Home Security is the most important requirement in modern world. According to (Security System, 2010) has been discussed impotency of the security system and available modern technology to safeguard your home and family. Moreover security systems may capable of providing emergency service at the first time of the problem occurs and also it is capable of detecting motions, flood, gas and fire before, you are even aware.
This topic is not a new invention because there are many products around the world that used for the security of houses. There are some product only using a security camera, another product that is only using motion detection and reporting and another project is combining all motion detection, camera system, alert system, etc. Touch Screen Wireless GSM Home Alarm Systems with Auto-Dialler / SMS Alert (TY1109-G1E) is described according to (Made in China.com, 2011), in product there is 1 wireless infrared detector, 2 sensors for door and window, siren, keypad and control unit. So this product type, is Home Alarm which is having 500 productions per day and they have target of some export market as follows North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, Mid East, Eastern Asia, Western Europe. There is a nice looking key pad, compatible with GSM networks for reports alarm event via SMS and calling. This system allows up to 6 phone numbers including 2 numbers for management and 4 numbers for personals, the system capable of set dialling sequence according to actual needs. The Home Alarm system supports up to 15 wireless zones and each zone can have up to 4 sensors and also 1 dedicated zone for remotes also having the capable of extend that 8 wired zones. Another feature is having facility to listen record up to a 10 second voice message in the host and able to hear via phone when answering alarm calls. System is capable of reporting the sensor name via SMS when detection is completed.
Another home security providing company is available at the www.alarm.com. They have provided the many security facilities to protect home and business. Web and mobile control are enabled with security system. This security system not only protecting the home and business, it can adjust up to protecting the children and other important things in your house. This system capable of getting notification about the kids when they get back from school what time of your teen came last night and This security system has a value to get instant notification when a medicine cabinet, gun cabinet, liquor cabinet or the other dangerous things are opened anonymously. Then another facility is, get notifications about the housecleaners arrival and how long they stayed. You can also get notification about your teenagers whether they are doing the homework in basement or upstairs and whether they are playing video games. That type of service is not only protecting the house, it`s protecting your family. Other than these facilities it allows to get the notification about the flood at time to prevent the damage. Further security system will provide notification if your garage is open longer than it’s required. They have provided the facility to customize the security application according to requirements of the customer. In the automation facility you can set your security system as follows Lights on when you disarm the system, automatically turn down the thermostat, Lock the doors in an emergency and Lights On, when front door is open .So customer can easily select the proper and required facility as he/she needs. Further they have provided the remote control facility via phone and web. This system will interact with iphone, android, blackberry and web enable cell phone to turn on/off lights, set automated light schedule, set automated thermostat schedule and set motion trigger recordings, likewise there are so many facilities given to the customer(Alarm.com, 2011).
This is another system that developed for home security. It is manufactured by china and imported to Orbyx Electronics in Canada. This system is totally wireless system which is called HWS100 Wireless Home Protection System. You will be able to know the security status of your home at all the time by using this high quality security system which is having user-friendly features. The HWS100 main panel is used to manage the security system, which collects security information from wireless sensors around the home. In HWS100 will be alerted via lights and sounds when detect the security breach. According to the specification will be provided HWS100 main panel, remote system controller, door/window sensor, Motion sensor, AC power adapter for main panel, double side adhesive for door/window sensor, screws and screw anchors, mounting bracket for motion sensor, mounting template and user guide along with the system. So customer can easily setup the security system but it only performing alert only lights and sound. Then it can only control via remote controller. There is no way to monitor home via camera or control the lights via mobile phone (Orbyx Electronics, 2009).
Home security and controlling system which is designed for using electronics and web interface is used to control and monitor the system. Microchips have been used to achieve the goals of the project. To reduce the complexity of electronic has been used special development board called PICDEM.net 2 Development Board. This electronic equipment is capable of TCP/IP communication; most common Microchip ENC28J60 is used to Ethernet controller. This electronic board has eight LED’s that have the ability to control by user. LED 0 is indicating the status.LED and blinks off and on to show that board software is indeed running. Then LED 7 is used as a mirror status of the relay that drives the lamp. When the lamp is on, so is LED7 is on and vice versa. Another advantage is, it does indicate if lamp is burned out. This project has used special type of sensor, called nominal closed sensor to get the status about doors and windows (Dolloff, 2008).
This also a surveillance system for home security which is capable of SMS/MMS and also another advantage is this system is capable of self initiated service to the house holder. This system mainly based on sensors and web camera input to the developed computer program. A function of the system will detect any intruder to home premises via web cam and sensors. Then computer programme is sending an alert message to user’s mobile phone. When it detects the motion, the computer system is programmed to inform its user with the snapshot of that detected intruder. The user can analyze the received snapshot and he/she can plan out the next step. (Singh, Gupta and Bishnoi, 2011)
Parallel port is used for widely for control electronic devisers using the computer program. So parallel port have some slandered input to computer as well as output for the electronic devisers. First of all we need to identify the parallel port and its functionality. The parallel port may have set of signal line that are could control via CPU for sends or receives data from other component as example signals can be communicated via modem, printer, keyboard, mouse, etc. In parallel port, there are two types of signals as “1” for open and “0” for close. Parallel port is capable of sending 8 bits and receive 5 bit at a time. Below picture shows the parallel port pins and how those pins are categorized. In this picture D for data pins, C for control pins, S for status pins and G for ground pins are represented.
Parallel Port - Data Ports
Data ports are D0 to D7 which is highlighted in the red colour in the above picture. These data lines will be read by the particular port address. The data port address can be found from the computer properties, in XP operating system you may find the data port from Control Panel > System > Hardware > Device Manager > Ports (COM & LPT) > Printer Port (LPT1) > Properties in Resources > Resource Setting and you can see your address for your parallel port as 0378-037F in decimal data port address is 888, it will return 8 bits of data port. When you set “0” for all data port it will be in binary as follows “00000000” when you set “1” for data port it will be in binary as “10000000” and “2” for “01000000” likewise you can set values to the data port but value 4 is representing as “00100000” and value 3 is representing as “11000000”.When considering the bit pattern for “1” it shows as “10000000”. So in data port “D0” will be set to high voltage and other “D1” to “D7” pins will be set to zero voltage. In real environment D0 belongs to 2nd pin in parallel port likewise D1 belongs to 3rd pin, and so on (Saltuklaroglu, L., 2003).
Parallel Port - Status Ports
Status ports are “S0” to “S7” which are highlighted in blue colour in above picture but it doesn’t show all the ports. Only five status line will be shown. The address of status port is 0379 this is can be calculated as "DATA+1" and physically capable of sending 5 numeric data from the 10 - 11 - 12 - 13 - 15 the pins in parallel port (Saltuklaroglu, L., 2003).
S0: - Time out controls in handling.
S1: Not used
S2: Mostly not used but sometime this pin used to cut condition (PIRQ) of the port.
S3: if nError or nFault detected by the printer, this bit become to lower voltage.
S4: In the select state, this bit becomes high voltage when the data inputs are active.
S5: This pin indicates either paper error or paper end status, becoming high voltage.
S6: This is used to send an Acknowledgement.
S7: This pin indicates busy by setting up voltage to lower value. When you are using external parallel port from PCI slot of the computer, the port address may change. So those data can be found in (Storr P., 1998.). External parallel port address is 0x278 this value is in hexadecimal when converting this value to decimal it’s become 632. Therefore we can use this address if we are using external parallel port. According to the best practice external parallel port is good because it won’t make any damage for the mother board, if we use inbuilt parallel port, there is a possibility to crash the mother board from the high voltages.
