Security devices for the home. Security of private houses and cottages

The number of burglaries in our country has not decreased for a long time. Therefore, Russians have no choice but to take care of their own safety. In this regard, the demand for alarm systems of various types is constantly growing. At the moment, a rather promising direction in this area is the production of alarms operating in mobile networks. The characteristic features of GSM alarm systems for the home are reliability, versatility and low cost. There are quite a few varieties of such security systems on the market, which allows you to choose a set of equipment that will be ideal for a particular country house or apartment.

Operating principle of GSM alarm

This system consists of a communication module with a SIM card installed in it and several external devices. The base unit is pre-programmed with a phone number to which an SMS notification is sent if one of the sensors is triggered. The device allows you to record several numbers at once. Consequently, a signal about the start of a fire or unauthorized entry into the premises can be simultaneously sent not only to the home owner, but also to the relevant services.

The design of the GSM alarm can also provide for external warning devices, which include sirens, bells and spotlights. A number of devices have a feedback function. That is, they can be controlled remotely using a mobile device. In the case of a comprehensive security system, various sensors are connected to the communication module, which expand the functionality of the system.

Types of sensors connected to the base unit:

1. Glass break sensor.
2. Contact sensor (installed on windows and doors).
3. Motion sensor (radio wave or infrared).
4. Wall break sensor.
5. Sensor sensitive to increased air temperature.
6. Gas leak detector.
7. Smoke sensor (fire detector).

Absolutely all sensors are triggered when the electrical circuit opens or the resistance changes, caused by an event or external factor. For example, a vibration sensor is triggered in the presence of rhythmic impacts, which are typical when trying to break through a wall. If there is smoke in the air in the fire detector, the circuit opens. When choosing a base unit, you must take into account the size of the room, since a strictly limited number of sensors can be connected to it. Sensors for temperature increases, gas leaks and wall breaks are installed quite rarely. But all other types must be present in the GSM alarm system.

GSM alarm selection

This is a rather serious issue that needs to be approached with the utmost seriousness, since the safety of property and the level of safety of housing depend on it. Let us immediately note that GSM signaling is capable of performing its functions fully only if there is constant mobile coverage. Therefore, GSM security systems are useless in areas with poor communications.

The kit includes the following equipment:

1. The main programmable unit equipped with a GSM module.
2. Several sensors.
3. Power unit.
4. Connecting wires.

Installing a multifunctional alarm system involves the use of both fire and security sensors. To achieve the maximum level of safety, a number of requirements must be met. Contact sensors are mounted on all doors and windows. Glass break and motion sensors should be installed in every room. In addition, each room is equipped with at least one fire detector. A high-level security alarm system includes, in addition to GSM sensors, video cameras.

If it is necessary to install a simple alarm system, then the number of sensors and detectors is reduced to a minimum. However, it is imperative to lock the balcony and entrance doors. Volumetric sensors are installed in such places that doors and windows fall within their coverage area. GSM alarms are classified not only by functionality and the number of sensors used. These security systems can be wireless or wired.

Wireless alarm ideal for country houses, as they allow you to install sensors on objects remote from the premises, for example, gates and car entrance gates. When installing it, you don't need to fuss with cables. The signal to the base unit from the sensors is received via a radio channel. Elements of such a system can be located at a distance of up to 50 meters from each other.

Wired GSM alarms most often installed in apartments. Installing such systems is not always convenient. The cable carries electricity to power the sensors.

The most popular GSM alarm models

If we compare wired and wireless GSM alarms for the home, then wireless ones look preferable. They are more popular among consumers. Such systems can be installed without the involvement of specialists, since there is no need to perform complex installation work.

Sentinel is a wireless GSM alarm system designed to provide security for a country house or apartment.

IN The package includes the following equipment:

1. Control Panel.
2. Window and door opening sensors.
3. Motion sensors.
4. Remote control key fob (2 pcs).
5. Piezoelectric siren.

Up to 99 sensors can be connected to the base unit simultaneously and 2 sensors are connected via a two-wire line.

