The market of alarm and alerting systems requires a more deterring, sophisticated and efficient solutions than the ones existed today. With the on growing car market over the years, there is a constant growth in car thefts over the world. As a result the demand for alerting systems is on a constant grow also. Nowadays, the thieves can neutralize existing system within 5 to 10 minutes, and after that no one knows that the alarm was triggered. In addition to that, the vocal alerting systems are in fact, an environmental disturbance when their alarm sounds and the vehicle owner doesn't even aware of that, if it is because he doesn't hear it, or he cannot distinguish between his alarm sound to another. In order to solve those kinds of problems and other, the next system is presented: A hardware and software integrated alarm system that can be used either for a business or a vehicle, this system also integrates a cellular communication module, this module which works on a GSM network, will send a real time alert via a SMS to any cellular phone when one of the system's sensors is triggered. This system will actually overcome the disadvantages of existing systems, as a beeper based systems, which are limited on transmitting/receiving range. Cellular based systems provide a cheaper solution comparing to satellite based systems, because it is alerting the user without any involvement of any third party, directly to cellular device of the user. Therefore, no monthly fee should be charged. The one time cost is: duplicating an existing SIM card or purchasing a new one. The regular operating cost is only when the system had established a SMS alert to the user via cellular service provider, meaning, pay per SMS. In addition the system carry the option of locating the vehicle by cellular network, this option depends on the contract between the user and the cellular service provider. The using, operating and programming of the system is very simple to the user and do not require any additional action from the user besides clicking the remote control. The programming of the system is performed only once by the system installer, the installer will feed the required data for operation, such as, sensor types that will be installed on the vehicle and the cellular phone numbers (up to 6) that will be contacted in an event of burglary. Programming is done by a very intuitive human interface, this interface based on 16-key keyboard (4X4) and a 2X16 LCD screen. Both the keyboard and the LCD are detachable from the system's body and they are no longer needed, unless a change should be made. All of these parameters are stored in the EEPROM memory of the on board micro-computer, this sort of memory is inerasable and not subjected to power failure, therefore this data will not be erased until re-programming is performed. The advantage of detaching the keyboard and the screen lays on their ratably high price, which increasing production costs, by detaching those parts, providing keyboard and screen with every system that is sold is not necessary. Only a one time supply of these parts to the installer is necessary. If the customer will insist to program the system by himself, he will be given the option to purchase his own keyboard and LCD separately. An additional advantage of detaching the keyboard and the screen from the system, is that minimizing the physical size, facilitates the concealing of the system among other vehicle components.
