MICROCONTROLLER BASED SECURITY SYSTEM USING CELLULAR TECHNOLOGY

The recent spat of daylight robberies at the jewelers has prompted us to undertake this project. This is a Research & Development project having commercial value. A typical situation in case of a daylight armed robbery is that miscreants enter the shop posing as customers, suddenly they brandish their guns and ask the shopkeepers to hand over cash and valuables. The phone lines are instantly cut and no one is allowed to leave the shop. There is absolutely no way to raise an alarm or contact the police. It is not even possible to take out a cellphone with the danger that the slightest move might invite a bullet.

In such a helpless situation, imagine that in one of the drawers there is concealed switch which when opened gives a signal to the microcontroller which in turn has a serial interface with a cellular phone which immediately dials a predecided phone number which may be a cellular phone or a ordinary landline, and the person on that phone is alerted of the robbery and not only this the voices inside the shop are also made audible. . With an addition of infrared proximity sensors even the need to open the drawer to trigger the alarm is not required and by just moving the hand near the sensor will start the security system.

The party to be alerted could be the police or some close friend or relative who can take action immediately depending on the situation. Since all the conversation inside the shop is audible so it is possible that even the escape route or the best way to counter them could be planned from the information got from the conversation.

This security system could be used not only in shops and commercial establishments but also in homes, cars etc. Imagine this system in your car. The moment it is stolen you are able to hear all the conversation inside the car. You might be able to hear the robbers saying which route to follow or in which garage they plan to hide the car.

With cellular phone costs becoming affordable and the usage tariff plans becoming economical this project has a financial viability. The best part is that since it uses cellular technology the reliability is very high. There is a chance of ordinary landline phones being out of order but cellular phones are very reliable.
