Automatic security alarm. Modern burglar alarm The burglar alarm system is used as

The issue of protecting the home during the absence of the owners is completely solved by installing a security alarm. Before proceeding with the installation of this device, you should understand the varieties and diversity of the modern security alarm market. How to choose and install a burglar alarm in an apartment, we will learn further.

The device and design of the security alarm

The security alarm system is a combination of three components, which are expressed:

• reception and control equipment;
• fixing sensors;
• execution type devices.

Fixing sensors act as a catching device and react to changes in the state of the apartment.

In accordance with the principle of operation, sensors are divided into devices:

• infrared type,
• radio wave type
• vibration type,
• capacitive type,
• magnetic type,
• beam type,
• acoustic type.

Depending on the functional purpose, sensors are distinguished:

• changes in temperature, humidity,
• opening, closing doors,
• window sensors,
• motion sensors,
• water flood sensors, etc.

The main function of the sensors is to control a certain parameter and transmit a signal to the receiving equipment.

A receiving and control type device monitors and controls all sensors, and then transmits a signal to the executing devices.

Actuators notify the owner of the apartment or the security service about an offense or a change in a certain sensor parameter.

The principle of operation of the security alarm

The apartment security alarm scheme is based on the operation of sensors:

• magnetic-contact type, which are installed on windows or doors and signal the owner about the opening;
• volumetric type sensors - are responsible for changing the movement;
• window glass break sensors.

The principle of operation of the security alarm is to fix changes in the parameters of the sensors. For example, if the sensor detects extraneous movement in the apartment, the state of the loop changes and the signal is transmitted to the control and receiving device. Depending on the program, the KPU turns on the siren or notifies the owner of the violation using SMS or auto redial.

A special password is required to disable the system. It is possible to use additional functions, such as automatically switching on the light in the apartment, locking the door, turning off certain devices.

Benefits of Installing a Burglar Alarm

1. Installing a security alarm in the apartment will allow you not to worry about the safety of material assets during the absence of the owners.

2. A large number of security alarm systems allows you to choose devices in accordance with individual preferences and features of the apartment.

3. The self-contained security alarm system does not require additional investments to pay a monthly fee to security agencies.

Varieties of alarm systems for apartments

In relation to the installation method, burglar alarms are distinguished:

• wire type,
• wireless type.

A wired security alarm system consists of several sensors that are connected around the entire perimeter of the apartment using a cable. This system has a number of disadvantages:

• damage to one area leads to failure of the entire system,
• the installation of such an alarm requires repairs to install the cable.

The wireless system is more popular and consists of sensors that run on batteries. Battery life is 9 to 12 months. Fixing the sensor does not require additional repairs or special knowledge. Just follow the manufacturer's instructions.

In relation to the type of notification, there are:

• horn alarm,
• GSM alarm.

An alarm in the form of a sound siren can only scare off robbers and attract the attention of neighbors. The cost of such a security system is much lower than GSM.

A wireless or GSM alarm system is a collection of sensors that transmit an alarm signal to a control and receiving device. This device sends a signal about the failure of the sensor to the owner of the apartment.

Advantages of installing a GSM alarm system in an apartment:

• notification via SMS or auto-dial will allow you to quickly respond to the signal;
• a wide variety of sensors will allow you to choose devices that will suit the individual needs of any consumer;
• does not require repairs in the room;
• a high level of protection against hacking guarantees the safety and security of material property;
• the ability to transmit a signal not only to one subscriber, but also to several, including to a city number;
• some models are able to transmit a signal not only to the owner, but also to fire and security services.

In relation to the addressee, security systems are distinguished:

• autonomous,
• official.

In the first case, the violation signal is transmitted directly to the owner of the apartment. During the use of an autonomous security alarm system, the signal is transmitted to special security services, with which the customer concludes an agreement in advance. In this case, you need to pay monthly security services.

1. Before buying a security alarm for an apartment, you should decide on the type of security system.

2. The best option for security alarm is GSM system.

3. Pick up several sensors that respond not only to one parameter, but to various changes in the environment.

4. To ensure the independence of systems from electricity, it is better to use battery-powered sensors.

5. When protecting large material assets, it is recommended to install a video and audio surveillance system.

6. If the apartment is located far from the network tower or there are communication problems for GSM systems, additional amplifiers are required.

