Options and rules for choosing an alarm for a garage

Security systems have been in demand for a long time, and there are a lot of offers on the market from various manufacturers. Today it is very important to be able to protect any property, and for this you need to choose a high-quality alarm system, not only for a house or apartment, but also for a garage or other premises on private territory. GSM alarm system for a garage is a system that transmits an alarm signal via mobile communications, that is, the owner receives an SMS notification on the phone. It is worth saying that this system is not much different from the system for an office building or apartment, there are only fewer auxiliary functions, but this does not make the alarm worse. That is, a garage alarm with feedback has only the necessary set of functions for a particular building.

System components

The security system kit includes:

1. GSM module. It is a small board that has a SIM card slot, a special antenna and feedback control, which is responsible for signal processing. An additional feature is that the mobile operator can be absolutely anything. Often the module is mounted in a metal panel and looks like a small box with a door; in addition, the design is equipped with a signal LED.
2. IR motion sensor. Often, for a garage, the manufacturer uses a passive infrared detector, which consists of just one device. The detector is mounted in the corner of the room at a height of up to 2 meters, this is necessary for the system to cover the entire area of ​​the room. You can also use an active IR sensor, which includes 2 elements: receiving and transmitting; this option can be successfully used to secure the entire perimeter. High-quality models are limited in the mass of the object.
3. Smoke detector. This element is optional, but still considered important. On average, it takes 5 to 10 minutes for a car to burn out, but if you have a smoke detector system in your garage, you can prevent a fire and serious damage. The device is mounted on the ceiling in the room, approximately in the center.
4. Magnetic contact sensor or SMC. This element includes a reed switch, which is also a sealed magnetic contact, which is mounted on the tray. The magnet is mounted directly on the gate. The mechanism is triggered if the sash opens and the contacts open.
5. Siren. Often this is a simple sound signal, but there can also be a light and sound signal that serves to scare away unwanted guests. The signal volume varies from 100 to 130 dB, and this can be compared to the sound of an airplane taking off.

Comparative characteristics of wired and wireless GSM systems

It is recommended to compare these two types of GSM alarms based on 6 main operational parameters.

• Energy dependence

When talking about wireless alarm systems, we mean autonomous devices that have their own power supplies, both for the central controller and for each external detector. Wired systems can also be autonomous, subject to the purchase of a powerful, expensive UPS (uninterruptible power supply unit), which is usually not included in the standard kit.

• Requirements for operating conditions

A wired alarm system is technically simpler; its components are less sensitive to external influences, both weather and man-made. Considering that wireless systems operate in the household radio frequency range, cases of false alarms are not uncommon. However, in more advanced models, the modulated signal is pre-encrypted. This not only eliminates false alarms, but also makes it difficult for an attacker to deliberately jam the detectors.

• Maintainability

Like any complex engineering system, GSM alarm systems can fail. In this case, it is easier to repair wired models. But the nature of failures in such systems is usually associated with the loss of contacts in the cable network. If the breakdown concerns the sensitive sensor of the alarm detector, then the difficulty of fixing it will be similar for both systems.

• Difficulty of installation

The undoubted advantage of wireless systems is that there is no need to lay and secure cables.

• Settings

Setting the sensitivity of the detection detectors and the operation of the central controller is the same for both types of systems with a comparable level of functionality.

• Price

The cost of wireless systems is significantly higher, however, when choosing them, you should also take into account the price of the cables used during installation and the uninterruptible power supply. The cost of operating both systems is virtually negligible given their energy consumption. Wireless systems will require battery replacement approximately every six months. Electricity costs for operating a wired model over the same period of time are much less.

Types of GSM systems

A self-contained garage alarm is the best option, but a mains-powered alarm also deserves consideration. But you should understand that it is quite rare that a garage is connected to the electrical network, and that is why an autonomous system is more common on the market. But in any case, the kit must have backup power, and for this a battery is used, since it is possible to cut off the garage from the electrical network and thereby disable the alarm system.

