Radar complex KKDDAS STRELKA 01 ST- the most perfect to date, of the traffic police used. This complex was developed for military aviation, where it was used for covert and high-speed interception of military targets, and was inaccessible to detection by any military radar detector. To date, complexes "Arrow ST and M" It is also used by traffic police and traffic police to detect violators at fairly decent distances.
So what are the features of the work of Strelka?
Firstly, this is the range, Strelka has on board a unique video recording camera capable of detecting a violation speed limit at a distance of up to 1 kilometer. The driver cannot see the "STRELKA" at such a distance (without the use of radar detectors capable of detecting it), and this is sad news.
Secondly, this radar complex monitors not just one violating car, but scans the entire traffic flow, analyzing all lanes of one direction at a distance of up to a kilometer.
Thirdly, this automated traffic police radar complex can be used both by the stationary "Strelka ST" and the mobile version - "Strelka M"
The principle of operation of the Strelka ST complex:
1. pulse radar emits short pulses that propagate along the entire roadbed.
2. All signals reflected by vehicles within a radius of up to 1000 m enter the computing unit, where data on the speed and range of the vehicle are generated.
3. Immediately, the object recognition program begins to highlight moving cars and calculate their coordinates, build a trajectory of movement and determine their approximate speed.
4. The data from the radar and analyzer are transferred to the cross-correlation program, which combines these indicators, after which the vehicles exceeding the speed are determined, and when they approach a distance of 50 m, they are photographed.
Wherein radar complex "Strelka ST" can analyze the situation in all weather conditions (it is able to operate at temperatures from -40 to +60 degrees) and also withstand 98% humidity. The complex is also manufactured in an anti-vandal housing and, accordingly, cannot be mechanical damage(from particularly nervous drivers :-)). Traffic police and traffic police consider this video radar one of the most effective, which is close to the truth - the Strelka radar system has excellent performance.
The disadvantage of the complex is a considerable price, along with attachments, mast and electricity supply exceeding the figure of one and a half million rubles. It is the economic factor that is currently holding back the distribution of complexes everywhere, but gradually there will be much more of them, the price factor goes into second place - after all, the income from Strelka (here they are - letters of "happiness") make it possible to install them regardless of the high cost.
Advantages - Radar systems "Strelka ST and M"completely eliminates errors in fixing the speed of cars and is considered very effective from an economic point of view. Police officers have the ability to accurately record speed violations on the roads and provide the driver with reliable evidence of these violations. These systems also guard the rights of the drivers themselves, because thanks to they can be sure that traffic police or traffic police officers do not charge them with false accusations and do not force them to pay fines for imperfect actions.
Nowadays, every self-respecting manufacturer radar detectors released a series of products - which are excellent (or close to it) in detecting Strelka signals - learn more and buy these radar detectors you can on the site
"Letters of happiness" (or, in clerical terms, protocols on administrative offenses received by mail) make many people miss the good old inspectors with hand-held radars. You can’t complain to a soulless car about a hard day, you can’t lie that your wife is giving birth, you can’t offer a “fine on the spot.” She can't be fooled or outwitted. Or is it still possible?
Alexander Shevchenko
In the memory of motorists with an experience of five to ten years or more, the image of a law enforcement officer aiming at a car from a massive “pistol” is forever imprinted. This is what the main purse hunter of all speed lovers used to look like. The principle of operation of both the old hand-held radar and modern stationary and mobile ones is based on the Doppler effect. The device continuously sends electromagnetic waves towards approaching vehicles. When waves are reflected, their frequency changes, which is fixed by the receiver. Similar principles are embedded in laser speed measurement systems.
The main drawback of a simple radar was the impossibility of proving which particular vehicle the measurement result refers to. This problem opened up scope for abuse by inspectors, but also allowed the violator to avoid liability.
Therefore, hand-held radars were soon equipped with cameras that take a picture at the moment of measuring the speed. This step significantly strengthened the position of the inspector in controversial situations, but did not finally solve the problem. Controversial situations arose when two cars entered the frame at the same time. Not only that, being a ahead offender racer, a respectable driver had a good chance of getting into the frame instead of him.