The operating mode can be changed in one of three ways:

1. Remotely (requires a mobile device).
2. Remote control-key fob.
3. Buttons located on the control panel.

KARKAM GUARD T200 is a GSM security system that can work simultaneously with wired and wireless sensors. The system unit can be programmed with up to 5 numbers for dialing and up to 4 numbers for sending SMS. Thus, when an incident occurs, not only the owner of the apartment or house is informed, but also the security services. The alarm design of this model provides 2 wired and 8 wireless zones. Various types of sensors can be connected to the device with the possibility of grouping them.

The delivery set includes the following devices:

1. The main unit equipped with a GSM module.
2. Siren.
3. Wireless sensors (2 pcs).
4. Remote control key fob (2 pcs).
5. Power unit.

The main unit is designed with an internal battery. With its help, the security system is maintained in operation during a power outage. The alarm can operate autonomously for at least 10 hours.

Advantages and disadvantages of GSM home alarms

These security systems stand out against the background of other similar devices. One of the main advantages of GSM alarms is the ability to notify people about the occurrence of a specific event. Also, such systems allow you to monitor the status of a protected object online. If sick or elderly people live in a house or apartment, then they only need to press the “Alarm” button on the remote control. As a result, the signal will be sent to several numbers at once.

It is possible to program a voice message that will be played when the sensor is triggered. Access to the system is limited by setting a password. You can connect as many sensors to the main unit as required to ensure the maximum level of room protection. Wireless security systems are installed by homeowners themselves. All sensors of such alarms operate autonomously, so you need to periodically check the charge level of their batteries.

However, there are also disadvantages. The most noticeable is the dependence of the system’s operation on the quality of mobile communications. With regular network outages, all the advantages of GSM alarms are reduced to nothing. In addition, the signal sent by the system can be easily suppressed. Special devices are used for this. It is also necessary to pay the operator’s services on time. Otherwise, the connection may break at the most inopportune moment.

GSM alarm installation

Any person with basic knowledge in the field of electricity and the necessary equipment can install a security system. The installation technology is described in detail in the accompanying documentation. However, there are several nuances that are worth considering.

Volumetric motion sensors should be mounted at an inaccessible height. When performing this work, you need to take into account the size of the gripping area. All necessary data is presented in the technical documentation. When choosing a GSM alarm system, you need to pay attention to the presence of an anti-sabotage zone at the motion sensors. Reed opening sensors are rarely installed on decorative and metal-plastic windows. To maintain the attractive appearance of window structures, it is better to give preference to “Storm” sensors, especially if there are several windows on the same wall.

An opening sensor is installed on the door. To increase the level of security, it is recommended to duplicate the door area with a motion sensor. The front door is the most vulnerable place in a house or apartment. You also need to lock the balcony door. The most accessible places for penetration must be duplicated. That is, the same zone must be monitored by different types of sensors connected to different lines of the main unit.

Home security

Every person wants to ensure the safety of their home, property and themselves personally. That is why the decision is so often made to buy a security alarm for a house or cottage.

There are many methods of protection: windows with higher burglary resistance, vandal-proof doors and blinds, private security services, technical means. The Gulfstream company offers a comprehensive approach to protecting cottages. Our specialists will assess the risks and identify vulnerabilities to create a unique country house security project.

Home alarm system: project development

A security alarm for a private home should be adjusted and selected taking into account potential threats. The company's engineers consider each case individually, taking into account certain aspects:

1. Architectural features - the shape and size of the house. The larger the area of ​​the building, the more vulnerable spots through which an attacker can enter the house. The number and type of sensors should be adjusted based on the number of entrances, which include doors to the terrace and balconies. They act as an “easy target” for a burglar compared to regular entrance doors.
2. Illumination and surroundings of the object. When developing the project, lighting will be taken into account and how well the building and the surrounding area are visible.
3. Infrastructure and location. Detached objects located in “out of the way” areas represent objects with a high risk of robbery. With this arrangement, the sound signal will not scare off intruders, and therefore connection to the security panel is a prerequisite for home alarm systems.

Based on these features, the company engineer will select the required set of sensors and create a diagram of their placement.