7. Some systems are able to instantly photograph the fact of the offense and send the photo to the owner of the apartment in the form of MMS.

8. To ensure reliable protection against hacking, it is recommended to contact special security organizations that are responsible for the safety of property.

9. If you want to install the alarm yourself, choose systems with detailed installation instructions.

10. It is better to buy a burglar alarm for an apartment from the manufacturer, thus ensuring the reliability and guarantee of long-term operation of the equipment.

11. Requirements for a quality security alarm system:

• availability of a certificate of compliance with all norms and acts of legislation,
• manufacturer's warranty,
• high service life,
• high-quality materials from which the system is made,
• it is not possible to turn off the alarm outside.

12. Burglar alarm for apartments price depends on such factors:

• number of sensors
• parameters of the receiving and control device,
• type of alarm
• installation method,
• company manufacturer,
• apartment area,
• individual preference,
• number of additional features.

Sensors of magnetic contact, wire and push-button type.

Installation of a security alarm in an apartment

Depending on the installation method of the alarm system, further actions are:

• with quick activation of the sound siren,
• with the transmission of a signal to the security service, when concluding a contract,
• transmission of an alarm signal to the owner of the apartment using GMS,
• inclusion of special protective devices: gas aerosols, switches, automatic door locking, smoke generators,
• signal transmission along with the public service: the police or the fire department.

Mandatory components of a reliable apartment security system are the presence of:

• magnetic contact sensor for opening the door;
• motion or glass break detectors;
• receiving and control central device.

An additional element is the use of a safety alarm button.

Self-installation of a security alarm system in an apartment is a rather complicated process that requires preliminary study of the legislative framework, the location of sensors and the installation of devices, so it is recommended to entrust this matter to professionals.

It is obvious that the security alarm system is designed to detect unauthorized entry of the intruder into the facility that is equipped with it. Conventionally, it can be divided into two parts:

• object (equipment installed at the protected object),
• console (equipment located on the centralized security console).

The main characteristic of any security system is its effectiveness. The following methods of ensuring it should be noted:

1. Reliability - the probability of failure-free operation, which is provided by the equipment manufacturer and the quality of installation.
2. Reliability of intrusion detection, achieved by minimizing false alarms (determined by the use of competent design solutions).
3. The probability of detecting an intruder. It is achieved by the completeness of blocking by technical means of vulnerabilities, the paths of the probable movement of the intruder.

In addition, to increase the effectiveness of the security alarm, the principle of boundary is used, as well as early detection tools. For example, blocking walls with vibration detectors makes it possible to detect an attempt to breach the wall before its final destruction.

Measures to increase the fortification of the object by engineering and technical means should not be neglected. These include metal doors, grilles, protective glazing. Of course, by "enclosing" the entire object in armor, the signaling can be abandoned. But we are talking about a reasonable combination of engineering and technical means and security equipment.

Let me explain with a specific example. With an external deaf metal shutter 10 mm thick, a criminal can be transported for half a night, but the alarm will only work after the window is broken.

As practice shows, after that, a few minutes are enough to penetrate the object, steal valuables and hide. The detention group will not physically have time to arrive at the scene of the crime. Access to a much weaker structure, installed on the inside of the premises, is possible only after a violation of the security alarm loop. 10-15 minutes spent on overcoming it significantly increase the chances of detention.

The psychological factor should also be taken into account - a competent criminal always evaluates the quality of the object's protection. If it is equipped properly, then the risk will simply not be justified.

ALARM SCHEME

It should be said right away that a typical scheme for constructing an intruder alarm system will be given here - something between structural and fundamental. Connection of specific devices and detectors is carried out according to the scheme given in their technical documentation. However, general principles for organizing a signaling loop exist and are described, for example, on this page.

So, the classic version of the burglar alarm circuit for a summer house, house or apartment is shown in Figure 1.

1. control device (panel),
2. power unit,
3. optoelectronic detectors,
4. acoustic detectors,
5. magnetic contact sensors,
6. sound and light alarms.

