Alarms, for cars: types and functions

Car alarms are a fundamental system for protecting a car from theft and acts of vandalism.. Although a large number of models have an alarm installed by the manufacturer, nevertheless, there are others. In this case, you can install a third-party security system.

A car alarm is a system that consists of a number of sensors strategically important in a car to detect movements or abnormal activities around or inside the car. When a potential hazard is detected, the system issues alarms or warnings to try to prevent the threat.

Alarm History for Cars

The invention of the bell was made by the American August Russell Pope, who, in 1853, patented the electromagnetic system, it consisted in the fact that when he closed the electric circuit, the vibration caused by several magnets transmitted vibrations to the hammer, which knocked on a bell made of brass.

However, many years passed until 1920, when the first audible car alarm was developed and integrated into the car, the use of which lasted for many years. Devices were installed on the front axle of the car, and activated with a key.

Alarm types for cars

There are many types of car alarms, which are divided into categories, for various reasons.

First, the depending on the reaction of the car, due to the threat Two types of alarm can be distinguished, for cars:

• Passive systems. Systems of this type only emit acoustic signals and light signals in order to deter or prevent theft.
• Active systems. This type of alarm for cars, not only emits sound and / or light signals, but also, automatically, activates a number of other functions in the car. Among them are notifications of the owner or security service, blocking of the steering wheel, wheels, doors or starter, etc.

On the other hand, in accordance with the system response modeThe following alarm options for cars exist:

• Volumetric sensor. Detects abnormal contacts with the vehicle.
• Perimeter sensor. Detects abnormal movements around the car.

Finally, the depending on system technology, distinguish the following types of signaling for cars (it should be borne in mind that these systems can be combined):

• Electronic alarm. This system is based on a control unit, which, after receiving a signal from sensors installed in the car, gives an answer. These alarm models for cars have the ability to work in the Republic of Kazakhstan. That is, using the remote control, it is possible to turn the alarm on or off. More advanced ones allow you to give out signals in the form of vibration.
• GPS Alarm. This is currently the most advanced system. Allows you to determine the location of the car at any time and control if it changes its position.
• Alarm without installation. These are portable systems that are located in the strategic areas of the car and are connected to the power supply system to allow the inclusion of sound and light signals in case of a threat.

Car Alarm Features

The security functions that the car alarm can offer will be directly tied to its computer. Some features include the following:

• Connection between car and user. Thanks to the application installed on smartphone, the user can connect to the alarm system, which allows you to check the security status of the vehicle (for example, allows you to see if any doors or windows were open).
• GPS signal. As mentioned above, in the conditions of a car alarm, equipped with GPS alarms allow you to control the exact position of the car at any time. This is one of the options most in demand in cars of the latest generation, because, in the event of a possible theft, the system also facilitates the return of the car.
• Hearing system. Some alarm systems include microphones that allow the user to hear sounds inside the cabin at any time from a smartphone.
• Two way communicationb. This function allows the user to connect to the car speaker in order to transmit voice messages.
• Acoustic signals and sound. These are the basic protection functions of any car alarm system.
• Car lock. This feature seems to be more valuable in terms of security. Locking the car makes it impossible to move, whether due to the blocking of the steering wheel, wheels, doors or starter.
• Connection to PBX Security. If there is this function, the car, being in the risk zone, throws a notification of the telephone exchange, which mobilizes the police, providing them with the coordinates of the GPS position of the car. This feature includes the payment of a monthly fee.

Conclusion

The technology of alarm systems has changed significantly in the last decade, in particular, thanks to the development of GPS systems and the wireless transfer of information between the car and the user, which provide remote control and control of the car.

Buying a car involves financial costs, therefore, every day, more and more drivers value their investments and try to ensure their safety.
