As a result of the development of modern GSM technologies, new devices are appearing, namely compact GSM alarms, which can be used as security systems for your vehicles. Moreover, the GSM alarm can be used as a second (additional) alarm to the standard security system or as a basic security device. GSM alarms use standard SIM cards with prepaid traffic. In the event of an alarm, the alarm will send an alarm message to predefined phone numbers in the form of a voice call or SMS. Also, depending on the model, the system will provide the ability to turn on a sound siren, listen to the car’s interior, and provide “mobile positioning.”
Setting up and managing GSM alarms can be done remotely, using a mobile phone within the coverage area of cellular communications. It is worth noting that alarms are not at all difficult to install, which can be done by the car owner himself.

Signaling Applications
Private cars, motorcycles, construction and other special equipment, car rentals, etc.
Other equipment for vehicle protection and control
- GPS tracker. A GPS/GSM tracker allows you to track the location and route of a car in real time on a special Internet site. Cellular communications are used to transmit real-time location data to an Internet resource. It is best to use a tracker to control vehicles Navixy M7. At the base of the GPS tracker there are permanent magnets, which allow you to easily and securely attach the device to your car in just a few seconds.
A distinctive feature of the M7 tracker is dual-mode GPS tracking. You can choose continuous or interval mode. In the first case, the GPS tracker is constantly in touch and allows you to monitor movement online. In interval mode, the GPS tracker is in “sleep mode” most of the time, and updates location data only after a specified time interval (from one hour to several days), which ensures battery autonomy for up to 2 years.
The magnetic base of the Navixy M7 GPS tracker has a small contact button that provides control over the detachment of the device from the vehicle. As soon as the GPS tracker is removed, the device will immediately transmit the corresponding signal to the data center. In accordance with the notification settings, the data center will send you a message - via SMS, email or phone call. The message will contain the time and address of the location from which the signal was sent. This way, you will immediately know that the device has been disconnected from the monitored object.
Security equipment is a source of electromagnetic radiation (when operating in a GSM network). When installed in a vehicle, it is necessary to avoid placing security devices in close proximity to the vehicle's on-board electronic units and electrical wiring harnesses to prevent interference with their operation. When installing devices in the trunk, you must make sure that the GSM network signal level is sufficient where the car is parked. The approximate level of the GSM network can be assessed by the indication of a cell phone, but it is worth keeping in mind that the level of sensitivity of the security device may differ from the indications of a cell phone.

Calloused hands never get bored!
Every conscious owner cares about his personal property, and its protection becomes a priority. This is especially true for owners of cottages, dachas and just private houses, but a protection system in an apartment will not be superfluous. A GSM home alarm system that sends an alert to the owner will help solve this problem.
GSM security alarm systems for home
An alarm with a GSM module is a special protection system that notifies interested parties about the entry of unauthorized persons into the territory of the home. The message is transmitted via a cellular communication channel, which ensures that the owner or security point quickly receives the data. A GSM security alarm can inform the owner about:
- turning off gas and electricity;
- smoke in the room (fire protection);
- reducing the temperature in the house;
- gas or water leak.
Expensive, highly functional protection systems are capable of remotely turning on various devices to which they are connected, for example, lamps, a heater. The principle of operation of these alarms is based on the ability of various sensors that were installed in the room to detect changes, movements in the house or other phenomena. The data is immediately transmitted to the control unit, which analyzes the received information and, if necessary, sends a message to the owner via the GSM alarm module with the appropriate text.
Such messages are called “alarming” messages; they can be transmitted to the owner’s mobile phone in several ways:
- voice messages (voice communication);
- MMS or using a GPRS channel (video/audio information is present).
These protection systems may have different configurations if, for example, it is necessary not only to install sensors, but also to conduct video surveillance. The standard GSM alarm set includes the following elements:
- a control unit with a built-in GSM communication module;
- sensors of various types;
- GSM antenna (external, for better reception);
- autonomous signaling devices: spotlights, sirens, etc.;
- spare power supply (batteries/accumulator).