The alarm loop of the 1st security line (perimeter) blocks windows (for breaking - with acoustic, for opening - with magnetic contact detectors), as well as emergency exit doors, hatches. If necessary, vibration sensors can also be included (conditionally not shown in the diagram) to detect wall breaks.

The second frontier of the security system contains optoelectronic devices (volumetric, surface and beam operating principle). Instead of them or together, radio wave and ultrasonic detectors can be installed. Again, in order not to clutter up the diagram, I did not indicate them.

The entrance (working) door is connected separately. This is due to the fact that in order to prevent the alarm from triggering when the object is closed and opened, a response delay is set on this loop. If the arming - disarming of the equipment is carried out from the outside of the room, for example, with Touch Memory keys (position No. 7 on the connection diagram, then the front door can be connected to the perimeter of the object.

It is worth noting that for a small cottage or apartment, the above option is quite acceptable. However, for a private house with a large number of rooms and windows, it is better to break each security loop into several (Fig. 2).

This is explained by the following reasons:

• convenience of localization of the place of possible penetration,
• simplifying troubleshooting.

ALARM EQUIPMENT

The composition of the burglar alarm equipment includes at least:

• detectors;
• receiving and control devices;
• power supplies;
• annunciators;
• the object part of the notification transmission system (SPI).

Burglar alarm detectors are designed to detect unauthorized entry to a protected facility. This equipment differs in the principle of operation, respectively, in the purpose and ability to solve the problems of controlling the internal volume of premises, destroying various building structures, opening windows, doors, etc.

The next, no less important component of the equipment is the control panels that process the information received from the detectors and control other alarm devices. They are classified according to many different parameters, more about this is written.

The power supply performs two main functions:

• provides signaling equipment with the voltage necessary for its operation from the 220 V network;
• in the event of a power outage, it acts as a backup source.

Annunciators inform about the status of devices and detectors. They are acoustic, light and combined. Their information content can be different, for example, light indication units can simultaneously reflect the state of dozens of alarm loops, and sound ones can broadcast quite complex speech messages. However, the latter is more related to the equipment of fire systems.

SPI are used for console protection. For autonomous alarm systems, they are not needed. The type of this equipment is determined by the security company. The transmission of notices is carried out by wire or wireless. Radio channel and GSM systems are used more and more often. Apparently, in the near future they can take a leading position in the field of transmitting information about the state of security systems.

Installation of security alarm equipment.

If we talk about regulations, then the main document that determines the procedure for the installation and installation of technical means of security alarms is RD 78.145-93. This is a regulation of private security. On the one hand, if the alarm is not sent to the OBO remote control, then it can be neglected. On the other hand, this document is intended to ensure the reliability and completeness of blocking vulnerabilities. Thus, it can be useful in any case.

In addition, the technical passport of any security equipment contains general recommendations for its assembly and installation. As an additional source of information, the documentation for the detector or device can be very helpful. As for the connection diagram, here deviations from the manufacturer's recommended option are unacceptable.

SECURITY ALARM REQUIREMENTS

The main requirement for a security alarm is its reliability. It is achieved by a whole range of organizational and technical measures, namely:

• the most complete definition of places vulnerable to penetration into the object;
• a competent choice of technical solutions for their blocking;
• achieving maximum fault tolerance of the security alarm system.

The first issue should be resolved at the stages of drawing up the terms of reference and designing the system. Here an important role is played by the experience of the developer and his good knowledge of regulatory and technical documentation. Each object has its own characteristics, so it makes no sense to give correspondence recommendations here.

The second point implies the choice of equipment that is most appropriate in terms of its technical characteristics to the tasks solved in each specific case by the security alarm system. Often, reliability is increased by the simultaneous use of detectors with different operating principles, as an option, it is possible to use combined (combined) sensors.

Fault tolerance, by and large, implies high requirements for the time between failures of all components of the system. In addition, the quality of installation plays an important role here. Electrical contacts have always been the weak point of electrical circuits, and they tend to deteriorate over time. Therefore, proper maintenance is a prerequisite for the reliable operation of the security system.

There are two more points to note:

• exclusion of interference in the operation of the alarm by unauthorized persons in order to disable individual sensors or the system as a whole;
• the presence of the function of self-diagnostics of equipment for the timely detection of possible malfunctions.

