Owners of personal vehicles tend to worry about its serviceability and integrity. For these purposes, a garage is used, since it is able to reliably protect the car. However, modern attackers have learned to easily get inside and steal a four-wheeled friend. But car enthusiasts have found a way to counter them with a GSM alarm for the garage. Next, let's figure out which of its many versions to choose.
Functions
They consist in creating reliable protection for a garage located far from residential areas. If there is no video surveillance and security guards, these are excellent conditions for intruders to penetrate. Even improved locks cannot become a barrier to entry if there is no additional protection. But the GSM system is another matter, of course, by itself it will not stop thieves, but will transmit information about unauthorized entry by alerting the owner to a smartphone or phone.
After receiving the message, the car owner will be able to notify the law enforcement agencies or go to the garage on his own.
Technical features
The usual set of security systems based on this version of the alarm consists of electronics for processing and transmitting information, motion sensors and unauthorized door opening, and a remote control. Advanced versions are equipped with surveillance cameras, microphones and sirens in various variations. Additional functions can scare intruders, because they will know that their appearance has been noticed and they are being monitored. In most cases, this is enough to get thieves out of the garage.
But that's not all, as the extended list of optional equipment offers other useful features. You can install various sensors that detect temperature changes, the appearance of smoke, deliberate disconnection of electrical voltage, unnatural vibrations. Due to this, the capabilities of various security systems are noticeably increased, and the car is protected more reliably.
This type of security system works on the basis of continuous reading of information from various sensors. If one of them detects unnatural activity, a signal is sent to the central unit, for which a high-frequency radio signal or a separate trunk wire is used.
The electronic module starts working - a sequential list of actions is performed in case of a break-in:
- activates the alarm and other provided protection methods;
- sends an alert to all numbers entered in the base;
- if one or more cameras are connected, a photo or video is sent with information about the situation in the garage;
- if the setting is done, the security system dials a landline or mobile number.
But protection against burglars is not the only area of application for GSM signaling. It is able to warn of the occurrence of other hazards to transport or the integrity of the garage. We are talking about a possible gas leak, since many cars operate on its basis, a significant increase in temperature (fire or minor fire), the appearance of smoke, an unknown reason for a power outage. To do this, you need to connect additional capabilities of the security system - we have already talked about them.
Among the many additional features, it is worth highlighting the "Mayak", as it will provide information about the location of the car. This will help keep your vehicle safe even outside the garage.
Usually, notifications from GSM-signaling are transmitted using cellular operators. But it is possible to send a signal about various problems with the car using a special key fob.
Diversity
They are offered on the basis of two types, by analogy with GSM-signaling for the protection of the inviolability of a summer residence. Let's consider them in more detail.
Wired version Allows the use of a variety of sensors using a trunk cable connection. This will require many wires to be carefully laid, which can be time-consuming and demanding. But their advantage lies in the fact that the signal transmission cannot be jammed with the help of various equipment from the arsenal of advanced robbers. Even in the case of using special means, the signal will still go to the central unit, and the stages of protecting the garage and its contents will be sequentially carried out
Wireless version much easier at the stage of installation and operation. The sensors send a signal to the electronic module using a secure radio signal. A commonly used channel is very difficult to muffle. But especially experienced attackers are sometimes able to deal with this obstacle. Because of this, it is recommended to use a combined version of this type of security system. Due to this, the vehicle will gain truly reliable protection, and the owner will be confident that it will not be easy for thieves to go unnoticed, since sometimes they are able to even get to the wire signal transmission line and block it using a technical method, or simply cut it off
It is best to choose options with a video camera and GPS for home and summer cottages that have received positive reviews. The most famous manufacturer of such protective systems is the Arduino brand. Also, Russian models have proven themselves well, which can work even at temperatures of - 30 C.
Power supply methods for protective systems
They are divided into autonomous ones and those operating from a network with a standard voltage at the level of 220 V. An independent power system is necessary in cases of disconnection of the main one, since some attackers have learned to disable it. In addition, sometimes an emergency occurs and power from the network becomes impossible due to various reasons. Don't assume that autonomous systems will work for a short time. It all depends on the type of batteries used - some versions can be continuously operated throughout the year.
The functionality based on the operation of the autonomous power system will noticeably decrease. We recommend using an integrated approach - use the usual version of the power supply as the main one, and if it is unavailable, switch to the stand-alone version.
Choose the GSM signaling correctly
A large number of devices are now being sold for high-quality protection of the garage and its contents from various criminals. For many, the question of cost comes first, since the growth of the functions of the security system involves an increase in its price. Before making a choice, you need to assess financial capabilities and build on them.
We recommend paying attention to specialized GSM systems created exclusively for the garage:
- the garage version called smart watch 4 has a reasonable price and sufficient functionality;
- the guard-garage system has similar properties.
But it is necessary to realize that the listed systems will not provide full protection. Usually they are not even included in the ratings of the best GSM systems, since their functionality is very limited. To ensure the safety of the car, we recommend that you do not skimp and forget about budget systems. If cost is very important, you should pay attention to the middle price category:
- the stand-alone version of the SafeHouse alarm is not too expensive, but sufficiently reliable;
- an advanced modification of the watch 1M has no less interesting characteristics and an acceptable price.
DIY garage protection system
This option is possible if the car owner has some skills in the field of various electronics. It can be considered an alternative to too expensive security systems or very cheap, in fact, offering almost nothing. The fact is that thieves can easily neutralize too simple alarms, and sound effects are not able to lead to an attack of panic in experienced hijackers. In this case, you can provide the garage with its own protection using various purchased accessories. The finished version is usually of high quality and significantly reduced price.
You will have to rely on specific knowledge and various materials with tools. To create a security system on your own, you need to prepare:
- a phone for use as a GSM module - an inexpensive but workable model will do;
- a powerful enough magnet in conjunction with a reed switch;
- efficient and reliable switch;
- set of conductors;
- necessary mounting elements;
- various tools such as a soldering iron, pliers and various types of screwdrivers.
Almost all of the above is available to car owners with minimal electronics skills. If something is missing, you can buy it at a specialized point of sale, for example, it is in the city of Krivoy Rog.
Mounting method
The phone is improved to communicate with the required number by pressing one button. One of the keys is used to make an operational call, and the conductors are connected to the telephone board - they are connected to a remote switch designed to replace a standard button on the surface of a mobile device. Certain functions can be assigned to different buttons. For this, wires are connected to each of them, and a reed switch based on three contacts is used.
All the necessary connections are made using a soldering iron. Various elements are installed based on the garage area. A special magnet together with a reed switch is mounted on the door surface.
After that, the correctness of the connections is checked - it is necessary that a reliable connection of the contacts occurs in the event of unauthorized entry. This will activate the protection system and send a signal. The notification speed is about 2 seconds, so this version copes with its task very reliably.
To prevent the possibility of failure of such a protection system in the event of a quick closing of the door, a device is installed that allows keeping the closed state of the contacts even after the door has returned to its original position. This is one of the simplified self-defense options, but other versions can be provided for the garage.
In this video, you will find an overview of the GSM alarm system for the garage with its pros and cons.
