How it works?
The principle of GSM alarm system operation: protected area is equipped with all necessary sensors and control panel with the GSM module. Interaction between the sensors and control panel is being provided through the radio channel (433MHz/315MHz/868MHz). In case of invasion of unauthorized person into the controlled territory one of the sensors triggers, the radio channel passes this information to the GSM module that activates and passes the alarm messages or calls to CMS (Central Monitoring Station) or mobile phones of responsible for the protection of property person and to the property owner.
The main functional objective of such alarm systems is to determine the fact of malicious entry to protected be the system area and to notify the owner with the help of disturbing phone calls to a mobile phone and/or sending the messages. Such GSM alarm systems are pretty universal and they can also be used for the protection of country houses, apartments, retail kiosks, shops, offices and other properties. When the alarm system is in an enabled mode if one of the sensors discovers emergency, the controller automatically calls to the specified cell phones numbers and sends alarm messages. Also in some cases you can listen to the secured area through the built-in microphone. It is very beneficial and sometimes it is the only acceptable way to use the GSM alarm system at objects where it is difficult to strip cable and telephone networks.
