18 best car alarms

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

Car alarm is an integral part of car attributes, more relevant than ever in our time. The problem of car theft is very directly dependent on the weakness of the standard security systems, which at best block the start of the engine, and at worst – only give an alarm.

The current level of development of alarms has reached the point that, under the guise of an ordinary 'box' and connectors, we are being sold whole security complexes that can not only control the safety of the car and prevent unauthorized access attempts, but also control individual systems: door locks, power windows, interior heating regulators, and even engines (ensuring it starts and warms up). Having touched on this topic, the editors and experts of the magazine have selected for you 18 of the best car alarms, which have been divided into logical thematic categories. The following were taken as criteria for the selection of products in the rating:

1. user reviews (their number and content);
2. technical characteristics and capabilities;
3. expert opinions on the course of tests and independent studies.

How to choose a car alarm

Choosing a security system for a car is a matter that requires mandatory preliminary preparation, since the theory that is valid for ordinary consumables and even detection / video recording devices plays absolutely no role here. In this regard, experts and the editors of the journal recommend paying attention to the following points:

Validation system. The governing body that controls the user's right of access to the vehicle interior. At the initial stage of the development of alarms, validation took place by sending a radio command from the remote control (by pressing a button), but modern security standards require the use of more advanced methods, which are much more difficult to get around. So, it is desirable that the central unit reacts to the presence of a special label from the driver, or requires a preset PIN-code from the basic car buttons. The top of perfection is a combination of several methods at once, in order to avoid various unpleasant situations (loss of a key, tag or forgetting an access code).

Radio communication protocol. A parameter showing at what frequency is receiving or receiving / transmitting data between the radio communication control body and the central unit. The systems developed now use the frequencies of 868 MHz or 2.4 GHz with a dynamic cipher of the communication channel. They completely exclude the possibility of hacking by using code grabbers. In contrast to the outdated 433 MHz band, for which an intelligent hacking algorithm has long been successfully selected.

Remote engine start. An option that is present in almost all modern car alarms, regardless of their price segment. There are two subtleties to keep in mind:

1. firstly, such systems show low efficiency in diesel engines due to their low heating rate at idle;
2. secondly, if the security system is not equipped with telematics, then control of the function will be available only within the radius of the radio reception.

The presence of a telematic system. This 'trick' came to the segment of car alarms straight from the market of tracking devices, and became, in fact, a breakthrough in the field of remote control. Thanks to geolocation via GPS / GLONASS and GSM networks, manufacturers allow owners to use tracking services, while simultaneously being able to track the status of individual modules. In particular, this is how the eternal problem of limited radio signal coverage was solved, and a full-fledged auto start of the engine from a long distance became available.

Geolocation. In general, an optional function for budget systems that has a great impact on the operation of advanced systems. As a rule, for the sake of understating the cost, manufacturers go to the trick by installing low-current geo-position sensors instead of GPS modules, using cellular network protocols.

Extensive reasons for triggering. A very subjective sign of assessing the quality of the security system, which should include as much as possible. Indeed, it is much better if the alarm responds not only to opening doors, hood or trunk, but also to impacts and even tilting of the car (for example, jacking up, towing or loading onto a tow truck).

Availability of a digital interface. Analog circuits for connecting the alarm control unit are not suitable for all modern cars, since their systems are a rather complex set of interactions and restrictions. In this case, the CAN interface (LIN), which serves as a kind of adapter between the main unit and the digital bus, can ensure efficiency.

The best inexpensive car alarms

StarLine A63 ECO

Car alarm rating: 4.9

Another product of the StarLine company, which has the absolute majority of positive reviews from the consumer segment. In addition to the fact that in its standard form, the A63 ECO offers quite wide operational capabilities, its functionality can be significantly expanded (although in this case the cost will go beyond the budget).

At the start, in addition to the central control unit with a standard connector, there are shock and tilt sensors, which sensitively, but without fanaticism, react to certain threshold values ​​of the shock load and changes in spatial position. The key fob and the unit support communication at a distance of up to 2000 meters, which is a good result for standard budget car alarms. Out of the box, there is an automatic engine start function and an immobilizer, however, only with unlocking via a key.

