GSM automation control module is one of the most budgetary and convenient means to provide group access to the object. The GSM module is a separate device that is purchased separately and installed in addition to any gate drive or barrier. The device works like a mobile phone. A regular SIM card of any mobile operator is installed inside the GSM module. In the device memory, as in a notebook mobile phone, phone numbers of system users are added. In order to open the gate, the user calls from his phone to the number of the SIM card installed in the GSM module. As soon as the call is made, the gate opens. The Doorhan GSM module has its own housing that protects the electronics from external influences. It can be installed directly in the gate drive housing, in the barrier housing, or located elsewhere.

Specifications GSM module Doorhan

The price of the GSM-module DOORHAN: 8,700 rubles.

The issue of protecting your vehicle from theft and vandalism is always relevant. In the recent past, all possible devices (mechanical interlocks) and alarm simulators (“tweeters”) were used. Modern system protection is a more advanced product that can not only provide a high degree of security, but also allow the owner to "always keep abreast."

GSM alarm system for a car (wired, wireless) does an excellent job with both the first and the second task (it protects the car and notifies about everything).

Design features

The set of elements responsible for the possibility of using a mobile phone as a link between the gsm car alarm and the owner of the vehicle (regardless of the chosen operator and tariff) includes three main components, namely:

1. GSM module. In this case, it plays the role of a transmitting device, limited not by the cellular tariff, but by the coverage area of ​​the operator. This device ( gsm module for alarm) allows you to receive information about changes in the state of your car directly to your own mobile communication device. It can also send an alarm signal to the security console (if the security company was initially responsible for the safety of the car and the system was connected to its dispatch console). An alarm system with a gsm module can be linked to several phone numbers, which will receive SMS alerts or alarm calls (different tariffs are not a problem).
2. GSM controller. This device is designed to monitor the operation of the communication channel between the owner and his movable property, the Gsm controller is also responsible for providing information regarding the state of the system, allows you to eliminate errors in the operation of control and information SMS, and develop effective control scenarios. Their simplest variants are made on the basis of software released under the Arduino brand. It is quite possible to make simple devices on Android on your own (more on this below).
3. Digital relays. They are recognized to provide additional protection.

Accepted classification

Modern car alarms, which necessarily include a gsm module, a set of digital relays (sensors) and a gsm controller, are conditionally divided into several groups, depending on the criterion adopted as a basis, in particular:

1. Way of informing. The GSM alarm can notify the owner of the car about a theft attempt in one of three possible ways:
   • via SMS alerts(only sms notifications are received on the phone);
   • via a call (they work on the principle of auto-dial, the tariff does not matter);
   • combined option(information is conveyed to the owner simultaneously via SMS and via a call).
2. System Power Method. There are two variations on the theme, namely:
   • Gsm alarm wired(works from a source of 12 V, the interaction of the elements of the system is achieved thanks to the connecting wires);
   • gsm alarm system wireless(works due to an autonomous power source, the well-coordinated work of a security complex of this type is the result of using the properties of a stable radio signal).
3. Price range. The car enthusiast has three options:
   • economy class (alarm system with auto start and with a set of other regular modes +
     gsm controller and module);
   • middle class (alarm system with autostart, regular content and additional modes + gsm controller and module + simplest GPS system);
   • premium class (wireless multifunctional alarm system + GSM, GPS + additional features such as video surveillance).
     In addition to the above groups, GSM signaling can also be assigned to others: depending on the manufacturer (domestic firms, foreign companies- manufacturers, including Chinese, American and others) and brands (signalling Pandora, Starline, Tomahawk and others).

Top: Top 5

A variety of security products are offered to the buyer to choose from. Worthy enough. Thus, the tomahawk 9020 alarm system (detailed operating instructions, installation and programming is simple, the set of options is optimal), is good for everyone, but has one drawback: the lack of a GSM module. Fortunately, the car enthusiast has a chance to find no less attractive anti-theft protection, devoid of this flaw. Everything is available: gsm alarm system with a video camera, with the ability to control the amount of fuel in the tank and the speed of movement.

