Before deciding which alarm system is better, consider what functions it performs and its types. The standard set of car alarm functions includes: triggering to open doors, hood and trunk, engine blocking, triggering for shock. There may also be additional functions: the ability to monitor the condition of the car at a distance, display information on the screen of a key fob or other mobile device, program functions and other parameters of the car alarm, auto start the engine, and more. Car alarms are: analog (AAS) and digital (DAC).
Analog (wired) car alarms are a complex system that includes sensors, blocks, wires and other devices, the interaction and operation of which is organized by the central control unit (CBU). The alarm system can be monoblock or multiblock. The control unit should normally be located inside the vehicle.
Car alarms can be provided with two-way communication with a pager mounted in a key fob. Depending on the availability of this function, alarms are divided into two-way and one-way. If we talk about “Which alarm is better?”, Then it can be clearly stated that two-way is more popular. Also analog car alarms can be equipped with an additional function of automatic remote start of the engine.
Digital car alarms are a number of functionalities to ensure vehicle safety, which are combined into a single complex. The operation of such a security complex is controlled on the basis of a digital blocking relay. The digital relay code can be constant or variable. DACs can be either wired or wireless. Which alarm is better in this case? More reliable among the existing security systems are wireless CACs.
In addition to the basic functions, digital security systems (CSC) have in their stock a number of additional functions that fundamentally change the idea of the alarm system. The main feature of the security complex is that information can be displayed on a mobile phone, which turns into a control panel. The owner of the car, having installed a special application for the phone, can not only control the status of the CSC, but also manage its work: make settings, set and disarm, turn on the engine lock or start it, and much more.
In addition, the CSC may include the following additional functions:
- identification of the owner of the car by phone and when it approaches automatically turn off the door lock;
- reporting of disturbing events by voice or via SMS;
- set a PIN code to exclude access by unauthorized persons to the program;
- battery charge control;
- An intelligent security organization that avoids false alarms;
- the ability to track the location of the car;
- the ability to modernize management programs and security functions;
- other functions.
After all of the above, the question “Which alarm is better?” "You can answer this way, the most reliable and functional are digital security systems. However, this statement may be appropriate for owners of expensive and elite foreign cars who can afford it. It is no secret that the security complex is not cheap. It would be absurd to assume that the owner of the Lada will think "what alarm with auto start to choose?"
Car alarms, which the owner of the car is to choose, must correspond to the class of the car and financial capabilities, taking into account the storage and operating conditions.