The most inexpensive, easy to configure and install options are those in the form of a separate unit with autonomous power supply. It contains a message transmission module, sound and/or motion sensors. Elements of the security system that detect movements can not only send a message, but also turn on the lights or siren. Sensors are usually installed in places where there is the highest probability of intruders entering.
Autonomous GSM alarm
This type of protection is powered by special batteries and is not connected to the general power supply, which makes it difficult to disable it. As a rule, 12 or 6 volt batteries are used. The protection system has been working for at least a year for all quality manufacturers, for example, Radsel, Sapsan, Strazh. An autonomous GSM alarm system can turn on strobe flashes, sound and light signals if unauthorized entry occurs. If there is a video recorder in the system, the offense is recorded.
This type of GSM alarm is controlled by a special remote control with a keyboard and connected to the panel. When choosing such a protection system, you need to consider the following points:
- Pros. A video camera will help identify the criminal, and sound and light signals will attract the attention of the owner and neighbors.
- Cons. When used separately, it has low functionality, so it is recommended to install it together with lasers on the site or other additional means of protection.
Wireless GSM alarm system for home
The main element of this complex is a sensor that is capable of recording changes in the environment. When something occurs that is regarded as dangerous, the device activates an alarm and transmits a message to the owner. A wireless GSM home alarm system turns on a siren, light, and the communication module sends SMS to a programmed number.
The complete set of the system can be different; it is possible to order a turnkey installation along with a camera, fire alarm, and sound recording. The cost will be higher, but the owner will be able to immediately receive a video on the phone showing the intruder. You can see what is happening in your home simply by sending SMS. This system has the following advantages and disadvantages:
- Pros. Easy installation; no additional installation of communications is required. The complex can be supplemented with additional sensors to expand the range of tracking and recording. The setup is simple, you can control the system using messages.
- Cons. The GSM sending module works only in the operator's coverage area. The performance of the protection depends on the range of signal transmission between the detector and the control device. This problem can be dealt with using a radio signal amplifier.
Wired GSM alarm system for home
Communication between elements in this case occurs not using a radio signal, but wires. This creates some difficulties if construction has already been completed. Laying the wires will take longer and will require repair work (in some cases). A wired GSM home alarm system works on the same principle: the sensor records changes and sends a signal to the remote control, then the system notifies the owner about the incident via SMS. Advantages and disadvantages of this option:
- Pros. High security, object reliability, prompt response.
- Cons. The kit contains wires that need to be hidden in the walls, so installation must be carried out during the construction phase. For a beginner, the installation process will be difficult.
Installation of GSM alarm
Each kit always comes with instructions that describe the installation principle, but it is recommended to involve specialized employees for this work. This guarantees the correct configuration of the protection system and the connection of all elements of the complex. If you read the description incorrectly and connect the sensors incorrectly, the protection simply will not work at the right time. Installation of GSM alarm occurs as follows:
- The territory is being studied and installation locations are being identified.
- The client signs an agreed agreement with the service, which is responsible for the safety of the property and home.
- Specialists synchronize the control panel and sensors.
- Numbers that will be notified of all events are entered into the control block.
- A control panel is installed in a hidden place in the house.
- Next, wireless sensors are installed.
- A siren and alarm lamp are mounted on the facade and connected to the panel.
- The correct operation of the sensors is checked and adjustments are made if necessary.
- The owner of the house will receive a control panel and instructions for using the alarm.
Review of GSM alarms for home
The rating of models of such protective systems is conditional, because the complexes are suitable for different purposes. Some are more successfully used in garages and industrial premises, others have proven themselves in cottages and summer cottages. Review of GSM alarms that have received good reviews from private home owners:
- Dacha 01. This is the abbreviated name of the GSM MMS TAVR model. This is a simple, inexpensive solution to protect against intruders. The system has been operating offline for about a year. This protection is used at temperatures ranging from -20 to +60 degrees Celsius.