So top 5 best GSM alarms at the end of 2016:

• (made in South Korea, it is unique in that it can protect and control the condition of several cars at once, the tariff for mobile communications will not change from this fact);
• Pandora Deluxe 3700 (made in Russia, consistently ranked among the top five sellers);
• Starline B94 (made in Russia, its proprietary mobile application can be safely called one of the most intuitive interfaces);
• Pandora 500 PRO (made in Russia, another always in demand product released by Alarm-Trade based on high-tech developments);
• Magnum МН-880-03 (made in Ukraine, excellent option, with one caveat: this model does not provide a GPS module and autorun mode, but their additional installation and configuration will quickly solve the problem).

In fact, it all depends on the desires and capabilities of the car owner (what he wants: a car alarm with a camera, with or without autorun mode; what he can afford: economy, business or VIP class).

Do it yourself

Is it possible to design a gsm alarm by yourself? This event cannot be called an hourly work, but it is possible to implement the idea in a day, subject to the availability of the necessary elements (phone, toggle switch, board on the arduino platform, other components).

A board with an arduino controller, subject to an order from China, will please you with a price, by writing it out with aliexpress, you may not notice your costs at all (by the way, on the same resource you can find more budget analogs of arduino, and mobile devices that you can buy for a penny).

There is one very interesting option for consideration by a motorist, the step-by-step implementation of which is presented below. The assembly and installation of such useful functionality as a do-it-yourself Gsm alarm is quite real. The main thing is to clearly adhere to the following algorithm of actions:

1. Placement of system elements. Ideally, everything should be like this:
   • the main unit (arduino controller) and a toggle switch under the instrument panel;
   • sensors (magnets) on doors, hood, trunk;
   • the control unit (telephone) away from the radio and antenna.
2. Power off. We remove the terminals from the battery.
3. Connecting components. We connect the sensors to the controller, the controller to the phone, we cut the toggle switch into the power circuit (now, when the “to minus” is closed, this circuit will start working).
4. Binding to a phone number. We enter our phone into the phone's memory and connect the wire connecting with the main unit to the button selected as the "speed dial".
5. Connecting to the onboard network. We return the battery terminals to their original place (25 seconds after turning on the toggle switch, the car will arm, during this time you need to have time to get out of the car, such an alarm is also turned off by switching the toggle switch).

Summarizing the above...

Summing up, we can draw the following important conclusions:

1. Convenient and secure.
   GSM alarms are really convenient and reliable (it is impossible to miss alarms - the phone is always at hand, you can respond to an SMS or a call at any time - the phone is already in hand);
2. Simple and difficult.
   Just for the car owner. This is the merit of affordable installation, and a simple setup algorithm, and comfortable control, control over the system (fortunately, detailed instructions are included in the package for it).
   Difficult for an attacker. He has practically no chances for the success of the planned event (quick response, no less prompt notification of the vehicle owner, do not contribute to the fulfillment of the hijacker's plans);
3. Expensive or cheap.

The choice is up to the car enthusiast. He can become a happy owner of a ready-to-use GSM alarm system belonging to the group of one of the price categories (economy, business, premium) or prefer self-assembly protective system. It's not the price that matters, it's the end result.

What does a car owner need? Only peace of mind for the safety of your car. GSM alarm can give him confidence in the future. She is 110% doing her job!

One of the popular security systems installed on cars is the Starline GSM module, equipped with a special mobile communication module. With it, you can communicate with the security system from any phone operating in cellular communication systems according to the GSM standard. The popularity of such a solution is explained quite simply: such systems are able to maintain two-way communication between the owner and the car without interference and at a great distance, which in some cases cannot be provided by a standard alarm system.

The main advantages of GSM modules

At their core, these security systems differ from their conventional counterparts in the ability to establish communication like a regular telephone cellular connection, and it is now provided almost everywhere, which means that the distance between the car and its owner does not matter. Thus, to establish communication where the alarm key fob does not work, you can use a regular phone or smartphone.

This possibility is carried out with the help of a special module, functionally representing a cell phone with greatly reduced functions, which, however, has its own number with a registered SIM card, which is installed directly on the module, can receive and send calls, notifications and SMS, control for the status of various vehicle systems.