The human factor, in particular, the need to "aim" at each potential violator, analyze the readings of the device and honestly write out protocols, is the main drawback of hand tools. It was possible to exclude it only thanks to the development of image recognition systems on video images.
The video camera of the AvtoUragan complex can be installed at an angle of up to 20° to the direction of traffic, and the maximum vertical installation angle reaches 30°. But the most effective complex operates in the presence of several cameras. An overview of the intersection from different angles eliminates controversial situations when the intruder tries to hide behind a neighboring car or reading the number plate is difficult. Additional infrared illuminators help the cameras "see" at night and in difficult weather conditions. In the photo: wide-angle cameras continuously read the license plates of all cars that enter the field of view. The number of simultaneously recognized license plates is not limited.
Many-eyed monster
The history of domestic image recognition began in the 1960s, but the first working video camera on the roads of Russia was installed only in 1999. There are a lot of reasons for such a long development, despite the fact that the numbers of cars are of the same type. Fastening on uneven bumpers, poor weather, “mesh” and “film” favorite by car owners, banal scratches and, finally, deliberate damage to state signs - all this clearly does not make life easier for algorithm developers. Nevertheless, modern road equipment correctly recognizes 97% of passing cars in daylight hours days and 92% in the dark.
Stationary "many-eyed monsters", now familiar to every motorist, also use radar to determine the speed of the car. An example is the Strelka-ST video recording of violations, one of the most common and formidable law enforcement officers on the road.
Long-focus cameras record violations of the rules in "their" lanes from afar. To avoid errors associated with rebuilding, the computer not only takes a snapshot of the vehicle, but also builds the trajectory of its movement.
The Strelka's rectangular case, closed with an opaque plastic cover, hides the radar. This is not the same radar that inspectors used in the 1990s. The formidable military design uses a frequency of 24.15 GHz with a pulse duration of only 30 nanoseconds. Only the most advanced radar detectors can pick up such a signal, but they are also practically powerless against Strelka. Range best radar detectors does not exceed 1 km. It is at this distance that Strelka begins measuring speed and taking photographs. The second, "many-eyed" housing contains a video camera and an infrared illuminator, which helps to shoot at night and in adverse weather conditions.
First automatic systems video recording of violations photographed only those vehicles that were moving in excess of the permitted speed. In order for the measured speed to exactly match the vehicle in the photo, it was necessary to limit the coverage area of the complex to a small section of one lane. Improving recognition algorithms, increasing the computing power of servers and bandwidth data transmission channels made it possible to circumvent this limitation.
The urban network of video cameras is useful not only for monitoring compliance with traffic rules. With its help, you can track the movements of offenders, search for stolen cars. To do this, it is enough to put the car number in the "black list", and each of its appearance in the field of view of the cameras will be accompanied by a message to the operator. With a sufficiently large number of cameras on the roads, the phrase "the attackers fled in an unknown direction" loses its meaning. All radar systems have approximately the same set of components, and this is clearly visible to the naked eye. In Strelka-ST, the radar and video camera with an infrared searchlight are located in different buildings.
Radar and camera "Strelka-ST" control the speed of vehicles passing and opposite directions on four lanes simultaneously. At a distance of up to 1000 m, the pattern recognition program generates pairs of "TS-velocity", approximately calculates the speed of the vehicle, and builds the trajectories of their movement. These data are compared with radar readings. When an intruder is detected, his car is re-photographed close-up at a distance of approximately 50 m from the camera for optimal performance of the number recognition system.
Strelka-ST, as well as its counterparts KRIS-S, CORDON, Arena and many others, have an advanced pattern recognition system that allows you to detect and record not only speed violations, but also running a red light, traffic lane for public transport, failing to give priority to pedestrians and even driving with headlights off or unfastened seat belts security.
And yet, the need to compare the radar readings with the video recording, as well as to photograph the car several times at fundamentally different distances, is fraught with a small probability of an error in comparing the speed and registration plate of the car. In radar systems that have already become traditional, the image recognition system and the radar actually duplicate each other. This duplication often contributes to accuracy, but in some cases becomes a source of ambiguity.
Modern radar systems are produced both in stationary and mobile versions. Mobile "Arena", mounted on a massive tripod, is transported in the trunk of a passenger car and unfolds in ten minutes. Via a wireless channel, the complex constantly keeps in touch with the computer in the inspector's car, which can immediately stop the intruder and draw up a protocol. The second option is to transfer the daily records of the complex to a citywide database on a flash drive for automatic distribution of "letters of happiness".
