Buying a vehicle is an important process.for many. And sooner or later we will think about ensuring the safety of operating your car. And this is assisted by a modern and reliable GPS / GSM car alarm, which will ensure constant control over the car at any time of the day or night.
What are the specifics?
Satellite alarm is moderndevice operating on the basis of two built-in modules: GPS and GSM. The first is needed to determine the location of the car relative to the world coordinate system, since it is a global network consisting of 24 satellites in orbit. The module is supplemented with special receivers through which communication with satellites is established. Good GPS / GSM car alarm detects a large number of satellites.
Main Components
Satellite signaling consists of main and additional equipment. From the basic components, each security system is equipped with:
- processor unit;
- interface software;
- antenna;
- sensors;
- GPS module.
Each alarm has its own designfeatures and programmed to a specific operation algorithm. As an additional component of the satellite line, a GSM module for car alarms, an immobilizer, a listening device and an alarm button are often used.
Why do I need GSM?
The GSM network is an important element of car alarms, soBy means of this module, an alarm text message is sent to the mobile phone of the car owner, which makes it possible to react in a timely manner, for example, to a hijack attempt. Signaling must necessarily be equipped with an antenna, the task of which is to establish communication with the satellite. It is installed in such a way that there are as few obstacles as possible in the transmission of a signal or data packet.
How does the security system work?
GPS / GSM car alarm consists of twoelectronic components that are mounted inside the car. The first block is needed to determine the geo-location of the car in relation to the satellites, the second - to ensure communication with the driver of the car. The advantage of using it is that satellite systems are connected to the control room, and therefore all important information will be sent directly to the security company. True, these services are paid.
No matter who the manufacturerequipment, each system has its own characteristics and functional differences. The effectiveness of its work is ensured by the quality of coverage of the zone by a specific mobile operator. The advantage of satellite security systems is that it will provide a multifunctional two-way communication between the car and the owner. All information is provided to him on a mobile phone.
Types and features
Modern GSM car alarms arepaging, duplicating or performing GPS monitoring. Paging is the cheapest and allows you to determine the location of the vehicle at a distance. The feature of GPS monitoring is the ability to determine the exact location of the car and remote control of the main systems of the car - ignition or engine. Elite class alarms include redundant, which not only carry out GPS monitoring, but also have a number of additional features. Modern GSM car alarms are characterized by a number of advantages:
- Large network coverage.
- Multifunctionality.
- The ability to track the movement of the car.
- Hidden installation.
But in the comments it is noted that satellite securityThe lines also have disadvantages, the most important of which is the ability to read the GPS code signal. In addition, if the car is underground, then it is impossible to catch the sensor signal.
Selection rules
Modern manufacturers offer a huge selection of car alarms. But experts and owners of equipment of different brands are advised to turn to a number of parts when choosing:
- if there is an immobilizer, then if necessary, you can block the engine;
- built-in motion blocking systems provide blocking of the fuel supply to the motor in the event that immobilizers broke off during the operation of the power supply circuit;
- remote start is an important advantage of modern security lines;
- The GPS module is a guarantee that the driver’s key fob will receive information about where the stolen car is located.
How to do it yourself?
Of course, modern models of car alarmsthere is a huge amount. But not everyone has the opportunity to purchase products of one brand or another. Note that the simplest GSM car alarm can be made with your own hands from the phone.
Those who have already done this kind of equipment with their own hands say that this process is simple, the main thing is to choose diagrams and descriptions. As components you need to prepare:
- old mobile phone with buttons;
- magnet;
- reed switch;
- wires;
- switch.
The assembly process is quite simple.First, the subscriber’s call is configured, that is, the current owner number for one button. Then the front panel of the phone is removed, since you need access to the board where the contacts are connected. At this stage it is important to properly solder the wires. So, if the functions of turning off the phone and hanging up fall on one button, then one wire is soldered to the button itself, and the second to the key that will be responsible for the call. If the end and stop buttons of a mobile device are different, then the wires are soldered to each of them.
After the chain is made, the door is puta magnet, and then the reed switch is tuned. Such a GSM car alarm with their own hands, as you can see, is created simply. But the essence of its work is different from the principle of operation of conventional signaling systems: when you try to open the door, the contacts of the reed switch are closed, and the phone will call the number that is programmed. With the help of an additional switch, the alarm system is armed and disarmed. Such a system will promptly warn the owner of the car about unauthorized access. In addition, the systems are notable for cheap creation, almost complete autonomy, and the phone will be charged periodically.
