The emergence and widespread use of wireless GSM communications led to a massive transition, first of car, and a little later of home, garage and country house security alarms, from sirens to a full-fledged remote control system for the security loop. Things especially accelerated after the reduction in communication tariffs and the reduction in the cost of GSM modules. In some cases, for example, for a garage or a summer house, it is almost impossible to build an effective alarm with the ability to instantly receive a signal about an opening.
Advantages and disadvantages of alarm systems for cottages based on a GSM module
The development of mobile communication technologies has made it possible to obtain a very compact and economical device in the form of a GSM communication module with a control unit and a sensor system. Ideally, a wireless alarm system provides the following functions:
- Notify the owners of the dacha when one of the sensors is triggered. In some models, the alarm system sends a signal with a specific code, which allows us to judge the reasons for the alarm;
- Arm, disarm and check the current state of the alarm using Push messages, listen to sounds inside the cottage;
- Control the numbers and sequence of sending SMS information about the activation of an alarm element;
- Take a photo and send the frame to the programmed address;
- Control powerful electrical appliances using commands from a mobile phone. You can turn on/off irrigation, heating, ventilation, or any of the devices connected to the power module.
For your information! The first three functions are provided to all, even the most budget alarm models with a GSM module; the presence of more complex functions is determined by the characteristics of the specific system for the dacha.
In the first alarm models, manufacturers tried to combine the functions of autonomous and wireless alarms. That is, when triggered, the system turned on the siren and sent a message to the mobile phone. But in practice it turned out that the sound often interferes with catching a thief in the country, so newer versions have a function to turn off the howler.
A dacha outside the city may be located in a “blind” zone or an area with poor GSM signal reception, so there is a certain risk of losing control of the alarm system. In some cases, an external antenna is installed, but this only encourages criminals to commit illegal actions in the country.
In addition, not all GSM modules tolerate “work” at the dacha equally well in conditions of low temperatures or extreme heat. The most vulnerable are batteries, which need to be regularly charged and insulated indoors.
The most interesting alarm models for dachas
In addition to the general functions listed above, many models have their own interesting specific features, the presence of which makes them most suitable for use in the country.
GSM alarm system “Sentry” for a summer residence
The development of the IPRO company is well known for its good quality of elaboration of the alarm logic. To the above-mentioned features of Sentinel 4, you can add several specific functions, especially suitable for use in the country:
- The ability to control several powerful electrical appliances, for example, an irrigation pump or a ventilation system.
- The function of connecting and de-energizing the power supply in the garden. This option becomes especially valuable in case of strong winds or problems with electricity in the dacha premises.
- The ability to simulate the presence of owners in the dacha premises. According to a programmed sequence, the lights in the rooms, in the courtyard or at the entrance to the room can be turned on and off.
In addition, the GSM alarm system can issue four types of text messages to a mobile phone when a certain type of security module sensor is triggered. If necessary, you can remotely turn on the microphone and listen to the situation in the cottage.
Alarm system with GSM “Dacha 01”
“TAVR Dacha”, models 01 and 02, are deservedly considered one of the leaders in the line of domestic and foreign alarm systems. And we must admit, such an assessment corresponds to the capabilities and functions of an alarm system with a GSM module.
Firstly, the most significant advantage, in comparison with other models for dachas, is the two-module layout of the “TAVR Dacha”. This means that the control unit with a processor and sensors is made in the form of a separate panel, which is necessarily located inside the dacha room. The GSM signal reception and transmission module is made in the form of a separate box with autonomous power supply, which allows you to separate both units over a distance exceeding 200 m.
In fact, this principle of the “TAVR Dacha” layout makes it possible to solve most of the problems with “shadowing” and signal jamming, which are so feared by most users of wireless alarms with a GSM module.
Secondly, setup and access to service and programmable functions is possible only with the use of special magnetic key fobs. They are also used to remove or activate the alarm system. This means that any unauthorized persons entering the dacha premises where the control panel is located, or even intruders who entered by hacking, will not be able to change the settings of the wireless alarm system with a GSM module.
