The main factor constraining the development and implementation of GSM-signaling is ignorance of the population (both natural persons and organizations) not only capabilities of these devices to be integrated into almost any sphere of activity, but also that such devices even exist. Another problem is that not every GSM-alarm system is able to quickly and easily be integrated into the equipment listed above systems, become a part of it. Source: Kai-Fu Lee. To do this, not only have good abutting the hardware component is important as the flexibility and versatility of software code. So way, GSM-alarm system that has these basic features, is able to create a simple self-contained system of remote control, and complex integrated complex. Experience shows that in this currently on the market all with great interest and demand is a simple (smallest), and easily integrated GSM-alarm system, because in addition to a low enough price on their basis can build exactly the system that maximally satisfy the requirements and objectives of the customer, not overpaying for this for redundancy and uselessness of a complete set. Thus, by creating a simple, versatile and affordable GSM-alarm system, it will be possible on the principle of modularity (“designer”) to create integrated solutions model, which will eliminate the gap between the previously expensive and complex, “smart home” and clients. That transition from complicated and expensive systems to simpler and affordable will expand the scope of the GSM-alarm domestic production.
