Comparative analysis of GSM security alarms. Review of the best new home security alarms Review of home alarms

It’s probably no secret to anyone that those who like to profit from other people’s goods have met (and still meet) always and everywhere in huge numbers. But modern technologies have stepped so far forward that an attacker, even if he knew at least a thousand ways to penetrate private property, would find it quite difficult to carry out his plan. This is due to the fact that complex security solutions have recently appeared that combine quite a lot of capabilities. That's what it is security system for a private home, office, bank, enterprise, etc. Let's consider the most basic aspects regarding the functioning of such devices.

Security systems for a private home: types and general concepts

So, what is such a system? Here it is worth clearly distinguishing the complexity of combining the total management components, monitoring capabilities uninvited guests, types of notification, as well as options for connecting equipment.

Today, there are three main types of such systems:

• autonomous systems " Smart House»;
• wired systems;
• wireless (GSM security systems for a private home or office).

Let's briefly look at each type. But first, a few words about the equipment used.

Equipment used

If you look at it, any security system for a private home, office or enterprise, depending on the degree of complexity and the functions assigned to it, must include several mandatory components: a visual surveillance system or the use of motion sensors, a warning system for an attempted illegal intrusion (sound or light alarm, instant SMS sending to the owner of the house or office), the ability to block an intruder if he has already entered the premises, central control panel and unit uninterruptible power supply in case of a power outage.

It goes without saying that in the simplest case, most only motion sensors are installed. Among their types are the following:

• passive infrared sensors that respond to thermal radiation;
• beam infrared sensors with a reaction to the presence of a moving object in the area where the beams intersect;
• sensors that operate on the basis of the reflection of radio waves sent to a moving object (similar to the reaction of bats);
• contact magnetic sensors that are triggered when doors are opened;
• vibration sensors that detect the slightest vibration of the surface on which it is installed (floor, walls, etc.);
• sensors that detect damage to glass in windows or double-glazed windows;
• capacitive sensors for metal, triggered when the parameters of the magnetic field around them change;
• combined systems that include, in addition to the above, functions for detecting gas or water leaks.

Smart Home Systems

Perhaps today, Smart Home systems are the best. With their integrated installation, this includes not only a primitive alarm system for a private home. IN in this case several systems are combined into one. That is, the security function is combined with autonomous control of all devices in the house or cottage.

Again, depending on the complexity, such systems may have video cameras, motion sensors, and controls for gas or water appliances, and are used different ways notifications when any unpleasant situation occurs. As expected, such systems are completely autonomous, but if desired, their owners can connect them to specialized security services. After receiving an alarm signal, a special team goes to the scene to understand the situation and, if necessary, take appropriate measures.

The only drawback is the very high cost of both the system itself and the costs of paying for the services of a security company.

Wired security systems

A wired security system for a private home is the simplest and cheapest. Among the advantages of such systems, judging by numerous reviews from their owners, is that the sensors used do not need to constantly change batteries or charge battery packs.

Naturally, in case of emergency, provision should be made for installing a special uninterruptible power supply unit (similar to how this is done for computers). And it goes without saying that any sensors and cameras can be combined into one system. But it all depends on the needs of the home owner.

Wireless GSM alarm

Using wires for connections often causes legitimate difficulties. What if the house is renovated? After all, to lay cables, for example, in the walls, you will have to redo everything all over again, and this is a cost, and a considerable one at that. That is why many actively use wireless security systems for a private home or office.

There are two worth noting here important features. Firstly, all sensors or IP cameras are connected to the control unit either via Wi-Fi or a specific radio frequency. Secondly, (why they are called GSM systems) an SMS message is sent to a pre-registered number or several mobile phone numbers in case of an emergency or even a video image is broadcast. But such systems are an order of magnitude higher than wired ones.

Brief overview of the best manufacturers

As for everything that is now offered to the market, we can highlight several of the most popular manufacturers, both foreign and domestic:

• Visonic;
• Optex;
• Texecom;
• LifeSOS;
• Jablotron;
• Netatmo;
• Nest;
• Canary;
• Honeywell;
• Piper;
• Samsung;
• Kodak;
• Ademco;
• "Guardian";
• "Avalanche";
• "Granite", etc.

As many have probably already noticed, the list includes Samsung and Kodak. Their systems are mostly focused exclusively on video surveillance using a high-resolution camera with a rotation angle of almost 360 degrees.