But as additions to StarLine A63 ECO, there are already more advanced chips, such as a universal CAN interface, a GSM module and a satellite communication sensor with an antenna. When installing this equipment, the cost will go boldly beyond 15 thousand rubles … however, the competitive environment of the modern market dictates its own rules for everyone.

Advantages

• an abundance of additional options and presets;
• flexible system of system analysis and engine startup;
• connection at a distance of up to 2 kilometers, dynamic code for channel encryption;
• quite low price of a standard alarm system.

disadvantages

• not found.

TOMAHAWK 9.9

Car alarm rating: 4.8

Having become a fairly ancient car security system, the Tomahawk 9.9 has not lost its charm, for which it naturally won the second place in the ranking of the best. The basis of its success is in many respects precisely the wide audience that appreciated the modest functionality that this device represents. Equipped with a standard siren-horn, the signaling device communicates with the control device at a frequency of 868 MHz and is encrypted using a dynamic code.

In view of the standard set of functions in the Tomahawk 9.9 car alarms, one can only highlight support for automatic engine start with flexibly configurable activation parameters. The key fob calmly picks up the signal at a distance of up to 1000 meters, which, in principle, is enough for control from the balcony. Yes, there are no additional connectors and interfaces here, but they, in fact, are not required: the alarm fits perfectly into its price range, providing consumers with more than reliable and high-quality services.

Advantages

• low system cost;
• has the required minimum of functions and features to maintain stable and reliable system management;
• the presence of dynamic coding of the signal over the communication line;
• signal reception / transmission distance is 1 kilometer.

disadvantages

• very modest functionality.

Scher-khan magicar 5

Car alarm rating: 4.7

A true classic among vehicle security systems, it allows you to control the central unit at distances of up to 1500 meters. Uses dual access function for intelligent tamper protection. How it works: two PIN codes are set, which are installed on the key and on the key fob. In case of loss of one of these elements or two elements in the aggregate, the system will ask for a PIN (1 – for a key, 2 – for a key fob). In addition, there is an addition with JackStop remote engine blocking, which allows you to forcibly turn off the engine after theft … and block the robber inside.

Like all advanced alarms of the Scher-Khan line, Magicar 5 is capable and well implemented of monitoring the key parameters of the engine, interior climate and battery charging. With the help of the built-in selector, the user can always set the automatic start of the engine upon reaching one control parameter: for example, when it comes to a drop in the ambient temperature, the battery charge is below 11.5 volts (the engine is switched on to operate the generator), or in order to simply heat the passenger compartment before trip. This is a very competent representative of inexpensive car security systems, worthy of one of the leading places in the rating of the best.

Advantages

• access to the car in case of a lost key or key fob can be restored using PIN codes;
• supports autostart for several control parameters;
• fully adapted to domestic operating conditions;
• abounds in standard equipment (CAN interface, GSM module, etc.).

disadvantages

• not found.

Niteo LX-10

Car alarm rating: 4.6

The fourth line of the rating is assigned to an extremely cheap solution to car safety problems without any claims for leadership or unique performance characteristics. Niteo LX-10 is a one-way communication system that has a simple dynamic protection against scanning (code grabbing), honestly performing all the scope of functions inherent in it. The range of the standard remote control here is no more than 50 meters – compared to the long-range responsiveness of the Alligator C-200, this is simply nothing. There is a built-in immobilizer, though without the starter blocking function – but for such a low price it will do.

As for the service functions, the Niteo LX-10 car alarm should be praised for them: there is a side window closer, door locking for the duration of the trip, as well as a small 'handful' of modes: 'Panic', 'Vehicle search' and 'Polite backlight'. Among the security functions, one can single out Anti-Hi-Jack, which works properly regardless of the testing conditions, security when the engine is running and the possibility of its silent setting.

Advantages

• very low purchase price;
• excellent functionality for a budget model;
• correct operation of all prescribed functions without exception;
• there is a dynamic encryption code.

disadvantages

• no super-options and interfaces are provided.

Alligator C-200

Car alarm rating: 4.5

Despite the low market value, the Alligator C-200 car alarm is positioned as a full-fledged premium complex for the implementation of car safety control and remote control functions. One of the main advantages of this signaling is the range of dialogue communication: according to some data, it is up to 2500 meters, while users claim about 3000 meters, however, without a large number of jamming elements.