Home security cost

The price of a home security system kit depends on the number of sensors selected. The basic package includes:

• Control panel - 1 pc. Security system control element.
• Wireless keyboard - 1 pc. The device is necessary to activate/deactivate the security system using a contactless key or personal code.
• Contactless key - 3 pcs. Used to activate/deactivate the security alarm.
• Door opening sensor - 1 pc. The device reacts to an attempt of unauthorized entry into the facility.
• Motion sensor with photo confirmation option - 1 pc. The infrared sensor responds to human thermal radiation (the difference between the temperature of the room and objects).
• Motion sensor - 2 pcs. The security system element reacts to movements inside the object.
• Warning sign - 1 pc. Notifies others that the object is under protection.

Additional features of the system include:

• Portable panic button. The device can be carried with you and, if necessary, send an alarm signal to the Central Monitoring Station.
• Smoke detector. The element detects smoke in the room and, when alarming indicators are detected, activates an audio signal and sends data to the operator at the Central Monitoring Station.
• Wireless control panel with TC function.
• SMS notification option. The owner of the security system will receive alerts not only in the Gulfstream mobile application, but also via SMS. Maintenance (monthly).
• Water leakage sensor. The device allows you to avoid flooding of the house and take timely measures to eliminate emergencies. Monitoring is carried out over the entire pipeline system in the house, heating systems.
• Temperature sensor. The device is used to monitor room temperature and prevent fires in the house. In addition, when the air temperature in the room drops below the set value, the sensor is triggered and an alarm signal is sent to the operator at the Central Monitoring Station. In addition, a notification about a drop in temperature will be sent to the client’s mobile application.
• Gas leak sensor. A universal device that determines the level of concentration in the air of various types of gases, such as butane, propane and others.
• Smart plug. Allows you to control electrical appliances in the enterprise. From his mobile device, the alarm owner can turn on/off the sockets in the room.
• Safe box. An outdoor safe box is necessary for storing keys to the gates of a country house. When an alarm signal is received, the rapid response team (RRT) will be able to dial a special code, receive the keys and enter the yard to inspect the area around the house.

The cost of installing a security alarm in a private house

The cost of installing a security system is free of charge. A Gulfstream engineer will install the system in 2-3 hours, configure sensors and individual scenarios, and also show how to use the mobile application.

Sometimes there is a need to install a simple and inexpensive security alarm. Without unnecessary bells and whistles that manufacturers add to it in order to expand the functionality of their system and somehow distinguish it from other competitors. A cottage, a garage, a household outbuilding or even a greenhouse; in such places it is not always advisable or profitable to install a full-fledged security system.

In this article we will look at several devices that claim to be simple and accessible to anyone who wants to protect their property from intrusion by uninvited guests.

What should such an alarm be able to do?

• react to an intrusion (some external influence - movement, the door was opened, hit, etc.);
• sound a sound signal to scare off the intruder;
• have the ability to arm and disarm;
• It is advisable to consume little electricity.

The purpose of this device is not so much to block access to the house, but rather to scare away the thief. Having heard a loud signal, he will not want to take risks and will not climb into the room; in addition to the psychological impact, it may also attract the attention of neighbors.

Security alarm based on motion sensor

The simplest security alarm for a home can be made with your own hands based on a conventional household motion sensor for lighting, which is installed in entrances to save energy. But instead of a lighting lamp, you can install a siren.

What will you need for this?

• Motion Sensor– you can buy it at any hardware store, for example OBI or Leroy Merlin. It is necessary to pay attention to the operating voltage of the sensor - we need it to operate from a 220V network; the viewing angle depends on the external design of the sensor (wall-mounted or ceiling-mounted) and the lens used (can be wide 180 degrees or corridor type). Average cost from 400 to 800 rubles;
• Siren operating from a 220V network. For example, PKI-3 “Ivolga-220”, average price 250 rubles. Can be purchased at radio stores;
• Regular switch, to turn off the alarm. Any will do, from 100 rubles. and higher.