The complex fulfillment of the above requirements can significantly increase the reliability and efficiency of the security alarm and its trouble-free operation for a long time.

A burglar alarm is a set of hardware and software designed to notify interested parties in an attempt of unauthorized entry into a protected area. At the moment, several types of burglar alarms are widely used, which differ significantly in performance and functional features.

Varieties

The main difference between alarm systems is the way the alarm is transmitted. There are the following types:

Autonomous system. In addition to standard detection devices, the room is equipped with sirens and strobe flashes. All external devices are connected to a single controller. In case of receiving an alarm signal from one of the detectors, the controller sends a command to activate the light and sound alarm. Depending on the settings, the alarm will be activated for 3-5 minutes. During this time, he will scare away the thief and attract the attention of neighbors, passers-by or law enforcement officials.

Wireless Standalone Alarm Kit

The system is connected to the security console. The control panel of such a system has a communication module that transmits information about unauthorized entry to the control panel of the security company. Transfers can be made in various ways:

• Through a telephone line;
• NPLS - a direct line of communication stretched between the protected object and the building where the guard is located;
• Wireless transmission of violation data can be carried out via a GSM modem using 900 or 1800 standards. The signal is transmitted by a simple phone call or by sending SMS messages to a pre-programmed list of telephone numbers.

The composition of the security alarm

Security alarm consists of the following elements:

The alarm sensors are the key devices of the system. The industry produces many models with different performance indicators.

Features of mounting a security alarm

For the effective functioning of the security alarm, the installation of all devices must be carried out in accordance with the standards of GOST R 50776-95 and installation guidelines: RD 78.145-93 and RD 78.36.003-2002.

Mounting the control unit

Installation of a central security alarm control unit of small and medium information capacity (can support from 1 to 5 loops) can be carried out outside a special room at a height of 2.2 m from the floor. If the installation is carried out in a special room, then 1.5 m is allowed. If the device is installed in a room with open access, then it must be placed in a metal cabinet with a lockable door. It is forbidden to install in cabinets made of combustible material or place it closer than 1 m from a heat source (heating battery, air conditioner, etc.). Fastening must be carried out securely, under the screw, through all 4 mounting holes.

Installation of cables and loops

Loops in the security alarm are electrical circuits that combine all the outputs of the actuators. The cable is connected to the central control unit. The alarm signal interrupts the circuit to the loop, which causes the control unit to generate a command in accordance with the inherent algorithm of actions - an alarm or a malfunction of the loop.

Installation of cables and loops is carried out with a single-core copper cable covered with polyethylene in a PVC sheath. In certain cases, to prevent electromagnetic interference, the cable is protected by a sheath made of aluminum laminated foil.

Mounting sensors

To maintain their operational characteristics, alarm detectors must be installed on fixed massive structures subject to minimal vibrations. Mounting is carried out on a bracket, which allows periodic inspection and, if necessary, maintenance. When installing the detectors, it is not recommended to expose the body of the device to excessive mechanical loads, shocks, or bend the wires in front of the terminal block.

The location of the motion detector in the room is strictly regulated. The optimal position will create the most effective overlap of the protected premises with a minimum of blind zones:

For large rooms with solid walls, it is recommended to set the detection zone, which slightly exceeds the parameters of the room. This effect is achieved by replacing the Fresnel lens and adjusting the radiation strength of the ultrasonic and microwave generators. At the same time, there should be no shading objects at the level of the detector installation in the room.

The use of IR detectors has certain limitations. It is unacceptable to place such devices if:

• The sensitive sensor is exposed to direct sunlight for a long time;
• Sharp sun glare or reflection of artificial light (headlights, etc.) falls on the sensor;
• The device is located near heat sources - convection heat flows will create false alarms;
• The appliance is located near natural or artificial ventilation niches or in the path of conditioned air flow.

Setting the panic button

Panic buttons are devices for manually activating an alarm. The installation location of a stationary panic button depends on its purpose. The fire and security alarm button is mounted in a conspicuous place within the direct access of the security guard. A hidden panic button is mounted mainly under the cashier's desk or in other places where an employee is supposed to retreat during an attack.