- Dacha 02. An improved version of the above-described GSM alarm model.
- Guardian S200 MMS. Another popular model among summer residents. It is considered the best option for a country house; it is powered from the mains, but when the lights are turned off, it can work in autonomous mode for up to 12 hours.
- Express. The alarm system is well suited for small buildings and garages. Autonomous operation of the system is 6 months. The device is small and can be supplemented with other sensors.
Selecting a GSM alarm
Security service specialists will help you choose the best security system for your property. It will be difficult for an inexperienced person to do this on their own. The choice of GSM alarm system to buy should be based on the following points:
- Good protection doesn't come cheap.
- Consider the signal transmission power.
- It is better to buy an option with the ability to supplement the complex.
- Additional system functions will be a plus.
- Does the price correspond to the quality?
- Consider where this protection will be applied.
- How the body is made.

Car safety has always been a pressing issue for its owner. They tried to ensure the safety of the vehicle by any means possible. Various mechanical locks for the steering wheel, pedals, etc. were used. Secret toggle switches were installed that turned off the power to the on-board network. Later, all kinds of “squeakers” appeared.
Operating principle of GPS and GSM alarm
The rapid development of technological progress has not spared the issue of vehicle safety. And if a few years ago satellite alarm systems were available only to military or government agencies, today in almost any car store you can freely choose a GPS/GSM car alarm that is suitable for the price and functionality.
How does GPS/GSM car alarm work?
An electronic unit is installed in the car interior, which includes a microcontroller, a GPS module and a GSM module. The GPS module provides communication with the global positioning system, which determines the coordinates of the location and speed of the vehicle. The gsm module provides communication with the owner of the vehicle and the operator of the security console (if the system is connected to the control panel of the security company). The microcontroller processes the information received from the sensor system and, based on it, includes an action algorithm corresponding to the protection program.
The GPS/GSM car alarm system ensures constant communication between the car and its owner. Being far from the car, you can get information about its location or technical condition, as well as start or stop the engine. The car is controlled and its condition is monitored via SMS messages, voice calls (dtmf), as well as through the web interface of a special website.
The site is an Internet portal that receives information from a car equipped with an alarm system automatically. From the same portal, the system takes the settings for driving the vehicle. To remotely use a web portal, you only need to have any device with Internet access – a computer, laptop, iPhone, smartphone.
Alarm calls or SMS messages can be sent to several mobile phones recorded in the memory of the alarm control unit.
If the car is stolen or impounded, its location can be determined using the function. Almost any satellite car alarm kit has the ability to connect video cameras, which allows you to remotely conduct covert video surveillance of the car’s interior. Digital relays provide additional protection. If an attacker detects and disables the alarm unit, digital relays and all main power circuits. It will no longer be possible to activate them, even if you supply power directly. In addition, these same relays will block the doors with special pins.
Most modern satellite signaling devices support eCall / ERA-Glonass technologies. A car equipped with such a device can independently call the rescue service. This function is very relevant in case of an accident, if the driver and passengers themselves are not able to do anything. According to experts, the installation of such devices will reduce the consequences of injuries in road accidents by 14 percent.
General structure of the gps/gsm car alarm system
To obtain data about the current state of the car, the alarm controller is connected to the diagnostic connector or directly to actuators and sensors - tachometer, generator, injectors, speed sensors, oil pressure, etc.
To connect video cameras, a special interface is provided in the central alarm unit. Data from the cameras is sent to the system’s website and to the car owner’s mobile phone in the form of an mms message.
The controller is connected to the actuators and sensors of the vehicle
With all its advantages and high technology, the gps/gsm alarm system is not without its disadvantages. Attackers also keep up with progress; the latest equipment (scanners, code grabbers, repeaters, jammers) sometimes allows hijackers to bypass the electronic security system.