The radio communication between the central unit and the pager is implemented here at 868 MHz, and is protected by dynamic BACS Dialog SST encryption. Manufacturers also boast of introducing an immobilizer with an additional engine blocking, but there is nothing to be surprised at for a long time. In general, the whole range of features of the Alligator C-200 is limited to this list: you can add, perhaps, a remote start of the engine by timer, calendar or fixing the minimum allowable temperature. The rest of the 'architecture' has been familiar for a long time and is of little value in our review.

Advantages

• a proprietary system for encrypting data transmitted over the 868 MHz channel was used;
• range of mutual communication (up to 3 kilometers);
• availability of the engine autostart function;
• optional ability to connect CAN- and GSM-module.

disadvantages

• optional add-ons are expensive.

Sheriff ZX-750 PRO

Car alarm rating: 4.4

The Sheriff ZX-750 PRO car alarm is a fairly standard model of a security system that uses a dynamic communication channel and the principles of control from an interactive pager equipped with a LCD display. It is one of the most frequent user choices in terms of cost characteristics, since the set of functions allows us to talk about the fact of an optimal and profitable purchase. Here, as in all modern systems, the ability to automatically start the engine for preheating is implemented, which is especially useful in winter.

In addition, the Sheriff ZX-750 PRO alarm system can boast a system of intelligent bypassing fault zones while maintaining the health of the remaining units and modules. An important nuance, according to experts, is a large number of optional add-ons such as the HP-type blocking relay or R350 / R450. But here the situation is rather twofold than purely positive. Yes, expanding the capabilities of one device is always cool, but do not forget that all additional acquisitions require serious expenses. And this kind of customer engagement policy can already take the device out of the budget … so you need to think twice about whether you need a system with 'truncated' capabilities.

Advantages

• absolute predominance of useful functions (there is nothing superfluous);
• there is an automatic engine start system;
• the function of a passive immobilizer is implemented;
• two-button door unlocking.

disadvantages

• optional add-ons require extra expenses (although in everyday life you can do without them).

Best Auto Start Alarm

STARLINE A93 CAN + LIN

Car alarm rating: 4.9

Inexpensive integrated security system that implements all the necessary set of functions to ensure the complete safety of the vehicle. Supports communication at a distance of up to 2000 meters, encrypting the channel with a dynamic code. It works at temperatures from -50 to +85 degrees Celsius, thanks to which it feels great in the harsh climatic zones of Russia. The central unit receives information from key fobs (included), a standard key (Slave mode), and can optionally be used to control a smartphone if the add-on includes a GSM module.

Among the service functions of StarLine A93, one can single out the ability to start the engine automatically (by temperature, calendar or interval setting), automatic glass adjustment to the extreme position, as well as search for a car for especially forgetful people during rush hour. The only nuance of the control unit is its rather large dimensions, which prevents its installation in some zones. However, this will not be a big problem for professionals. As a final plus, we highlight the presence of a CAN and LIN interface, which add versatility to a budget device.

Advantages

• optimal ratio of cost and quality;
• from the add-ons, you will only need to purchase a GSM module, with which you can control the alarm from your smartphone;
• excellent operational conditions (maximally adapted to work in the climatic conditions of Russia);
• support for engine autostart according to specified modes;
• the range is 2 kilometers.

disadvantages

• not found.

Pandora DXL 3945

Car alarm rating: 4.8

One step away from the leading line of the rating, a representative of Pandora stopped – a premium security complex with a contactless tag, a standard key (and a keyless immobilizer system), GSM modules and an optional GPS / GLONASS system connection. Like other representatives of the model range, the DXL 3945 allows you to work with a huge list of individual devices: from the standard D-705 key fob and a smartphone to the Pandora RW-04 smart watch, purchased for an additional fee.

Compact in itself, the central unit of the device can be placed anywhere without fear of disrupting the stability of signal reception from the satellite – in addition, the engineers did not fail and equipped the system with all universal CAN interfaces in order to provide the ability to interface the unit with buses on any model and brand of car . In addition to the standard set of already full-fledged functions, the Pandora DXL 3945 can undergo a comprehensive upgrade: to enhance the protection, the alarm can be retrofitted with the RR-102 blocking relay, the RHM-06 engine compartment lock control module and the NAV-035 GPS antenna to implement the same satellite surveillance system.

