Burglar alarm.

Security alarm system - a complex of electronic security devices, which provides protection against the encroachments of the object, by notifying the owner or law enforcement. At the moment, two main types of relevant signaling: 1) alarm system with call protection or vnevedomstennoy CHOP, with monthly payment, 2) GSM-alarm, when an alarm alerts the owner by SMS - message or call to the mobile phone.

The alarm system consists of a control device (with GSM-module or not) and a variety of sensors, depending on the object to capture the offender, as the system includes: uninterruptible power supply with battery and cable for alarm systems (KSPV, KSPVG) . Control and security device can be wired - wired connection to the sensor, and Wi-Fi - wireless connection to the sensor by means of a radio signal (power wire). Radioohranoy management can be done via wireless remote controls. The tester displays the current alarm mode ("Attention", "Alarm", "Descent"), as well as with key Touch Memory or put SMS \ disarmed.


Security sensors (detectors) can be of different types, depending on the task assigned to them, respectively, they used one or other intrusion detection technology in a protected area:

* Infrared Detectors (volumetric)
* Magnetic Sensor
* Glass break
* Vibration Detectors
* Combined Detectors
* Ultrasonic Detectors

Sensors for burglar alarms.

Infrared detector - this immunity, which responds to changes in the level of heat emission when the person moves, intended to protect the perimeter areas, corridors and areas in the controlled area. IR sensors are the most common among all other detectors, this contributes to a simple and reliable method for detecting a large area of ​​the protected object, as well as low cost and simplicity of operation. Typically, the angle covered area of ​​about 90 °, reach up to 25 meters. Some models allow you to ignore pets weighing up to 20 kg, which allows to use this type of sensors in homes with pets. IR detectors are often used with other security sensors.


Magnetic detector (magnetic contact) - is used to control the opening of doors and windows of the protected premises. The principle of operation is very magnetic contact (reed) is based on the interaction of magnets, one of which is mounted on a fixed support, and the other - on the mobile frame window or door. Thus control the outer perimeter of the protected area, and magnetic contacts can be installed on the gate for additional security vehicle access to the territory. This type of sensor is the simplest and cheapest of all, but it has some disadvantages, such as broken, but the vent window or door. Reed switches are used only as part of a complete system of protection and must be used together with other types of security sensors.

Glass break detector (acoustic sensor) - responds to sound breaking glass. Stored in the memory of the detector variations sound breaking various glasses. Built-in microprocessor analyzes the sound spectrum and compared the sound of the recorded data, which eliminates false alarms. Range of security glass break detector is about 12 meters, the angle of response of approximately 170 °. This system protects against rough entry to the protected area. Acoustic detectors are usually used in conjunction with infrared sensors to improve the reliability of the security system.

Vibration sensors - designed to detect the intentional destruction of concrete, brick and wood, as well as for the detection of metal cracking safes. Vibration detectors react to the vibration on the surface of the material, the coverage area of ​​a concrete, brick and wood surface is 12 m 2 on a metal surface - up to 6 m 2. Modern vibration sensors contain a microprocessor to extend the range of detectable effects (gas cutting, elektrorezhuschee, electric arc), and to screen out extraneous vibrations.

Combined detector - this is the IR detector and glass break sensor, made in a single package. Dual detectors are designed to more accurately detect the offender, eliminating "dead zones" are also convenient and installation, as there is no need to set two different alarms. Typically, these sensors are shielded from radio frequency emissions and noise as well as the direct and reflected light.

Ultrasonic sensors - designed to detect a violator in a protected area indoors. Ultrasonic detectors react to movement under perturbation fields of elastic waves of ultrasonic range. Ultrasonic detectors are used in rooms with acoustic noise level no more than 60 dB. And on at least 2x2 m 2 (corridor, hot shop). This type of sensor is often used with other detectors.

Radiation detectors (IR barriers) - is active infrared detectors DIP consisting of a transmitter and receiver optical radiation, designed to protect the perimeter of the protected object. Used to capture the offender at a distance, sensors are installed at a distance of about 60 meters from each other, the angle adjustment -10 ° vertically and 90 ° horizontally. Radiation detectors are the most popular solution for perimeter protection systems and work in all weather conditions. In modern sensors is possible to ignore the birds, animals, and falling leaves.

Capacitive sensors - this detector to protect the safe and high-value items, the sensor responds to the approach or touch a metal object. The sensitivity of the capacitive detector is set to 20 cm These sensors are used rarely, mostly in museums, for the protection of exhibits.

Sensors to detect directional diagram - is an infrared sensor mounted lens. Type of lens is determined by the purpose of the detector. The device works on the principle of analysis and control of thermal radiation. There are several types of detectors with directional diagram of detection: 1) curtains 2) curtain 3) corridor. This type of sensor is simple to install, and these detectors are resistant to false alarms.

Setting the alarm requires high professional skills of the staff, so the installation of the alarm system should be performed only by qualified personnel. LLC "Phoenix" - are staffed several teams with highly skilled engineers and installers. The installation process begins with the alarm site survey by our experts. Vulnerable areas of the object studied, as well as select the best equipment that will provide the maximum protection of the object at a low material costs, always listens to customers.

Further, based on the survey instrument and regulations, our engineers and designers of the project are set alarm. After project approval by the parties, to supply equipment, and then installing and commissioning.

Modern alarm system, when equipped with specialized sensors, can perform additional functions to detect and address the various domestic problems, such as a gas leak, water leak, etc. Also, this alarm system can monitor power supply, temperature, and control the various processes.
Modern means of protection should be installed in conjunction with CCTV, which greatly enhances the functionality of the system as a whole, increase security, and reduce the cost of the entire project. Centralized control of the system, allows more rapid decisions and simplify life itself to the customer. User will be able to monitor all processes through surveillance system as the object itself, or remotely, via the internet or mobile phone.

Also, a security system, you can integrate access control, and accounting staff time at the company. Thus, combining all of the complex multi-function security system, the end user will receive the full amount of information, including video, of what is happening at the site at the moment, or at any time. This provides maximum protection and property. Integrated security systems, control, and surveillance can be set to any object: private house, apartment, office or business, "Security and safety" will help choose the best solution for you.

Modes of transmission alarm.
To transmit alarm alarm system can be equipped with equipment such as radio transmitters, dialer, GSM-module.
Radio transmitter sends an alarm signal using radio. This method is quite versatile, but requires special permission for radio frequency. And the range of the transmitters is limited terrain and height of the receiving antenna. Moreover, the equipment is quite expensive and sensitive to noise.

Auto dialer using a wired phone line, generate alarms. It transmits coded tone or previously programmed to record numbers in it. This is the safest and cheapest option. But it does have drawbacks. Phone line, unfortunately, is not everywhere, and bring it down pretty easy.

With the GSM-module can generate alarms via short sms-messages using GSM mobile operator channel. The method is simple, but not very reliable. How long have you been waiting for SMS in the New Year? And mobile operators are failures, moreover, not in one rate plan, you will not see the guaranteed delivery time SMS.

Recently, with the development of technologies, methods of transmission alarm also rank as the Internet. With these features, many security firms offer overlapping channels. This increases the cost of the system, but safety, like art, requires sacrifice. The choice is still yours.

Control room alarm system includes a full hour control room and everything that happens in it. On the panel is a permanent record of all the events in a secured facility with fixing a precise time.