It is worth mentioning separately about Honeywell products. In fact, this is not a whole system, but only the main unit (Honeywell Tuxedo Touch), with the help of which monitoring, alarms, and the functioning of heating, gas and water supply systems are carried out.

The products of other manufacturers are aimed at both private consumers and entire enterprises. Among the presented products you can find quite a lot of solutions by type of system.

Security systems for a private home: reviews

But here's what's interesting. Despite high quality products, Western manufacturers, for example, are not particularly popular in Russia. Feedback from owners shows that domestic systems look much more preferable in terms of operation. First and most importantly, they are designed to operate in post-Soviet power grids with a voltage of 220 V (and not 230 or 210 as in Europe or America). In addition, such systems do not turn off during significant voltage surges (in our country +/- 10-15%, in the West - +/- 5% of the nominal value).

On the other hand, systems from Russian developers feel great in conditions of low temperatures or high humidity, although in most cases they are somewhat inferior to their foreign counterparts in terms of functionality, as users note.

It is believed that one of the most interesting is an imported security system for a private home model range Vista from Ademco. In part, it duplicates the products of the Canadian company DSC, but its main feature is the possibility of almost unlimited addition of new equipment and integration, say, even with lawn watering systems or fire alarms.

Among foreign systems, users also note the products of the Israeli company Visonic, which has proven itself to be excellent when installed in cottage villages.

Professional security systems for businesses

The system, when compared with the private sector, is quite complex both in terms of the equipment used and in terms of management.

Based on the fact that production areas can be quite large, hybrid systems from such giants as AXIS COMMUNICATIONS, ASSA ABLOY, BOSCH SECURITY SYSTEMS, etc. are most in demand.

Their solutions in some cases involve the installation of additional repeaters to amplify the signal of the sensors, which makes it possible to increase the distance between them up to 500 m. In addition, it is possible to use not one, but several control panels (units) or special key fobs that allow you to give an alarm signal manually from any place if the main system does not work for any reason.

How to make a security system yourself and is it worth it?

In general, making security systems for a private home with your own hands is not so difficult. But the essence of the issue comes down to choosing the necessary basic and related equipment and connecting it correctly.

Of course, you can order services from a specialized company, but it’s easier to buy everything yourself. It will cost much less. As for the connection, anyone who knows the plus from the minus can connect the devices and the control unit.

Some craftsmen, however, try to solder circuits on their own, but they still can’t do it without professional equipment and fine tuning. So it’s better to buy all the devices separately. For example, the cost the simplest system of two sensors will cost an average of 100-120 dollars, systems a little more complex for a private home - already 300-700 dollars, but conversion into a Smart Home complex can amount to tens and hundreds of thousands of dollars, so think about whether everything is needed this is if such a system is not fully involved.

Telemetrics. 2015

The Russian, CIS and European markets offer a significant number of GSM alarm systems of various brands. Often the cost and characteristics of products are quite similar, and it can be difficult for the consumer to navigate this diversity and identify the characteristics of the device that are important to them.

Company In order to improve the quality of its own products and increase competitiveness, it continuously studies the features of wireless sets presented on the Russian market, including products of its direct competitors - Sapsan-GSM (Sapsan), MEGA-SX, Sentinel, Xital and others.

As part of this, our specialists conducted a small comparative study of the characteristics of some products on the market.

It is no secret to many that the vast majority of consumer electronics are made in Southeast Asia. At the same time, the quality of this electronics is different and ranges from Hi-End class systems to outright consumer goods. Therefore, you should pay attention to enough important point— some importing companies not only purchase their products in China, but also control the quality of production locally, and also bear warranty obligations in Russia to their customers. In addition, control programs and functionality of devices are adapted to the consumer, a range of additional sensors for devices (gas, smoke, vibration, etc.) is supplied, instructions are translated into Russian. Some companies use their engineering capabilities and develop devices themselves, using production sites in China only for serial production. Today we will talk about such companies.

By functional characteristics All alarms can be divided into three obvious classes.

1. Autonomous GSM alarms- sensor and device in one housing - you can control only one zone, one room. The quality and reliability of such devices often leaves much to be desired. There is no way to install the device in a room where access to an attacker will be difficult, as a result of which it can be easily disabled.
2. GSM alarms universal— allow you to connect a large number of different wireless and wired sensors in different rooms object. In addition, you can configure a large number of logical events, as well as control the temperature in the house, various appliances, etc. Such devices can be perfectly used as GSM security alarms for cottages and garages, while at the same time representing a system “ smart home» entry level.
3. MMS signaling(GSM MMS alarm) - allow you to transmit image or video from an object. The disadvantage of such alarms is the need to constantly connect the device to the Internet via a GPRS/3G/LTE channel or use MMS messages, which in turn leads to unstable operation in areas of poor network reception or at times of network overload, which often happens in dacha areas.

