Сигнализация с автоматическим запуском является инновационным устройством, которое может заблаговременно и с определенного расстояния запускать двигатель. Сегодня такая функциональность привлекает большое количество водителей. Предварительный запуск мотора дает множество преимуществ. Например, появляется возможность заблаговременно прогревать двигатель, нагревать салон зимой или охлаждать его в летнее время. Все это улучшает комфорт эксплуатации автомобиля. В ближайшее время разработчики обещают создать машину, которая будет заводиться с помощью умных очков. Однако это только в будущем. В предложенной статье мы поговорим о том, what alarm with auto start is better, подробно расскажем о ее функциональных возможностях и специфике установки.

How to choose a car alarm

Approximate set alarm with auto start

The choice of signaling depends on the following factors:

• type of car engine (gasoline or diesel);
• type of gearbox (manual or automatic);
• engine start method (from a distance or automatically by a timer).

The alarm system with automatic start of the engine carries out the work thanks to preliminary installation of a certain mode. The number of such modes depends on the model of the selected device. At the same time, even the simplest alarms can start the engine at any time to the nearest second. More serious models allow you to start the engine at a certain temperature inside the cabin or outside, as well as in the case of lower voltage networks. All settings the car owner sets in advance.

Devices with remote switching are also very popular. With one touch of a button, you can start the engine from any floor and at any time. The radius of action is about 500 meters. Do not forget about this criteria when choosing a car alarm. Some devices of this kind are capable of operating at a distance of more than 2,000 meters, but the cost of such devices starts from $ 500. The price of an alarm is determined by its functional set and the perfection of operational characteristics.

It is necessary to take into account the fact that devices with remote and automatic switching on have additional settings that significantly increase the number of launch methods. A simple alarm system will cost 120-200 dollars, and more advanced will cost 200-350 dollars. These are approximate prices and they are more dependent on the manufacturer.

Main selection criteria

Some models of alarm systems can be controlled from the application installed in the smartphone

In order to finally understand which alarm with auto start should be chosen, special attention should be paid to the following points:

• functional set of the device;
• alarm signal coding method;
• equipment.

It may seem that with additional functions and a complete set everything is extremely simple, but this is not quite so. A large set of equipment and versatility complicate the installation of the device, which leads to additional costs.

There is such an aspect as feedback. It is carried out through the use of special mechanisms through the sending and receiving of the signal. Such devices are:

• special sensors;
• cheese;
• GSM module or keychain.

The key fob is equipped with a display, which displays all the information about the current state of the car.

Most alarms with auto start are equipped with a remote control with a display

The signal in the device with automatic start is sent through the use of radio transmitters or GSM modules. Radio signals are encoded in dynamic or conversational mode. GSM modules have a more secure signal transmission system, which significantly reduces the likelihood of car theft. Additional advantages of this mechanism are the ability to control the car through a mobile phone and the signal coding with a special digital code. The disadvantage may be a weak coverage of a certain zone by the mobile operator.

The advantage of radio transmitters with a dynamic signal coding system is an affordable price. Negative sides: low security and the ability to read a signal with a special device (grabber).

The advantage of radio transmitters with interactive coding is the automatic change of the code after a certain period of time, which protects the system from decoding and ensures good security. The disadvantage is the relatively high cost of signaling and a small range of the signal.

Installation and operation

It is better to entrust the installation of alarm with auto start to professionals.

Installation of an alarm with automatic start should be entrusted to a qualified technician. In fact, this is due to many factors. Modern cars often have their own anti-theft system, for example, immobilizer. And if there is a desire to additionally equip the machine with an engine starting system in advance, then, most likely, certain difficulties will arise.

The compatibility of a standard alarm and a new one, with an autostart function, can be difficult. Only an experienced master can solve this problem. If an immobilizer is installed, it will be necessary to equip the system with a bypass chip module (digital key) or to get out of the situation in another way.

Usually, the bypass module completely solves the problem of compatibility of the staff immobilizer and alarm with auto start. It allows you to automatically turn on the engine in all modes and does not conflict with the security system. In this case, the system itself automatically turn on the motor does not provide protective functions.

When searching for the answer to the question, what kind of alarm is better, in no case do not forget that autostart reduces the anti-theft properties of a regular security system, although it creates a really high comfort of using a car. Today, such alarms are sold in almost any auto shop. Therefore, it makes sense to completely replace the outdated system with a better, more modern and improved model, while maintaining a decent degree of protection.

Additional functions

A popular feature for auto-alarm alarms is the turbo timer.

Alarms with automatic start can be additionally equipped with the following elements:

• Turbo timer Alarm with integrated turbo timer installed in cars with a turbocharged engine. The device is mounted in a place protected from prying eyes. Usually choose a niche under the torpedo. The principle of operation of the turbo timer is as follows. When the car is stopped and the ignition is turned off, the engine continues its work for the amount of time that was originally set in the settings. After a set period of time, the alarm turns on and only after that the motor stalls. Such an approach favorably affects the engine's service life, especially when the engine overheats and cannot immediately be jammed. The engine will operate at low revs, cool gradually and then shut off.
• Anti-Hi-Jack. This anti-robbery feature is provided today in almost all car alarms. It allows you to simply lock the ignition system on the car by simply pressing a button on the key fob. And it turns out that it is impossible to start the car without the key fob button. Anti-robbery mode is activated instantly when the door is closed or opened, or when you start or shut down the engine.

Finally it is worth noting that the best reliability and excellent functionality of the most expensive alarm system with automatic start can be spoiled by poor-quality installation of the system. Therefore, we recommend using the services of true professionals.