Any burglar alarm, regardless of the device and type of alert signal, is designed to inform the user about unauthorized entry into the facility. Detection of the presence of an undesirable person in the building is provided by the installation of sensors, and the notification system can be centralized or autonomous.

The system can transmit intrusion notifications in two ways - by sound and / or by means of light signals. In the first case, it is necessary to use sound annunciators (sirens, bells, and so on), in the second - light (LEDs or lamps).

In modern devices, instead of lamps and bells, more reliable and durable signaling devices on semiconductors or piezoelectric emitters are used. Such devices, among other things, are characterized by smaller dimensions and the possibility of fine tuning.

Other required outline elements include:

• intrusion or presence sensors;
• reception and control panels and devices (PKP);
• event data transmission equipment.

Information about intrusion into the protected object can be transmitted remotely, to the centralized security console or the owner's mobile phone. If this possibility is not provided (or the option is not used), we are talking about an autonomous burglar alarm system.

The latter option is extremely inefficient in operation and is not recommended for use. Its arrangement is justified only in the case of permanent presence of the controlling person in close proximity to the protected object.

Transmission of an intrusion signal to an object can be carried out in two ways - wired or wireless. Wired systems transmit relevant information over a dedicated or busy telephone line, depending on the owner's capabilities and proposed installation options.

The advantage of this type of signaling is a high-quality, guaranteed stable direct and feedback connection with the monitoring console, the possibility of constant monitoring of the communication channel.

Wireless alarms use the network of any cellular operator or a dedicated radio channel. When using GSM alarms, the most important thing is to ensure continuous monitoring of the presence of communication. Otherwise, it cannot be ruled out that information about the intruder simply will not be brought to the attention of the operator of the security console or the owner of the premises in time.

You can make sure that there is a connection by receiving a signal from the protected object or by sending a request from the centralized security console and receiving the system's response. Using the second option is more expensive, since it requires the presence of a transmitter and receiver in the GSM module. In addition, it is necessary to have a bidirectional communication channel.

The connection check can only be discrete: this means that the request is sent at more or less short, but still finite, intervals of time. The shorter these intervals, the more reliable the burglar alarm.

OPERATING PRINCIPLE OF THE ALARM

Of practical interest to the owner of the protected object is the object part of the alarm system installed in the building or premises. It is from its high-quality arrangement and functioning that the overall reliability of the system largely depends. The components of signaling equipment have been listed previously. Below will be discussed in more detail about the most commonly used - sensors.

The direct purpose of sensors or detectors is to detect unregulated penetration into a protected area. You can invade the room through a window or doorway, as well as through a gap made in the wall. Therefore, it is necessary to ensure the functioning of sensors that respond to all methods used by intruders.

Security alarm sensors (detectors) are used to detect:

• opening windows and doors;
• breaking through walls and ceilings;
• breaking glass structures;
• movement within the protected area.

In order for the information to be conveyed to the operator of the central console, it is necessary to convert the detected action into an electrical signal. For example, if the sensor responds to the sound of broken window glass, such a device is called acoustic (sound).

If an intruder breaks through a wall or tries to knock out a door, a vibration sensor will react to his actions, fixing blows to the building structure.

Relay contacts, digital signal generators and other modern technological solutions can be used as detector outputs. After the formation of the electrical signal, it is necessary to ensure its further processing. For this purpose, control panels and control panels are used. Further, the information is sent to the notification and transmission devices.

Signal transmission can be carried out both by wire and by means of GSM and radio channel devices. In most cases, wireless communication refers to the method of transmitting data over a radio channel.

VARIETIES OF SECURITY ALARM SYSTEMS

There are many principles for classifying the systems mentioned: by the presence or absence of a centralized security console, the types of sensors used, the use of wires and the number of communication lines. Depending on the method of information transmission, security equipment can be:

• wired;
• wireless.

The most familiar version for the end user is wired loops. For a long time they simply had no alternatives and, although they are now recognized as obsolete, they have a number of undeniable advantages.

The first of them is increased reliability, subject to conscientious installation and ensuring the integrity of the cables connecting the individual elements. The second is the low cost of parts and installation work.

In general, a wired system is great for installation in a small room or a separate building. A prerequisite for the functioning of the circuit is regular monitoring of the condition of the connecting cables.