It is also worth saying that the GSM system is divided according to the assembly method:

1. Wired device. In this case, the working elements are connected to the central unit using a cable. The installation process is complex, but such an alarm is very difficult to silence.
2. Wireless. The sensor is connected to the central panel via radio communication and is powered by built-in batteries. Exceptionally high-quality models have an additional function that prevents the possibility of jamming the system.

Model selection criteria

The specifics of using GSM alarms to provide garage security dictate its own operational features, which not every model meets. First of all, this is the widest possible range of operating temperatures, especially if the garage is an unheated box. For metal garages, it is necessary to take into account the positive temperature limit, since in the summer such structures become quite hot.

The next most important thing is the duration of operation of the alarm system without an external power source. Considering that some garages may not be connected to a centralized power supply, preference should be given to models that were initially designed as autonomous, so as not to spend additional funds on the purchase of a backup power supply.

ADVICE! If you enter into an agreement with a private security service and enter their number into the device’s memory, the response time to unauthorized entry will be much shorter. In most cases, the speed of arrival of the arrest team is decisive in preventing an unlawful act.

How to make the right choice? Basic moments

A high-quality model allows you to simultaneously connect to several mobile numbers to which notifications will be sent. It is possible to configure such a system so that the alarm signal is sent not only to the owner, but to other people. An additional feature is remote monitoring and the ability to customize the system. Commands are issued using both a standard key fob and via SMS. For example, the owner has the opportunity to turn off the security system during the day, or set automatic start and shutdown times, and control sensors in real time. If the owner chose to additionally install a video surveillance camera, then the signal can be transmitted directly to the phone, but in this case a 3G network is required, and you can also receive MMS messages with photos.

Additional functionality of modern security systems:

1. Possibility of connecting an external microphone.
2. Security of individual zones.
3. Low signal quality alert.
4. Silencer protection.
5. Notification that the electrical power has been turned off.
6. Incorrect password selection.

Composition of wireless alarm

Let's look at the main components included in the GSM alarm set. A garage security system should include:

• main control unit with GSM module;
• at least one contact sensor;
• mobile phone or remote control.
• main control unit with GSM module.

The GSM module can be constructed separately from the control panel and connected to it via radio waves. In some cases, this can be very convenient, since the quality of communication is not the same everywhere, and for work you will need the best option possible.

A modern security system with a GSM module has the ability to communicate simultaneously with several mobile phone numbers. This allows you to call both the owner of the garage and backup numbers if the sensors are triggered. This means it increases the reliability and efficiency of the system as a whole.

The control unit may include an audible siren that is activated in the event of intrusion or burglary. Additionally, the kit may include a miniature camera, also controlled remotely using a mobile phone or remote control.

Security system based on a cell phone: installation instructions

It is necessary to prepare the following installation equipment:

1. Push-button cell phone with SIM card.
2. Magnet.
3. Hermekon is of a standard type or with three contacts, this will depend on the connection diagram.
4. Wired base.
5. Switch with one key.
6. Soldering iron.

The sequence of work is as follows:

1. A short call to the garage owner's phone is configured on the phone.
2. The phone must be carefully disassembled.
3. You will need a board under the keyboard.
4. You need to select a connection scheme. It can be different for each phone, for example, on one or two buttons.
5. Wires are taken, one of them is soldered to the call button, the other to the button for the command to turn on the keyboard.
6. A magnet is installed on garage doors.
7. The reed switch is adjusted so that when connected to a magnet, the circuit opens.

Thus, the principle of operation of the GSM alarm will be as follows:

1. When the garage doors are opened, the reed contacts close.
2. A call is made from the phone to the garage owner.
3. The location of the telephone will depend on the design of the garage space.

It is absolutely not necessary to try to install the alarm yourself; you can use the services of professionals, but in this case you will have to pay a certain amount for it.

Kinds

There are many types of automatic alarms depending on the required functionality - to protect a room or car from intrusion. Pricing policies are also different.