Thirdly, the autonomous GSM alarm system “TAVR” Dacha is designed for very economical consumption of electricity; the average duration of operation from four finger elements, according to the manufacturer, should be at least one year. Truly economical is very important when protecting remote objects to which there is no constant and regular access.
For your information! To ensure the operation of the Sentinel, the manufacturer recommends using an acid battery.
Most sensors are located inside the control panel housing, so certain requirements must be met when installing an alarm. Do not hang the panel on a heated or supercooled surface or wall with a high level of vibration. This, first of all, negatively affects the condition of batteries and electronic components that are not designed to withstand condensation.
In addition, the GSM model “Dacha 01” and 02 allows for fairly serious current temperature control. When the air temperature in the room is more than sixty degrees, the module generates and sends a message about a critical situation.
GSM alarm system "Guardian"
If your dacha is a full-fledged country house with a significant territory and a large number of objects that could be of interest to a criminal element, you will need a more powerful and advanced alarm system.
The most correct solution would be to install additional video or photo cameras that record events in the protected area in real time. In this case, you can install a full-fledged security complex or limit yourself to installing the “Guardian” GSM alarm module.
The Guardian's capabilities significantly exceed previous models. For example, the “Guardian S200 MMS” option is capable of working simultaneously with 16 wireless motion sensors and taking up to 20 high-quality photographs. In this case, a series of images can be received on a mobile phone and the degree of threat can be determined without visiting the site.
With proper use of the camera, you can monitor the situation in a very dense area control mode. In some cases, this method allows one to identify signs of an impending threat long before it appears at the dacha. For example, to record vehicles or people of marginalized species.
Wireless alarms are well suited for most cottages, provided that there is stable power supply in the room for a full day. Otherwise, the module will bombard you with messages about an emergency situation and switch to an economical operating mode. With a complete blackout, the device will be able to operate on a standard 1000 mAh battery for no more than 8 hours.
This type of GSM signaling deserves close attention due to its high resistance to information load. Most events related to setting and disarming alarms, making changes to the program, and the emergence of threats are duplicated by the Guard microprocessor via text messages to several addresses, including emails.
You can rest assured that a GSM alarm system is worth installing on your car. But, before we begin to describe the advantages of this truly wonderful type of car alarm, I would still like to urge car owners to be vigilant. You must be aware that in its pure form, a GSM car alarm will not fulfill its function - car safety.
Reliability of GSM signaling
Especially when it comes to prestigious, expensive models that are specially ordered for theft. And they order it not from street punks, but from professional car thieves using professional equipment. Let's face it and tell ourselves what we already know - any electronic system can be hacked by an electronic system.
Therefore, reading about the currently unique capabilities of GSM car alarms, it doesn’t hurt to think about how to create a comprehensive car security system: electronics + mechanical anti-theft devices. Well, now let's move on to the car.
What is a GSM car alarm?
This is, in fact, the same computer that is designed not only to protect your car, but also to monitor its location in real time. In the event of an attack, the alarm transmits information about the violation to the owner and to the security console. Control is carried out using a mobile phone with GPRS functions. And others are probably not being released now.
The distance for control is unlimited, whether you are in a neighboring house or in Tahiti, it does not matter. In addition, the gsm system will completely secure any mechanical actions with your car, without your knowledge, such as loading a car onto a vehicle for the purpose of theft.
How does GSM alarm work?
Traditionally, the system consists of a central unit and several (optional) security sensors. The kit includes a remote control key fob and the car alarm is no different from the classic GSM car alarm except for the principle of operation. Security sensors monitor the perimeter around the car and the interior of the cabin, trunk and hood.
Classification of GSM alarms
- Price segment. T.N. “budget” - in principle, are a classic form of car alarm. The more expensive ones have all the standard equipment, plus autonomous power supply, and a GPS receiver for monitoring.
- Method of informing the owner. These are SMS notifications and auto-dialing with voice guidance. Plus combined, i.e. both types of notifications.
