The amazing development and brilliant success of the GSM cell system worldwide directly relates to its proven and reliable technology and its worldwide roaming ability, enabling more than 5 billion people worldwide to be connected anytime and almost anywhere.
While the voice and SMS and more recently the Web applications have been and remain the most common used by the majority of private subscribers, a professional market for the same technology is rapidly growing and finds usage in a variety of fields such as Telemetry, Health Care, Automotive & Tracking, Payment, Security & Remote Control.
In the Security & Control Applications, GSM communication modules installed in security and control systems enable over the air communication between these systems and any GSM mobile phone and so to 1) remotely monitor the security of a house or an office from a mobile phone and 2) remotely control home / office electrical appliances from a mobile phone.
The competitive advantage of GSM based security and control systems lies in the wireless connectivity of the solution, as alarms are reported over the air and not over a regular telephone line that can easily be cut. Furthermore the GSM based communication allows to be informed on and to control from any GSM mobile phone, hence without any additional investment required, turning it into a very cost efficient and “Do it Yourself” solution.
SMS / MMS messages or calls are sent by the GSM Alarm and Control System to pre-defined numbers in case of burglary and similarly SMS / MMS messages or calls are sent from any mobile phone to the GSM Alarm and Control System to remotely switch on or off appliances such as lights, heating, sprinklers…
Most of GSM Alarm and Control Systems available on the market consist out of a central unit including the GSM communication module, to which several kind of detectors are connected, either through wires or wirelessly. The most common detectors are infrared movement detectors, smoke- gas- and fire detectors, door opening detectors, glass-break detectors. Furthermore internal and external sirens as well as relays for the remote control of appliances can be connected.
In conclusion, GSM based security and control systems offer an easy to handle, do it yourself and Low cost solution for anyone willing to secure and control houses / offices without contracting expensive security companies and purchasing expensive remote control infrastructure.