As the name implies, in wireless versions, to ensure the interconnection of individual elements, instead of wires, a radio signal is used, broadcast over a dedicated channel or via GSM communication. The advantage of such a system is the absence of the need for construction and installation work.

Disadvantages include significantly higher prices for the equipment used and attenuation of the transmitted signal over distance. In addition, if there are strong electromagnetic fields in the alarm coverage area, it is impossible to guarantee high-quality communication.

The best option for arranging a security alarm is to create an address system. The method is applicable for both wired and wireless options. The principle of operation of the address signaling is to assign a unique identification number to each sensor. Thus, the alarm control panel can determine exactly which detector the alarm signal came from.

The main advantages of the addressable device are the ability to connect all sensors with one communication line and the low cost of installation work. Equipment for such circuits, on the contrary, costs a little more than for conventional ones. In general, address systems are the best option for the protection of large and medium-sized objects.

When choosing a security alarm system, it is necessary to focus on the technical characteristics of the premises, the manufacturer and the financial capabilities of the owner of the facility. It is best to entrust the installation and maintenance of the system to trusted certified organizations of the appropriate direction.

AUTOMATIC ALARM SYSTEMS

Since signal transmission between the elements of any circuit occurs without human intervention, any signaling can theoretically be called automatic. Currently, intelligent systems with a much higher level of automation are being actively developed.

It is extremely important that the alarm has the option of self-testing (automatic control) of operability. Such a possibility can be implemented in addressable devices, and for its operation a software add-on is required over the hardware component.

In addition, programmable systems have the following capabilities that are not available in hardware-only systems:

• integration of individual circuits into a single complex;
• differentiation of access rights of each operator;
• creation of complex scenarios of equipment operation.

No matter how modern the burglar alarm is, it is impossible to completely eliminate the risk of false alarms and the inconveniences associated with it. However, due to the possibility of a comprehensive analysis of the factors affecting the sensors, this probability can currently be minimized.

This allows you to reduce the cost of response (departure to the scene) and additional maintenance of the system, as well as create the most comfortable working conditions for the operator.

Security complexes of foreign and domestic production are presented on the market. Among the latter, the Orion system developed by NVP Bolid can be called the most successful development. This complex has a friendly, intuitive interface, a wide range of customizable functions and the ability to configure for specific purposes.

Uninvited guests, an increased crime situation, the threat of vandalism and other illegal actions - all this forces homeowners to take care of protecting their own home.
Optimal solution - organization of a security alarm system in the house.
In practice, even the simplest outdoor surveillance cameras or even their dummies of video cameras reduce the risk of unauthorized persons entering the territory.
However, an object can be made safe only by organizing an integrated system that includes not only video surveillance equipment, but also gas sensors, flame detectors, fire extinguishing and fire safety elements.
To decide on a certain type of system, it is necessary to take into account the specifics of the object.

Application home security alarm systems

A country cottage or a private house differs from apartments not only in location and design, but also in greater distance from neighbors.

In multi-story buildings, break-ins are more noticeable, which may cause neighbors to call law enforcement. And this is not to mention the electromagnetic lock at the entrance and the access video intercom, which minimize the risk of violations.

Remote alarm set for a country house

Private housing is deprived of such assistance, and therefore needs organizing an autonomous security alarm, which should be chosen depending on a number of features of a particular object:

• the total area of ​​the house and adjacent territory;
• number of inputs and outputs;
• distance from the nearest neighbors and the service area of ​​the private security company;
• house configuration: the presence of balconies, terraces, loggias;
• the presence of the site and buildings on it.

All this facilitates unauthorized entry and requires more attention to the organization of the alarm system for safe living in the house.

home security alarm structure

is a combined system consisting of a complex of various protection methods depending on the communication channel and connected to the loop. The system consists of sensors, a control panel (PKP) and actuators.

Sensors control a certain parameter: opening a door or window, movement in a certain area, breaking glass, unauthorized access to the territory, and so on. When triggered, the presence sensor transmits information to the control panel.

Reference: the main types of sensors respond to three parameters - opening, movement, breaking.

The former are distinguished by the magnetic-contact principle of operation and are installed on doors and windows, reacting to the slightest vibration.