Advantages

• ample opportunities for system modernization;
• the presence of a contactless tag for keyless bypass of the immobilizer;
• convenient alarm control system: via a smart watch, smartphone or standard key fob;
• versatility.

disadvantages

• not found.

Tomahawk TZ-9010

Car alarm rating: 4.7

The ergonomic integrated security system of the Tomahawk TZ-9010 car has even more functions than the Scher-Khan Logicar A described below. We will not be able to cover all of them in the format of our rating, but we will say about the most important ones. Perhaps one of these is the implemented system for bypassing the faulty zone, in which the connection of the main control unit with the faulty sensor is broken without affecting the operation of other elements. This is very important both when trying to force a break in and when spontaneous damage.

A huge role in maintaining the safety of the Tomahawk TZ-9010 is assigned to the self-diagnosis system, in which the system at the signal level checks the tightness of closing the door locks, the trunk, as well as the height of the windows. There is a two-button unlock function: a single press will cause only the driver's door to open, while a second press will unlock the passenger doors. And, of course, let's not forget to note the possibility of autostarting the engine with control of its temperature parameters and climate inside the cabin. By adding here reliable dynamic code protection and an abundance of alarm modes, we will get an excellent security system for 100% safety of your car.

Advantages

• quite convenient keychain with display of the required metrics;
• engine autostart system with the ability to change operating modes and measure its temperature;
• availability of a system for bypassing faulty zones;
• self-diagnosis of the module for tight closing of doors, trunk and side windows.

disadvantages

• not found.

Scher-Khan Logicar A

Car alarm rating: 4.6

A worthy representative of the Scher-Khan Logicar signaling series, providing the ability to receive / transmit a signal at 1500 meters. The A-version uses the unique MAGIC CODE ™ PRO 2 encryption system, developed and modified directly by the manufacturers themselves. They, in turn, give a guarantee for the protection of transmitted data, as well as for the device itself (for 5 years).

A very pleasant fact for car owners is that the Scher-Khan Logicar A car alarm is fully adapted to operation in the Russian climate – the temperature range of its operation is from -85 to +50 degrees Celsius. As is the case with all models in this rating category, this one has an automatic engine start function with the ability to control temperature. Only now, in an effort to make the most versatile system, the engineers from Scher-Khan went a little further, equipping the module with protocols for enabling Pit-Stop, Turbo and standard start-up with warm-up engine start intervals (2, 4, 8 and 24 hours). But at the same time, they did not forget about the safety component, for which they naturally occupy such a high line in the final list of the best.

Advantages

• multifunctional, but not overloaded system;
• a wide range of operating temperatures – optimal performance for the climatic conditions of Russia;
• contrast control display on the key fob, ease of use;
• operating range up to 1.5 kilometers;
• proprietary communication channel protection system.

disadvantages

• not found.

Alligator C-3C

Car alarm rating: 4.5

A fairly budgetary version of the car alarm, providing users with a full layout of the available connection interfaces and even the ability to connect a GSM module. The main feature of the Alligator C-3C is the support of the connection via CAN, CAN-LIN and 2CAN to the digital bus, which makes it absolutely suitable in any model of any car brand.

A dynamic code acts as an encryptor of the communication channel of the original block with a key fob, the selection of which is impossible under the conditions of using known code grabbers. By the way, about the key fob: it has four control buttons (one of which is the engine control button) and a display for receiving notifications. And besides, there is not one in the kit: a similar model is used as a spare duplicate, but without the possibility of receiving a return signal (with three buttons without a display). Thus, behind a simple-looking device lies a very cool model that not only provides security for the car, but also makes it possible to fully control the preliminary start of the engine, and, moreover, with the ability to monitor its temperature in real time.

Advantages

• relatively inexpensive device;
• the ability to control the start of the engine with monitoring its temperature;
• two keyfobs (by analogy with the Centurion IS-10) with and without feedback reception;
• dynamic encryption of the data transmission channel;
• the ability to connect additional modules and interfaces.

disadvantages

• all CAN-interfaces and GSM-module are optional (extra charge).

