of the project, and the product features. This is followed by a future scope of improvement possible in the system.

activated

6.3 Responsiveness System responds quickly to user requests or changes in the environment. System responds within 2 seconds on average to local user requests and changes in the

environment. System responds within 4 seconds on average to remote user requests and changes in the

environment.

6.4 Capacity Maximum number of sensors, security cameras, emergency notifications, that can be

controlled by the personal computer connected via Bluetooth to the mobile for message alerts.

7. Precedence and PriorityEach user can be assigned a unique password that determines his or her level of system access. A user’s password indicates the following information: Days/hours user is authorized to use the system Which images inputs user is authorized to view and/or control Permission (yes or no) to define Quick Views and Patterns Priority levels can be assigned to each alarm and user. Priority levels enable the system to

determine which alarm or user takes precedence over other alarms and users when more than one is trying to control the same camera simultaneously.

9.2. Online Help

Online Answers of FAQ will be available Also Online help will be provided Customers can call us as well as read useful articles for more information

9.3. Installation Guides, Configuration, Read Me File

Before you even begin doing the actual physical installation you need plan out your work. What areas you need to cover by the burglar alarm system can be seen with the help of a floor plan of your home. Also adding outside landscaping and structures that could deter or help a would-be burglar to the plan is a good idea. This will help you know what needs to be where. The basic entry points of course are windows and doors.

With a hard-wired security system, you will begin with laying out the wires. This means you will need to determine the best places to drill holes into the walls and how to pull the wires through to their destination. You may even need to cut the dry wall and drill holes through the studs unless you are able to pull through the attic or basement spaces. Make sure that any holes drilled are big enough for all the wires that must run through them.

A time saver as well as work saver would be to go with a wireless system if you are able to get everything synched up. Much less work as there will be less to no drilling (depends upon how things like the keypad are mounted) and therefore less patching and clean up. You will need to decide if a wireless system is best for you or not.