- The method of programming a GSM car alarm is the holy of holies. It is this that affects the quality and reliability of the system. Programming with SMS messages is still common, but is gradually becoming a thing of the past. The bulk of gsm alarms are programmed and controlled by a DTMF signal (tone dialing via voice menu)
- Method of powering the system. Usually this is a 12V source. More advanced systems have an autonomous power system, which turns on in case of force majeure. Almost all GSM car alarms are equipped with a function to notify the owner about a power problem.
Without a doubt, gsm alarm systems today have no equal in mass use. Thanks to the use of modern technologies, it not only performs security functions, but also greatly facilitates the functionality of the car and the comfort of operation for the car owner.
- Gsm alarm can act as a listening device inside a car
- In addition to tracking the location using a GPS module, the system monitors the speed and fuel level, and conducts video surveillance.
- With certain settings of the tilt/motion sensors, the alarm will warn the owner about an attempt to remove the wheels or load the car onto the platform.
- Remote control allows you to remotely start the engine for warming up. Those. All the delights that were previously installed separately are now in the hands of a GSM car alarm system.
With all the positive characteristics, of course, there is also a certain negative. In particular, GSM signaling is very dependent on the electronic signals existing in the city and interference in the form of reinforced concrete structures.
However, today GSM alarm system is the most optimal option for ensuring the safety of your car, both in price and in its properties and capabilities.
Good luck, car lovers.

The high cost of a vehicle attracts a large number of car thieves. Therefore, the next task after purchasing a car will be to ensure its safety. GSM car alarm is a new word in ensuring vehicle safety. The device is capable of transmitting the coordinates of the vehicle's location. The user will also have the opportunity to listen to all the sounds occurring inside the car.
What is GSM alarm
A modern security system is a functional device that performs various functions. GSM/GPS car alarm transmits information about the location and possible threats to the vehicle owner. The system is also capable of transmitting alarm data directly to the security company's console.
One of the main advantages of the system is its operating range. No matter where your car is, your phone will always receive information about its condition. In addition, the system responds to threats both inside and outside the cabin. When attempting to load a car onto another vehicle, the owner will immediately receive information about this.
The principle of operation of the GSM system
GSM car alarm system is a system consisting of a main module, as well as a set of various sensors, for example. Their main functions:
- transfer of data to the owner about the location of the car. Using GPS systems, coordinates are determined with an accuracy of up to 100 meters;
- control of the vehicle engine and the ability to block it;
- transmitting a sound signal from the car interior.
At the owner's request, additional sensors can be installed in the car.
The indicated functions of GPS/GSM alarm are its main advantages. A conventional alarm system cannot boast of them. As in traditional alarm systems, the process of controlling GSM security can be carried out using a key fob. The owner can control its operation, which prevents the possibility of reprogramming the GSM system to another control panel.
Classification
On the market, consumers can come across various types of GSM systems. One of the classifications of modules is based on the method of transmitting information to the owner. The signal can come in the form of an SMS message or a phone call. There are also combined systems on the market that use both notification methods.
Car alarms with GPS/GSM functions are divided into expensive and budget models. In more expensive options, the owner receives not only a security system kit, but also a source of autonomous energy for the device, as well as a transmitter with which the car can be controlled remotely.
Car alarms are also divided according to the method of power supply. The majority of devices are connected to the car’s on-board network, but there are models that also work with batteries. Such models have a function to notify the owner about the charge status of the device’s battery. 
Advantages of GSM security alarm
One of the main advantages of the system is signal transmission and the ability to remotely control a vehicle over a long distance. The system operates anywhere on the planet, is capable of transmitting all information about the condition of the vehicle, and thanks to the use of a GPS sensor, the function of determining the coordinates of the vehicle is available.
The variety of functions is another advantage of this system. You can not only control the car and find out about its condition, but also listen to what is happening now in the vehicle. The entire control process is simple and is carried out using a phone or remote control. By receiving messages about the condition and location of the object, the owner can also find out about such parameters as the remaining gasoline, speed, and direction of movement of the car. Installing additional equipment, for example, motion sensors that respond to tilt, will also allow you to receive information about loading a car with a tow truck or removing wheels. 