Centurion IS-10

Car alarm rating: 4.4

The control of this car alarm is based on a standard key fob with three control buttons, a communication channel with the main working unit and a display for viewing notifications. The Centurion IS-10 does not provide for the presence of an application and communication with a smartphone, so the key fob remains the only and vital object of manipulation. The communication channel here is encrypted using the 3DU code system – quite reliable, but still prone to rare hacks.

Of the main advantages of the Centurion IS-10 car alarm, users highlight the implementation of the ability to automatically start the engine and a very sensitive (within reasonable limits) shock sensor, which automatically sends a signal to the key fob with feedback (because the kit also includes a standard key fob without OS). Thus, it was possible to prevent more than one case of vandalism with cars, and this is a great advantage of this device. In addition, experts note the similarity of the Centurion IS-10 to the StarLine A93 – the first is a quite high-quality replica of the second.

Advantages

• there is an engine autostart system;
• very sensitive shock sensor;
• the set includes two three-button remote controls (with and without feedback, simpler).

disadvantages

• rarely, but exposed to code grabbers.

The best alarms with GSM module

Pandora DXL 3910

Car alarm rating: 4.9

An expensive and high-quality premium-level security device, which is controlled through a special application for a smartphone (no options, since there is no regular key fob). The system has no Bluetooth – interface, therefore communication is established only by connecting via a GSM module. However, this has little effect on the efficiency of work – GSM is distinguished by its high reliability and a long operating interval.

A very important function of the Pandora DXL 3910 car alarm is the presence of an autonomous energy source – a CR 2032 battery, which ensures long and stable operation of the device without recharging. Like all self-respecting premium level alarms, this device has a CAN connector in the kit, suitable for connecting the main module to a standard digital bus. This greatly facilitates the work of the master and guarantees the possibility of installation on cars of any make and model. As a final positive fact in the 'biography' of the DXL 3910, we can note the results of independent expert tests, in which the complete deactivation of the module was performed only 1 time out of 75 attempts, which speaks for itself.

Advantages

• availability of programs for automatic start of engines and interior heating;
• CAN interface included;
• very high safety performance according to test data;
• standard battery, giving the system the ability to work autonomously.

disadvantages

• absence Bluetooth – interface for local work with signaling.

StarLine Twage B94 GSM Slave

Car alarm rating: 4.8

A premium segment security system that takes under control not only the safety of the vehicle, but also individual systems: a fuel pump, an air conditioner and light indication. Together with the central unit, a special key fob is supplied in the StarLine Twage B94 GSM Slave set, which receives notifications about various changes in the car's condition. In addition, the alarm has the ability to connect with a smartphone, as well as a keyless bypass of the immobilizer to start the engine (including by the set timer).

The theoretical communication range of the central unit and StarLine Twage B94 GSM Slave keyfob reaches 2 kilometers, after which the built-in GSM module begins to respond for notifications. At the same time, control over the safety of signal transmission is given to a two-stage protection system, which shows good results in preventing the reading of the digital code of wireless communication sources. Ultimately, the user receives a very stable and well-organized car alarm, which monitors the state of the car in the complex, and not in a separate anti-theft security parameter.

Advantages

• the ability to control various standard car systems;
• keyless bypass of the immobilizer;
• a dual communication protocol is implemented (via Bluetooth and via GSM);
• two-level protection of the communication channel from hacking.

disadvantages

• the placement of the control unit requires serious disassembly of the panel.

Pandect X-3150

Car alarm rating: 4.7

The third line of the rating goes to a product developed by the Pandect company with impressive hardware equipment and amazing ease of use. Burglary protection in the X-3150 is due to the presence of a dialog dynamic code (for communication at 868 MHz), which changes every time the central unit requests – this implementation nullifies almost all attempts of unauthorized access. It is possible to integrate the base via GSM or Bluetooth interfaces, as well as keyless access with bypassing the immobilizer. This, in turn, allows the car alarm to automatically start the engine with the regulation of the preheaters.

A special control key fob is supplied with the Pandect X-3150 car alarm, which can be replaced with a smartphone with the application installed. But, perhaps, one of the main advantages of the alarm is that it comes with a multi-system CAN interface for integrating the central unit with the standard digital bus of the car. This allows you to avoid additional expenses and makes the device one of the most complete in its segment.