Motion sensors (volumetric and infrared) control a certain area and signal movement, and break sensors are installed near windows and turn on when they are broken.

This device is a board in a special shield, which is connected to all sensors and when one of them is triggered, the device processes the signal and transmits them to the actuator.

The actuating device can be a light and sound element, or a voice message transmitter to a mobile phone or to a security company.

This whole process takes place within a short time to alert the owners and the security company of unauthorized access to the house.

GSM-alarm system for home KERUI IOS-Android

Depending on the communication channel, they can be wireless - security alarms work through the GSM network, and wired - they are laid along the site.

The systems themselves operate both from a 220V network and autonomously from a backup power supply, which ensures reliable operation even during power outages.

Reference: a loop is a chain of security detectors that are connected in series into a common system.

The principle of operation of the system is as follows: when movement or vibration occurs in a certain area, the sensor detects the change and is triggered. The control panel detects the change in the loop and determines the zone in which the movement occurred.

• light and sound alarm;
• landlord phone number;
• remote security posts.

The system is turned off using a special code that the owner sets. Ways to control the system - remote key fob, or a keyboard connected to the board.

Location

By location are classified as follows: perimeter security, approach surveillance, and indoor areas.

Perimeter security

Perimeter security alarm

It involves the installation of sensors on the territory of the facility that detect movement and warn the homeowner and the security company about it. The most effective system, since it allows you to prevent intruders from entering the house and issue it even before entering the territory.

Appropriate requirements are imposed on perimeter security systems: the possibility of hidden installation, the absence of “blind” zones, the exact following of all perimeter contours, the absence of interference, and resistance to climatic conditions.

Sensors in the burglar GSM alarm system Strazhnik MULTIZONE II

Vibrating. An electromagnetic microphone is used in the sensor cable, which generates a signal when vibrations occur. If necessary, you can listen to what is happening on the territory and make an appropriate decision. The sensors are suitable for walls and roofs, fixing tunnels and destroying fences. Used for both light and solid fences.

infrared. They can be active and passive, where the former emit invisible rays and detect movement, while the latter register changes in the thermal background and generate an alarm signal.

capacitive. They work due to the electromagnetic field, which causes an alarm when an outsider approaches. Structurally, it is an electrical circuit around the entire perimeter. Suitable for long and large areas.

radio wave. These are two parallel feeders installed from different ends of the perimeter. A current is passed through them, which creates a strong electromagnetic radiation. When an outsider enters the field, a corresponding signal is registered (see Radio channel security alarms).

Radio beam. They act in a similar way to radio wave devices, creating an electromagnetic field, only in an elliptical shape.

The above equipment allows you to create a reliable protection of the territory and prevent the intruder from entering the house.

Observation of approaches to the object

It includes sensors that are installed around the perimeter of the building and react to the slightest vibrations and movement.

At the same time, many of the sensors can control the territory located at a distance of 10-15 meters from the building.

Home security

Console	They are connected to a centralized security post and signal about strangers by a special rapid response team, which immediately leaves for the facility	Possibility of crime suppression and investigation in hot pursuit, high efficiency in combination with video surveillance from a central point
GSM (wireless)	Special sensors and a GSM module are installed at the facility, which transmits information in the form of SMS or voice messages to the homeowner. It is also controlled using the keyboard on a special panel or remote control. Batteries are used as a power source	The fastest notification of the homeowner about unauthorized access, the ability to promptly call law enforcement agencies to the site even when you are far from it, the absence of cable lines and simple installation, no need to extend the cable when reinstalling	There are devices that jam the GSM signal, so the system is weakly effective against experienced robbers, a complex process of setting up and pairing devices, the need for periodic replacement of batteries, restrictions on use in areas where there is no radio channel communication of the equipment (see Cellular Signal Amplifiers).
Telephone (wired)	It works in a similar way to a GSM alarm system: a special device sends voice messages and SMS to the homeowner's phone	Prompt response, greater security in comparison with GSM-alarm systems, high reliability and security of the object	Not very convenient operation and high complexity of installation, however, these shortcomings are compensated by high reliability and safety

The cost of a particular system depends on the area of ​​​​the territory and internal premises, the need to protect the environment, the type of alarm and the number of additional equipment.