Ways to hack satellite signaling and protection methods
The weak point of the gps/gsm alarm is the communication channel with the server and the owner’s mobile phone. Attackers have several ways to disrupt this connection:
a) GSM signal jamming
The signal to a mobile phone can be jammed
— Such a simple device, costing about $120, can jam all 3G/GSM/CDMA modems within a radius of five to twenty meters.
b) SIM card counterfeiting (cloning)
The number used by the alarm has a copy in the hands of the hijackers. If the alarm is silenced using the jammer described above, the second number will be accessible and will not sound an alarm. If the alarm is checked by periodic dialing, then the dialing will be sent to a copy of the SIM card and will not cause an alarm.To protect against signal jamming and counterfeit SIM cards, the Jamming Detection function was developed. It is designed to detect attempts to jam the signal. When such an attempt is detected, the alarm locks the car, turns on the siren and records information in its memory that it was turned off. When the connection is restored, this information is sent to the server and to the owner’s phone.
V) Replacing a telecom operator's station
The device posing as a cellular operator's station is placed in a small suitcase. The car alarm GSM modem will not be able to determine which of the available base stations is real and which is fake. In case of hacking, it will not send an alarm through the real channel.
G) Localization of the alarm installation site with subsequent shutdown or disabling
The field detector, which costs $43, allows you to find installation sites for radio transmitters operating at frequencies from 1 MHz to 2.6 GHz. The device display shows the signal level and frequency of the transmitter.
In case the installation site is detected using a field detector and the alarm is physically deactivated, it is recommended to use additional GPS/GSM beacons. Such a beacon consists of a GPS receiver, a GSM modem and a battery. The device is miniature in size and can be easily hidden in hidden places in the car. The beacon is difficult to detect visually and almost impossible to detect using a field detector, since it is always in a state of sleep, only occasionally waking up to register on the network and send its coordinates to the server. In the event of a car theft, the signals from the beacons can easily determine its coordinates.
To protect against all the above hacking methods, a method of monitoring the communication channel was developed. The modem of the signaling unit communicates with the server at certain intervals - for example, sends data via http. If the modem does not connect to the next communication session, the server raises an alarm - it calls or sends an SMS to the owner of the vehicle. Of course, this method is not a panacea in all cases - somewhere there may simply be an area of poor signal reception - but, nevertheless, it significantly increases the level of vehicle safety.
Satellite gps/gsm car alarm undoubtedly has great advantages. Even if the car was stolen, it will allow you to track its coordinates. It will be much easier to apprehend the hijackers. However, to increase vehicle safety, experts recommend using satellite alarms in combination with simple and reliable mechanical anti-theft devices.
GPS. The issue of property protection has recently become a priority issue for all owners of any property.
In this regard, various types of alarms, including GPS alarms, are gaining increasing popularity in the security systems market.
These security devices have a number of advantages over others due to their unique properties. To decide whether an alarm system with a GPS module is needed as a security system, you should consider a number of its inherent features.
What is GPS Alarm?
The role of any alarm is to give a sound, light or other signal when an unauthorized person attempts to take possession of property, movable or immovable.
There are several types of alarms:
- normal, sound or light,
- alarm system with GSM module,
- alarm system with GPS module.
In this case, the effect of a conventional alarm is limited only to giving an alarm signal by an audible siren and flashing lights. If there is a wired connection with a security console or police post, an alarm signal is also sent to such a post.
They are more effective against unauthorized access attempts. This type of alarm sends an alarm to the mobile device over the GSM wireless network used for cellular communications, thereby significantly reducing response time. Naturally, such an alarm is much more effective than its classical counterparts.
The most modern type of security systems is an alarm with a built-in GPS module. Its effectiveness is greatly enhanced by the use of satellite technologies, which can be accessed through an Internet connection.
The functionality of this type of alarm system includes the ability to generate an alarm signal and wirelessly report intrusion. In fact, it has all the advantages of GSM signaling.