Functions and capabilities of GSM systems

Car alarm with a GSM module, depending on the model, allows you to perform the following actions:

• Arming and disarming using a mobile application or a simple text message;
• Starting and stopping the engine, the implementation of autorun;
• Checking the current state of the system and individual parameters of the car as a whole;
• Vehicle location in real time;
• Listening to the car interior with a microphone.

These functions are basic and in most cases, in addition to them, there are other service options. Some operations are performed using a key fob, and some specific operations are performed only using a phone. By the way, for some models, the ability to control the security alarm functions from a special web page is also added.

Adding a GSM module greatly increases security and resistance to theft - after all, in this case, it will be impossible to turn off such an alarm by cracking the code and intercepting the radio signal. In addition, in modern cars, in order to provide the ability to control and manage many functions of the car, the burglar alarm is so embedded in the onboard electrical network car and engine management system, which actually becomes part of it.

In many cases, the connection is made through standard wiring, so such alarms are, in fact, one of the most secure.

What are Starline alarms with a GSM module

In order to understand the capabilities of security systems with a GSM module, you can consider specific models.

One of the most affordable models is Starline 2CAN 35. This model is equipped with immobilizer and anti-grabber functions standard for security systems to prevent unauthorized access to the car and steal it without an owner. The GSM module provides communication with the owner's phone and allows you to learn about the most important changes in the state of the car by connecting to the CAN bus. In budget-class GSM security alarms, the module responsible for cellular communication is made in the form of a separate printed circuit board and often does not have its own housing - it is inserted into the already existing housing of the main unit.

As for the more expensive models from Starline, in this segment you can consider the D94 model with GSM and GPS modules. It also contains almost all the functions inherent in modern alarms with cellular connectivity. High resistance to hacking and theft is provided by a multi-factor system for checking and identifying the user. An individual code that changes with each arming, a built-in immobilizer and multiple locks ensure high reliability of this type of alarm.

This alarm can be controlled from a conventional key fob (in this case, the manufacturer promises a range of up to two kilometers), while the radio channel is well protected from interference thanks to a narrow-band transmitter.

Using the key fob, it is possible to remotely start and stop the engine, as well as set its automatic warm-up according to time or coolant temperature. The keychain has a peculiar shape, thanks to which it can be distinguished from the keychain, say, of the Panther alarm, the model of which can also be recognized by its shape.

Starline D94 GPS is equipped with special 3D impact and tilt sensors that can be remotely adjusted. This feature can be useful when evacuating a car from a parking lot.

feature Starline alarms is a full integration with the onboard 2CAN interface, which greatly simplifies installation, configuration and further operation. Through communication with the electronic engine control system and a common bus, the security system gains access to many of the vehicle's adjustable settings: control of various electric drives, notification of changes in various parameters and the ability to quickly change them.
And the most main function of this system- the possibility of GPS positioning, thanks to which it becomes possible to very accurately track the location of the car directly from your smartphone. In principle, cheaper and simpler systems can also do this, but geolocation is carried out using cell towers, and this is not always an accurate location, in addition, there should be quite a lot of anchor points (at least three).

One of the competitors of this system is the Sky GPS-GSM alarm with similar functionality, however, in terms of ergonomics and ease of use, it is far from Starline products. However, the price is more than attractive.

Installation Features

Installing the GSM module itself is quite simple. The main nuances depend on the specific alarm model and the car itself. There is also a big difference between whether only the module itself or the entire security system will be mounted. If in the first case it is possible to do independent work, then in the second it would be wiser to seek help from professional installers.

The basic algorithm for installing the GSM module is as follows:

1. Part of the instrument panel or instrument panel is dismantled to provide access to the alarm unit.
2. The removed signaling unit is disassembled and a board with a module is installed in the allotted place. On some models there is a special groove into which it is inserted. You must first install a SIM card on the module.
3. The main signaling unit is assembled, all wires and connectors are connected to it, and after that the entire unit returns to its place, all subsequent work is carried out in the reverse order.

The whole system is configured, the SIM card number is registered and then the system can be used.

