What is a Burglar Alarm for?
A burglar alarm is a system of electronic devices, the operation of the entire burglar alarm system is aimed at ensuring the safety of objects and people. The equipment that is used in burglar alarms is very diverse. Differences in the operation of burglar alarm equipment can be as follows - the principle of operation, functional difference, power supply conditions, and others. You can install a security alarm yourself. Another option is to contact a company that provides this kind of service. And although installing an alarm yourself is a more economical way, it is far from the most reliable.
The equipment that is present in the average signaling is divided into several groups. Peripheral equipment or sensors are monitoring devices that generate a signal in the event of an intrusion. Control panel - here you can set all kinds of settings for the correct and necessary operation of the system. Warning devices - speakers, light detectors, blocking devices.
Types of Alarm Systems
Security alarms, like other security equipment, are divided into different types and types. The alarms that hit the market today generally come in three types. The first type is autonomous alarm systems. This type is the most primitive. Possibility of autonomous signaling - to give an audible signal, notify others about the penetration of the object, violation of its integrity. Autonomous alarms are cheap and least reliable.
The next type of alarm is connected to the central console. A burglar alarm with this principle of operation compares favorably with an autonomous alarm. The difference lies in the fact that the danger signal is heard not by neighbors or bystanders, but by employees of a security company. Maintenance of such an alarm is more expensive than the previous type of alarm.
The third type of signaling combines the advantages of the first two types: low cost and providing the necessary level of security. Alarms with auto redial - at the moment, two options for such alarms have been developed: using a telephone line, using a GSM channel. Alarms provided in this way of communication are not subject to the risk of power failure. A danger alert is sent to the owner's phone in the form of a call or SMS. In some cases, the notification may come to the control panel of the security company, then the principle of operation is similar to the alarms that are connected to the control panel.
Security Alarm and Modern Technologies
Modern technologies are becoming more and more universal. Today, burglar alarms can serve not only to protect against intruders, but also to protect property and people in general. Most modern alarm systems provide for the integration of sensors into their mechanism that respond to fire, gas, flooding, etc. Such alarms are relevant for various incidents. New technologies - the Internet and mobile communications - can also be used for security needs. Moreover, modern means of communication facilitate the process of installing alarms.
