Any real estate owner seeks to protect his property, whether it be a house, garage or something else. Time passed, the ways of protection changed. Today, a variety of security systems are very popular, which are able to notify the owner or security organization about the appearance of uninvited guests. Such systems have become necessary, in particular, for entrepreneurs who install them at their commercial facilities.
Security alarm (hereinafter we will use the abbreviation of the OS) – this is a set of various technical means that ensure the detection of unauthorized penetration into the room. The system without fail reports attempts to such an invasion to the owner of the territory and law enforcement agencies or security enterprises.
There are several ways to deliver messages about the invasion. This is the central security point, a telephone informant (when using a telephone line), GSM module (used by a GSM telephone), as well as an Ether-module if there is a local computing network.

The security market offers three types of alarm: autonomous, automatic and remote control.
Autonomous OS with unauthorized penetration into the room stunes the “visits” with a loud sound with a capacity of 120 decibels. She has serious shortcomings: real criminals can always disable the alarm using mechanical exposure, in addition, it is characterized by frequent false operation. Such an OS is effective only if there is a security point in the house, which by the indicator learns about the hacking.
Valin to all the phone numbers entered in advance lies at the heart of the automatic security system. When the owner receives information on the phone, he decides what to do – protect the property on his own or contact the relevant authorities. However, such an alarm is easy to get around if you cut the telephone wire.
The most reliable and most expensive type of security systems is the alarm bonded to the centralized security panel. When a signal about an attempt to introduce comes to the remote control, a group of law enforcement officers or private security company (PFI) is sent to the facility, depending on who is engaged in the protection of this premises. Employees go to the place and if the connection is turned off, which is also reflected on the remote control. When using this type of OS, it is impossible uncontrolled penetration into the room, since all blocks and unlocks are recorded. In order for the remote alarm to be installed, the owner of the premises signs the contract and pays this service monthly.