But, in addition, thanks to the GPS module installed in the system, which has a connection with satellites, it is possible to monitor the movement of an object. It goes without saying that this type of alarm is most appropriate to use for protecting movable property, such as a car.
What can a GPS alarm do?
As already noted, GPS alarms are most often used to protect cars. It is for this purpose that a large number of functions have been developed in alarms of this type. One of them is remote control of vehicle systems.This includes the ability to turn off the ignition or fuel supply, or block the engine. Such functions are useful not only for preventing the consequences of theft, but also for monitoring leased vehicles.
Moreover, although it is possible to stop a vehicle at any distance, this is done in such a way as to prevent a traffic accident. Thanks to a tracking system using GPS coordinates, you can find out the exact location of the vehicle at any time.
The question often arises: is it possible to use a GPS alarm for your home? This question can be answered if we take into account its specific features. The fact is that GPS is a satellite detection system. It tracks changes in GPS module coordinates in real time.
In other words, such an alarm monitors the movement of an object. This means that using this alarm system to protect stationary objects, such as a house, is inappropriate.
It's a completely different matter when it comes to household property or pets. A GPS module attached to particularly valuable property will always let you know where this item is located. The same can be said about pets. A keychain with a GPS module on the collar of a dog of a rare and valuable breed will not allow it to get lost even in the densest forest and the largest metropolis.
It is especially worth noting the role of the GPS module in monitoring children and the elderly. To always know where your child is and to have peace of mind for your elderly relative, you can use a wrist bracelet with a GPS module. All movements of this person will be displayed on the map of a kind of GPS navigator.
How to choose a GPS alarm?
To choose the right GPS alarm, you need to understand exactly what functions are needed in this case, in addition to GPS functions.It is known that each manufacturer equips each alarm model of its own production with a certain set of functions. And not all of these functions are necessary for a specific user. However, they can significantly influence the price of the product. So, let's look at the main functions.
Key fob code: static or dynamic? The key fob code is a radio signal that is sent by the alarm key fob to the receiver when arming and disarming. It can be static, i.e. unchanging, and dynamic, i.e. change each time the system is armed.
It is clear that finding a dynamic code is a much more difficult task for a thief, but the cost of the system also increases significantly. Here, when choosing, you should focus on the value of the equipment and your own wallet.
Another important function is engine blocking. Typically, the engine lock is activated when the system is armed. But sometimes it happens that the security system is equipped with a function to block the engine without arming. In this case, it plays the role of an immobilizer - a powerful anti-theft agent.
Arming in this case is also carried out using an encrypted radio signal sent from the key fob. In GPS alarms, such a signal can also be sent from other devices. This type of car alarm is always equipped with an immobilizer.
GPS alarm sensors
The difference between alarm models also lies in the set of sensors included in them. The more sensors, the greater the functionality of the security system.Alarms can be equipped with the following sensors:
- motion sensor – reacts to the displacement of the protected object in space.
- Shock sensor – self-explanatory, reacts to impact.
- opening sensor – reacts to the opening of doors, trunk, etc.
- dual-zone sensor – the coverage area is divided into two zones. The first zone - if there is a slight impact on the protected object, a short sound signal is activated. The second zone – in case of strong impact, a full alert is activated.
This article should help you decide on the choice of security systems based on their features. GSM alarms, as a rule, are installed on real estate, while the scope of GPS alarms is expanded to include moving objects precisely due to the movement tracking function.
Otherwise, all security systems have a standard set of functions, which may vary depending on the company and model. The user decides whether to install a system that has a particular function.
The determining factor when choosing a security system is the financial condition and value of the protected equipment. It should be noted that having or on a car, according to statistics, significantly reduces the risk of unauthorized access to property.
And GPS alarms ensure the quick return of stolen property, even if, against all odds, the attacker managed to overcome the security properties of the system. Therefore, if you need to protect your car and its cost justifies investing in a GPS alarm system, then its use is not a whim, but a necessity.