Advantages

• maximum set of functions for comprehensive monitoring of the state of the car;
• the ability to automatically start the engine and monitor sensors, temperature, battery charge, etc.;
• availability of a universal CAN interface;
• the ability to connect with a smartphone via Bluetooth and GSM.

disadvantages

• not found.

The best telematic car alarms

StarLine M96 L

Car alarm rating: 4.9

The signaling system, which is quite controversial in its conservatism, the main disadvantage of which was the absence of a keyless bypass of the immobilizer. Instead, the designers of StarLine M96 L relied on increasing the reliability of the device in emergency conditions, as well as its versatility. Unlike other representatives of the category, this car alarm has its own lithium-ion battery, which maintains the operability of the central control unit even if the on-board power supply is disconnected (battery is removed).

In addition, a very serious advantage of StarLine M96 L car alarms is the ability to establish a connection with a smartphone via Bluetooth or GSM-connection, which is very convenient for business trips abroad or traveling. Let's not forget to mention the ability of the system to automatically notify the car owner about failures in the fuel supply system: the central unit is connected to the vehicle's on-board computer and retrieves information about the malfunction by a simple request. All this makes the M96 a special device that will definitely become a guarantor of safety for your car.

Advantages

• relatively high reliability of the system (for complete decontamination it requires a serious analysis of the main panel);
• communication between the alarm and a smartphone can be established via two channels: Bluetooth and GSM;
• built-in autonomous power supply unit;
• the ability to receive information about a malfunction of the injection system via SMS notifications.

disadvantages

• the function of unlocking the immobilizer without a key is not implemented.

Pandect X-1900 BT

Car alarm rating: 4.8

The second line of the rating goes to the Pandect X-1900 BT not by chance – this device has a sufficient number of 'chips' in its assets. The new development has demonstrated excellent possibilities in terms of authorizing the driver to access the car – this can be done over the network Bluetooth through tags, a smartphone (a special application is required) or a Pandora smart watch. GPS / GLONASS systems are also integrated here, as well as the possibility of keyless bypass of the immobilizer. There is a function of adjusting the range of the Hands-Free system, which allows you to automatically unlock the car when the owner approaches a certain distance.

Of course, it is foolish to believe that the Pandect X-1900 BT car alarm has no flaws. As users and installation experts note, this alarm, although it works with satellite communication antennas, does it extremely reluctantly and capriciously. It's all about the location of the central unit under the panel: despite the compactness and the possibility of fixing, in fact, anywhere, a very important stage of the installation will be to find the optimal point without any interference. Ultimately, the car alarm from Pandect, although it represents the premium segment, has a number of point problems that prevent you from fully evaluating the advantages (of which there are many).

Advantages

• small-sized central unit, convenient for placement in a dense layout;
• allows you to bypass the immobilizer without using keys;
• Hands-Free system, which adjusts the sensors triggering to approach the owner of the car;
• implemented authorization through the system Bluetooth from a smart watch or smartphone;
• GPS / GLONASS support.

disadvantages

• the impossibility of connecting with an external antenna for receiving a GPS signal – hence the problems with the placement of the central unit.

Ghost-840

Car alarm rating: 4.7

The leading car alarm among the entire range of 'Ghosts', which supports control both with a key (standard method) and through a special mobile application. It is noteworthy that in all these cases, to access the passenger compartment, either RFID tags with an encrypted code (remote opening method) or a pin code (using the on-board system buttons) must be used.

Communication with the central unit in the case of the 'Phantom-840' is established by laying a 12-volt wire directly to the pLine-221 microrelay, which (due to its compact size) can be placed under the control panel almost anywhere. This method of connection is several times safer than a remote one – if the radio wave communication can be intercepted, then the wired method of data transmission requires connecting the device to the control unit, which is very long, costly and unsafe for the potential burglar himself. However, even if you succeed in removing the alarm itself, the built-in accelerometer of the control unit will perform the function of blocking the engine start, which will nullify attempts to steal the car on its own.

Advantages

• works bypassing the immobilizer (from the key);
• provides protection against starting the engine in case of unauthorized access with the removal of the signaling device;
• reliable wired connection of the micro-relay and the central unit, immune to radio wave hacking.

disadvantages

• for systems without support for autorun via CAN-bus, purchase of an additional power module ESM-250 is required.