For home or cottage

Autonomous security alarm systems used to protect a house, cottage or apartment can be equipped with the following sensors:

• movements;
• opening/closing windows and doors;
• temperature;
• humidity;
• smoke and others.

It is important to choose a security system with a video recording service. In this case, when any sensor is triggered, information is sent to the mobile phone, after which video recording in the room is started. The shooting function can be activated to monitor online what is happening in the office or home in the absence of the owner.

In some trim levels there is a function such as “Smart Home”, when the owner configures the automatic switching on of household electrical appliances.

An autonomous security alarm system for a summer residence must operate without electricity for a long time. Therefore, it is important to select those models where the battery life is suitable in each specific case. There are quite a lot of options on the market that can operate in sleep mode and activate the protective function directly when one of the sensors is triggered.

Scheme of autonomous security alarm for residential premises

For garage

For garages, it is customary to use inexpensive systems equipped with a minimum set of sensors. In this case, you need to pay attention to the temperature regime. It is advisable to connect the service of a security company or police. In this case, the signal is received simultaneously by the dispatcher and the owner. It is possible to connect an autonomous GSM alarm not only for one box, but also for the entire garage cooperative.

For auto

Car alarms for cars without a GSM modem are installed less and less often. The security of autonomous anti-theft devices is worth the investment.

The models have many interesting features, for example:

• remote control;
• driver protection function;
• possibility of video and audio wiretapping in the cabin;
• tilt sensor (triggered when the car is towed);
• connection of additional functions (road assistance);
• range of action – up to 5 meters.

What is needed to organize GSM security

To organize GSM security, you need to purchase a set of autonomous alarms taking into account the maximum room temperatures. You can install the security system yourself or with the help of an alarm installation specialist. This is done simply, according to the instructions. The main thing is to position the sensors and synchronize them with the electronic configuration and control module. Mobile operator cards and batteries (if necessary) are purchased separately.

The ideal solution for protecting property would be to connect the system to the security console.

Description of autonomous GSM alarm system

Autonomous wireless alarms work thanks to a unit enclosed in a sealed container, a GSM module and special sensors. The system is activated and controlled using the key fob. Autonomous and uninterrupted operation of the device is ensured by a built-in battery. The average duration of operation is 12-35 hours. An alarm system has been developed in Russia that can operate autonomously for up to 12 months.

Functions

In addition to uninterrupted security, autonomous GSM alarm system has a number of additional functions:

• light and sound effects;
• photo and video recording of what is happening;
• signaling to the police or security service;
• the presence of a system that prevents movement or a locking system.

Principle of operation

Sensors are installed in hazardous areas (door, window) or along the perimeter of the building/territory. They detect changes in the installed object and transmit a signal to the electronic unit. Here this information is processed and sent to a mobile device or landline phone number via SMS or MMS. The algorithm of actions is set by the owner of the security complex. Simultaneously with the transmission of the alarm signal, the autonomous alarm system activates additional external devices depending on the model and configuration.

Differences

Security systems differ in their ability to work in different conditions and functional features. Built-in sensors use different frequencies, which is important to consider before purchasing the selected model.

Advantages

The advantages of stand-alone GSM alarms are as follows:

• the presence of additional sensors that are able to detect gas, water or fire leaks in time;
• the ability to receive photos, video and sound from a protected object;
• 2 slots for different SIM cards to ensure better coverage when one network fails;
• no monthly subscription fee;
• you can connect to paid services of security companies;
• minimum equipment compared to wired alarm systems;
• ease of installation;
• the ability to use one GSM alarm system to protect 2 buildings (range 100 meters).

Flaws

The disadvantages include the following:

1. The frequency 433.92 MHg, popular among Chinese developers, is quite easily jammed by the LPD radio station. Severe interference is generated and the alarm signal is not sent.
2. The need to periodically change batteries and charge the battery.
3. Dependence on the network coverage of the mobile operator.
4. Difficulty of repair.