Let's try to understand the offers of the main suppliers of GSM alarms of the most popular, second class.

The table below presents the main, in our opinion, criteria that can help you decide on the choice of GSM alarms for your dacha or apartment.

Some aspects of choice

The consumer, as a rule, chooses a brand that has an adequate price, has been on the market for a long time, and provides warranty service. In addition, today with the development of the Internet and social networks many potential clients They are trying to form their opinion and make a choice, paying attention to reviews of GSM security systems, as well as using word of mouth.

We conducted a study of the offers of the main players in the security alarm market of one, but the most popular class of devices.

All devices have a fairly complete set of characteristics that allow complete control of surveillance objects.

Below are the characteristics that you should first pay attention to when choosing security GSM alarms.

Any driver is concerned about the safety of his car. Moreover, this concerns not only the prevention of possible breakdowns, but also the protection of the vehicle from thefts. This can be ensured with the help of security systems. But what should you pay attention to when choosing a car alarm? Which brands deserve customer trust? Is it possible to secure your car without extra costs? The answers to all these questions will be given by our rating of the best car alarms, which for the convenience of readers is divided into four most popular categories: budget, with auto start, with feedback and devices equipped with a GSM module.

Which alarm company is better to choose?

Before considering specific devices, we decided to talk about five well-known manufacturers of car alarms and the reason for their inclusion in our review:

1. StarLine. One of oldest manufacturers car alarms. The StarLine brand first announced itself back in 1988, and its debut remote security system went on sale just three years later.
2. Pandora. This year Pandora celebrates its 15th anniversary. And, it is worth recognizing, during this period the manufacturer managed to take a leading position not only in Russia, but also in the world, which is an important reason to trust this company.
3. SCHER-KHAN. Since 1998, the domestic brand Scher-Knan has been offering convenient and reliable, inexpensive and high-quality alarm systems for vehicles. Its advantages include the ability to operate at any temperature, which is very important for the varied climatic conditions of Russia.
4. ALLIGATOR. A well-known American manufacturer, which, despite the abundance of competitors, is constantly increasing in popularity. Thus, at the end of 2018, the brand entered the top three in terms of sales in the Russian Federation and the CIS countries.
5. Pantera. The last, but very honorable place is occupied by Pantera. This brand appeared on the Russian market in the 2000s, immediately displacing more famous manufacturers.

Which alarm system is better to choose?

Of course, every car enthusiast wants to choose the best device. And it doesn’t matter at all whether you select it yourself or rely on the rating of the best alarm systems for a car, the difficulties when purchasing, without setting clear requirements, will not become less. So, for an inexpensive vehicle that is not often left unattended, you can choose one-way budget security systems from the first category. For more serious requirements, look at the second and third groups. They are quite similar, but if you need remote engine starting functions, then solutions from StarLine, Pantera and Pandora are best suited. Do you want to keep your car under control, regardless of the distance from it? In this case, you need an alarm system with a built-in GSM module.

The main task of any security system is to notify of intrusion into a protected area. The security alarm should go off instantly as soon as an intruder opens the window/door.

There are two types of security systems. The first type works as a repeller: it makes loud sounds to scare the thief and attract the attention of others. The second type of security system transmits an alarm signal to the owner or to the private security console.

Principle of operation

Security alarms with video surveillance are quite complex. IN this system must include sensors, a signal receiving and monitoring device, actuators and cameras. As soon as an intruder makes his way into the protected area, the motion sensor is triggered and transmits information to the control device. This happens within 10 seconds; the normal time interval is 7-15 seconds.

Further, having processed this information, the control device transmits a signal to actuator about the activation of the security system, most often such a device is a siren. Also, at this time, the control and receiving device transmits a signal to a previously installed device, this can be an SMS to your phone about the system being triggered or an alarm signal to the security alarm panel.

Such security systems can operate through several communication channels:

• Ethernet – transfer of all information between sensors, control device and the owner via the Internet.
• Radio channel – operation of the entire system and transmission of alerts to security organizations via a dedicated radio channel.
• GSM – communication is carried out via mobile cellular communications.
• GTS – telephone communication (more often in older models of security systems).