Today, for the protection of vehicles are used various systems, ranging from conventional mechanical blockers to modern GPS alarms. The latter are becoming increasingly popular due not only to a reliable security system, but also to the convenience of managing the security system. In addition, thanks to the feedback function and the ability to remotely start the engine, you can control your favorite car without using a regular key at all.

GSM alarm (car) is a device that instantly notifies the car owner about an attempt to break into the car through the use of cellular channels. This option becomes possible thanks to a special module that monitors, that is, determines the location of the car by communicating with the base towers of cellular operators or GPS and GLONASS satellite systems. Outwardly, this module resembles a standard mobile device equipped with a screen, keyboard and connectors for connecting various sensors (opening / closing doors, windows, and much more). Sensors send information about everything that happens to the module, from which the alarm signal is redirected to the phone of the owner of the car. Thanks to this, you can prevent car theft by turning off the engine and quickly determine the location of the car.

Let us consider in more detail the advantages of such “smart” systems.

Benefits and basic commands of the GSM/GPS module

GSM alarm system for cars is developed taking into account the latest technologies that will not allow hijackers to use computer programs or the so-called grabbers to turn off the security complex. The effectiveness of alarms with GPS / GSM modules is due to the fact that the owner of the vehicle is always aware of the state of his car and where it is located. All information is displayed on a special keychain or on the phone. At the same time, you can control the car not only using a smartphone on which a special application will be installed, but also from a regular cell phone, by sending an SMS or a call. In addition, many alarms equipped with a module have a built-in microphone, thanks to which you can listen to what is happening in the car.

Another advantage is that the car owner can start the engine while at home. Moreover, you can program the motor to turn on at a certain frequency, for example, every hour for 10 minutes. Thanks to this, in winter time of the year, the “engine” of the car will not cool down and you can save a lot of time in the morning. You can also set the temperature threshold at which the systems will automatically work.

Healthy! It should be borne in mind that although the packaging with the alarm indicates a range of about 1,500 meters, in fact this distance will be much less. The fact is that such measurements are carried out in areas located far from cities, where the signal does not encounter any interference. In the city limits, such systems will catch at a distance of 300-500 meters. Therefore, if you live on the top floor, be sure to check the actual signal range.

Speaking about the advantages, it is worth mentioning the ease of installation of such a security system. To do this, you do not need to contact a specialized auto center. You only need to fix all the sensors, insert the SIM card into the appropriate slot and activate it from your mobile phone.

• monitor the status of the alarm and receive information about its operation;
• transmit the panic button signal directly to the security console;
• listen to the interior of the car;
• enable and disable the protection mode;
• disable preliminary or main shock sensors;
• auto start for cars without alarm;
• block the motor completely.

When choosing a system, pay attention to all these options, as well as to the manufacturer of the security complex. Today, the Ghost and Starline devices are the most popular.

Ghost systems

Depending on the modification of these devices, the availability of certain modules and additional accessories will depend. For example, an alarm in a Ghost car with an immobilizer will have a number from 510 to 540. The GSM alarms we are interested in can be identified by the first digit - 8 (for example, 810, 820, 830 and 840). All these modifications have the following characteristics:

• CAN controllers, thanks to which reliable integration with vehicle systems is carried out.
• The "PIN to drive" function, which acts as an additional protection, rjulf, in addition to using a special electronic key, the car owner must enter a special code.
• Sensors of external influences (tilt, shock, displacement and many others).

In addition, the alarm in the Ghost car is equipped with all the standard "chips", including remote control, microphones and the ability to auto-start the engine.

If we talk about the cost of these security systems with GPS modules, then:

• Prizrak 810 will cost you 15,000 rubles. It is only worth considering that this modification is not equipped with a special DDI 2.4 GHz radio tag, which allows not only to more reliably protect the car from theft, but also to exclude the possibility of a false engine stop. Also in this system there is no special relay that turns off the engine.
• Prizrak 820 costs a little more - 18,000 rubles. This system is also not equipped with a radio tag, but a mini-relay that turns off the engine is included.
• Prizrak 830 costs 17,500 rubles. The system is equipped with a radio tag, but there is no relay.
• Prizrak 840 for 21,800 rubles is equipped with all the necessary “gadgets” and will most reliably protect your car.