The connection diagram is shown below:

You need to choose a motion sensor that has at least two types of adjustments - time adjustment (TIME) and sensor sensitivity (SENS). Using the first one, it will be possible to set the activation time of our alarm, i.e. siren sounding time. This value is usually set for five minutes. The second adjustment changes the sensitivity of the sensor, for example, if it does not respond to you or to reduce so-called “false alarms”.

A switch will be needed to turn off the device when you are in its field of view and turn it on when you leave the room. It is advisable to install the switch covertly, so that after activating the security alarm you will not fall within its range of action. In addition to the siren, you can also connect a regular light bulb for double impact on the intruder.

The main disadvantages of this implementation will be that some models of motion sensors, after being turned on, require from 1 to 10 seconds to “stabilize” and switch to standby mode. If you come across such a sensor, you need to add a time relay to the overall circuit, which will keep the siren turned off while it is turned on.

There are also miniature motion sensors on sale that operate on 12V, for example, model DD-03. You can also create a simple alarm on them, but you need to connect it to a 12 volt power source or a battery. Thanks to this, the system will be non-volatile and work even if there are power outages.

Security alarm from a ready-made kit

The simplest security device based on an autonomous alarm system can operate wirelessly. In stores for radio amateurs you can find two options - based on an infrared sensor (aka motion) or a magnetic contact sensor that reacts to opening. True, the choice is not large enough and you will often have to go shopping to find the product “in stock”. Therefore, the easiest way to purchase this product is to order it in one of the large online stores.

Kit based on an infrared sensor.

An example is the Chinese alarm system under the loud name “Alarm mini”. Consists of the IR sensor itself, a mounting bracket and one or two key fobs. The kit includes clear instructions for installation and operation. 4 AA batteries are purchased separately, but can also be powered by a 6V power adapter (sold separately). Installing it yourself is not difficult.

After inserting the batteries into the device, you need to install the unit itself in such a place that its lens is directed towards the protected area. The front panel has an infrared receiver window for controlling the alarm from remote controls. A lens that “detects movement” in the controlled area, operation lights and a siren.

We press the button on the remote control - the green LED lights up, which means the exit report has started (15-20 seconds), so that we have time to leave the apartment. Then the green eye goes out - the device has started working. Now, as soon as there is any movement in the room, a person will pass, a dog or cat will run, the red LED will light up and after 15-20 seconds a very loud siren sound will be heard. The device works!

A set based on a magnetic contact sensor.

A security alarm based on an opening sensor is a main unit that contains a sensor with open contacts and a magnet for closing these contacts. You need to set them up against each other so that there is direct contact between them. If a thief breaks into the house, when a door or window is opened, these elements move away from each other and an alarm siren sounds.

Such an alarm can be used mainly to scare off intruders and its main advantage is its low price, about 100 rubles per sensor. And very simple installation, there is adhesive tape on each part, just remove the protective layer and stick the sensor on the front door or window.

Often such kits are used to protect the perimeter of the house while you are inside, for example, sleeping at night. The sound of the siren will wake you up and you can take any action to protect yourself.

Burglar alarm simulator

In urban multi-storey buildings, it is becoming popular to set the apartment on security; in this case, expensive equipment is purchased to protect against intrusion, and the signals are transmitted to the remote control of the security company. But not every owner can afford this, and it’s not always justified.

Remember on cars such a device, under the windshield, usually near the steering wheel, there is a red LED that flashes or is constantly lit? He warns that the car is under guard. Likewise, for an apartment or cottage, there are similar designs or, in other words, burglar alarm simulators. They are designed to scare away unprepared and unprofessional thieves or burglars.

To make such a simulator, you need to buy a red LED (for example, this AL307), a mounting box to house it, a 100 Ohm resistor, a switch and a compartment for two batteries. For the entire set you will need to pay approximately 100 - 200 rubles. Depending on the characteristics of the LED, a current-limiting resistor must be connected to it in series. A radio store will help you choose the right resistor (unless, of course, you have a Soviet AL307 LED, as in our example).

When leaving the house, we turn on the constantly glowing LED, and when we return, we turn it off. Strangers will think that the apartment is on an alarm system.