Another advantage of this device is the ability to control the operation of the machine’s engine. The owner can either start or stop the engine, or block its operation. And all this can be done remotely, being at any distance from the car.
The GPS/GSM security alarm system is reliable and cannot be hacked using third-party devices. The presence of a battery in such devices allows you to control transport if the main battery is missing.
Alarm selection
When choosing a system from several models, you need to focus not only on cost, but also on the manufacturer. It is desirable that the device have the following functions:
- protection against false alarms;
- control of car locks and its engine;
- self-diagnosis, monitoring the condition of all system elements;
- the presence of a battery, which will allow the system to operate autonomously.
When choosing, remember the rule: the more functions, the better. In terms of installation complexity, this type of system is no different from a conventional alarm system. Getting to grips with the controls is also not difficult. The kit includes detailed instructions describing all functions and features.
One of the important elements in a car alarm with GPS/GSM functions is a mobile phone. You can use any model of device, and it does not have to be touch-sensitive. Of course, the advantage of using a smartphone is getting a map with the location of the car. All that is needed in a phone is the availability of call and SMS functions. It is worth remembering the following:
- the phone number must be linked to your GSM system;
- the device must be in full working order;
- The mobile device must always be within range of the network.
Before you start using your phone with a security module, study the features of your mobile operator. Pay attention to the quality of communication and the cost of SMS messages. As a rule, for a month of using a GSM/GSM system you will spend a small part of the money.
Popular GSM alarm models
The market offers consumers various device options at different prices and functionality. The main advice from professionals is to purchase models with a large number of functions from manufacturers that have proven themselves in the market. It is advisable that the seller offers you the service of installing and configuring a new system. So, what popular models does the market offer?
Top 5 popular GSM alarm models
If you are thinking about purchasing such a device to protect your car, don’t delay it. The number of additional features, as well as the price of the device, are directly related - the more additions, the higher the cost of the device. Therefore, you should first pay attention to exactly what functions you plan to use. This will allow you to find a model with the optimal price-feature ratio.
GSM security systems designed to ensure the safety of the home during the absence of the owner of the premises. Their main advantage is ease of installation and wireless connectivity. Modern solutions boast wide functionality and a large number of applications. Today, alarm sets are most often used to protect the perimeter from illegal entry, fire monitoring, gas leaks, as well as notification of excess air temperature. External sensors constantly read environmental indicators and transmit them to the main module. The GSM security system processes the data, after which it decides on the need to inform the owner through alarms about the occurrence of an emergency situation. Thanks to this, you will always be aware of the situation in a private house or apartment. You will not only be able to receive information from sensors, but also configure the operation of existing equipment in real time. To do this, it is recommended to choose complexes with the function of remote control of household appliances or a boiler, which will help heat the house before arrival, turn on the interior lighting or air conditioning.
GSM security alarm systems
The rapid development of technological progress is increasingly replacing the familiar security systems that use wired connections of elements. They are being replaced by products capable of transmitting a signal via radio channels. And this is no coincidence, because GSM security alarm systems are not only much more convenient for subsequent operation, but also do not require cable laying. Sensors located at a certain distance transmit a signal to the control device, after which the wireless alarm informs the owner about the occurrence of an emergency situation. It is also worth noting that they operate both from the network and from an autonomous power source.
Selecting a wireless security system
This question is asked by almost everyone who is faced with the question of choosing a wireless or wired alarm system. There is nothing complicated here, because most modern kits are fully compatible and support work within a single security complex. When purchasing, it is recommended to pay attention to the following parameters:
- The first is the same signal transmission frequency between the devices and the module. The most common models are with frequencies from 900 to 1800 MHz. Therefore, you should focus on this range. If you do not take this factor into account, you risk getting a GSM security alarm system that is not capable of joint operation.
- The second thing to look at is the maximum possible distance between the head unit and the sensors. At the same time, if you are going to use wireless equipment in your home or country house, then this indicator may not be particularly important, while for a larger facility it will play a decisive role.