Starline systems

These systems appeared on the domestic market relatively recently (in 2013), but in a short time they won the hearts of motorists who distinguish Starline among the many security systems with GPS modules and the ability to autorun.

If we talk about the model range, then it is much wider than that of the previous manufacturer. In order to navigate in all products, you need to understand the simple labeling. For example, Starline A94 GSM has the following designation:

• A - device series;
• 9 - the presence of the autorun function (if it is 9, then it is there, if 6, then it is absent);
• 4 - generation of the system.

Today, Starline has several series. There is no GSM/GPS module in the “E” series, but you can install it yourself. "A" - has a control function from the phone and a more modern key fob. Series "B" is distinguished by increased noise immunity and the possibility of GPS monitoring. "D" - designed for SUVs, while the rest of the functionality is the same as for category "B" products.

At the same time, the security system is controlled through a special mobile application Telematika 2.0.

If we talk about the cost of such systems, then the most popular models will cost:

• E90 GSM about 16,000 rubles;
• A94 GSM can be bought for 18,000 rubles.

The latest model became the most purchased in 2013, when the company literally blew up the domestic car market with its powerful equipment. Today A94 GSM is also in great demand.

In custody

Of course, a car alarm with auto start and the ability to control via phone is the most reliable today. Such devices work quickly and allow you to prevent theft in a matter of minutes, and even if the car did leave the garage or the place where you left it, thanks to a special module your vehicle will be found long before the attackers have time to overtake it for disassembly. When buying such security systems, remember that it is better to purchase such products in specialized stores or dealerships. When buying on the market or "from the hands" you run the risk of getting the device program codes, which the attackers already have.

GSM/GPS modules for car alarms promptly inform the owner of the vehicle about its unauthorized use, start, stop or blocking of the power unit, as well as remote performance of service functions. The devices are universal, they can be installed on all brands of cars. Some systems are powered from the on-board network or others from the built-in power supply.

Informing the driver can be carried out by sending SMS or voice messages to pre-specified phone numbers of different mobile operators. Alarm control is performed remotely by means of telephones using a radio channel of a cellular network. Only when commands are given from specific phone numbers will they be accepted.

Status diagnostics can be carried out thanks to the signal of the LED lamp. Advanced car alarms are designed to work autonomously. To connect them, it is enough to connect the devices to the on-board electrical network.

Some Models GSM/GPS modules for car alarms have energy-saving modes to increase the lifespan. So, for example, in standby mode, the integrated battery will consume electricity only when a SIM card is present. And in the event of a power outage, the system will be able to function for several days.

Thanks to the use of GSM / GPS modules, it is possible to create effective security and telematic systems, which are usually connected via the CAN bus. Unlike conventional car alarms, devices of this type give a signal to the owner, regardless of the distance to him. The main thing is to have GSM coverage.

Main functions

Most GSM / GPS modules for car alarms perform the following functions:

• Connection via 2CAN bus

• Ability to operate in Slave mode

• Remote control of engine preheaters

• Controlling the standard car alarm with your phone

• Immobilizer bypass module control

• Possibility of automatic and remote start of the motor

• Obtaining data on the coordinates of the location of the car

Modern systems allow you to determine the location of the vehicle with an accuracy of several meters. This is the purpose of the GPS receiver. After sending the request, the phone device receives a text message with the coordinates of the location of the vehicle. Even in the event of theft, the owner of the car will be able to quickly find it or find out where a member of his family or another driver who is driving the car is now.

Modern modules can process over fifty commands, they can also be programmed. Several phone numbers can be stored in the SIM card memory, messages will be sent to them. Thanks to the module, you can find out why the alarm went off. Was it the reason for this opened door, starting the engine, triggering a shock sensor, disabling the parking brake, etc.

Branded GSM/GPS modules will greatly increase the protection of the car and the convenience of its operation. Thanks to them, the owners Vehicle they will always know where their four-wheeled friend is and what condition his main systems are in.
