Below we will consider the subtleties of such alarms, how they work, and which models deserve the most attention. In addition, we highlight the nuances of choice and types of modern security devices.
Distinctive features and principles of operation of GSM-alarm systems
The structure of GSM security systems is based on the interaction of tracking sensors and the central unit via a mobile network. Data transfer is provided using a SIM card of any of the operators. In simple terms, a GSM alarm is security equipment with informing the owner by phone.
The main elements of the GSM alarm system are the central unit, which, after connection, finds and interacts with all sensors installed in the house.
If any of the control elements worked (movement, glass breaking or other evidence of tampering was detected), the base receives an alarm signal and the siren goes off. At the same time, an alarm message is sent to the owner’s mobile phone.
The security equipment is programmed in such a way that the alarm goes on until the return (receive) signal is given.
The algorithm of actions of the main unit is set by the owner, and each of the zones is programmed for a specific signal. This approach allows you to accurately determine in which zone the device worked.
The GSM home alarm systems are used in various fields of activity – it is installed to protect a summer house, house, apartment, or office. The kit may include external devices that notify of the operation of the system (for example, a siren or a bell). Some elements are controlled remotely using a mobile device.
A feature of the systems is the ability to connect different types of control elements, which allows you to monitor different situations, namely the opening of windows and doors, movement, smoke, gas leakage, and so on. The principle of operation is simple and is based on opening the circuit contacts or changing (increasing, decreasing) resistance.
The main GSM signaling unit has limited functions. A specific number of sensors can be connected to it (determined by the manufacturer). That is why, when choosing a device, it is important to focus on the size of the room.
Benefits of GSM alarm
Devices for the protection of a house, apartment, or cottage, built on the principle of transmitting a GSM signal, are in great demand.
The main advantages include:
- Reliability: Information that is transmitted to the central unit is encrypted, which reduces the risk of signal interception.
- Availability of additional functions: Some models can turn on watering, start heating, activate climate control, or participate in a smart home, for example, Xiaomi Smart Home.
- Control and protection of different property:The functionality of the GSM alarm system is not limited to the protection of real estate (houses, cottages, offices, warehouses and other objects). With its help, it is easy to protect a car or other material assets.
- Easy integration:If required, connection to other systems is available, namely ventilation, lighting, unblocking emergency exits, and so on.
- Easy setup:To place, connect and set the algorithm of actions, deep knowledge is not required – just read and follow the operating instructions for the selected model. Even a beginner will be able to deal with the features of work (except for the PRO segment).
- Control of various objects:With the correct installation of sensors around the perimeter of the premises, it is possible to control company employees, the actions of a nanny or a nurse.
- Large area of action: GSM alarm coverage is limited only by mobile network coverage. To expand the area of work (typically for rural areas), it is recommended to buy and install an additional amplifier.
- Impossible to deactivate or theft:Immediately after the security system is triggered, a signal is sent to the owner at the number specified in the program. At the same time, it will not work to steal or mute the data sent to the central unit and from it to the owner. Wired devices that depend on auxiliary power have a lower level of protection.
- Possibility of connecting up to 20 and more controllers: Depending on the area of the object and the model of the product, several dozens of control elements can be connected, covering the maximum area.
- Saving power source:To extend the life of the batteries, a special (pulse) operation mode is set. This means that the security system is activated at certain time intervals (once every few seconds or minutes) to monitor the status of the protected object.
- Wide functionality:Some models have an option that allows you to send an alarm signal to several phone numbers at once. As a result, not only the owner, but also the relevant services (police, fire brigades, special security structures and other authorities) are notified about the situation.
Conclusion
Getting a security system for home is an important choice, so while choosing it make sure you understand what you need and make the purchase accordingly.