Smart Cyclops
Specialists from the Moscow-based company Recognition Technologies told Popular Mechanics how, with the help of advanced algorithms and sufficient computing power, a radar can be excluded from the system, thereby only increasing its accuracy and reliability.
The AvtoUragan violation detection complex recognizes the license plates of all cars caught in the frame of a wide-angle video camera with amazing accuracy. With uniform contamination, the minimum allowable contrast of the license plate image reaches 10%: the system easily recognizes the license plate of an SUV that has just returned from a truck trial competition. The number of simultaneously recognized license plates is not limited.
The speed of the car is determined based on the geometric properties of the area that the camera observes. Knowing the dimensions of the roadway and the travel time of the car (determined by the number of frames in which the car number is present), it is easy to calculate the speed. Moreover, this can be done quite accurately: the determination error is only 2 km / h, and the maximum recorded speed reaches 255 km / h.
Analyzing the image of the car, it is also possible to identify the passage of a red light (including railway crossing), driving into oncoming traffic, stopping behind the stop line, and even the fact that the driver gave way to a pedestrian. Full list recorded violations is constantly growing.
Outwardly, the AvtoUragan complex is just an inconspicuous video camera - the same as those used in security systems. The camera can be mounted discreetly - on high altitude or at an angle to the road. Max Angle installation reaches 30° vertically and 20° horizontally. Of course, the AvtoHurricane is completely invisible to radar detectors.
If the mountain does not go to Mohammed
Brave speed-breakers find the cameras themselves, and there are more and more of them. And what about the always hiding drivers who despise parking rules on quiet city streets? The system of video recording of violations will come to them by car.
Who or what sends us fines? Information from video recording complexes is sent to a single server. Separate servers are allocated for high-traffic intersections, 6-12 camera systems on large freeways, and other busy areas. The server remotely resembles a personal computer. It does not have a monitor and peripherals, but it is located in an anti-vandal outdoor cabinet and can work 24 hours a day. On the server, a set of frames from video cameras is converted into speeds and license plates (not only violations are recorded, but also the passage of cars within the rules). This information is sent to single base data of the city where the identity of the violator is established and the decision is formed. Video recordings of violations are partially viewed to control the operation of the equipment. Formed resolutions are sent to vehicle owners by mail.
One of these complexes, called APK ParkRight, is also produced by Recognition Technologies LLC. Two video cameras (recognizing and survey), an IR illuminator for working in dark time day, touch screen, as well as built-in GLONASS / GPS receivers, Wi-Fi module and GSM modem - all this is placed in a small monoblock, which is attached to windshield patrol car. As in the case of stationary complexes, the registration of offenses occurs completely automatically, and the operator only monitors the process and makes changes. Moreover, due to their autonomy, such complexes can be found in conventional buses, ambulances and rescue vehicles.
But what to do with cars parked in "hard-to-reach" places - where there is no access by bus or patrol car? They can be reached on foot. This year, the inspectors of the traffic police entered service with the ParkNet APK, made in the form of a tablet, capable of controlling paid parking, as well as fix violations of the rules of stopping and parking cars. Photo fixation of the fact of violation takes the inspector about one minute, and work via wireless communication lines allows you to immediately send a request for the evacuation of the car and check the state register sign for presence in the wanted database.
Perhaps in a few years, everyone will be able to record a photo or video of an offense on a smartphone, registrar or google-glass and send it to the traffic police data center. A corresponding application is already being tested in Recognition Technologies. Specialists pay Special attention photo compression algorithm. For the speedy accomplishment of justice, it does not matter how accurately the color of the car and the details of the landscape are conveyed. The clarity of the number and the size of the file come to the fore, which should be easily sent to the traffic police server even from areas with uncertain cellular signal reception.
Perhaps in the future, traffic control on the roads will move inside the car and become active: the cars themselves will prevent traffic violations. I would like to believe that domestic systems in this market will take a confident position. We have someone to work out algorithms on, because we have more than enough violators.
A lot of letters come to my blog to tell about the "cunning" radar that is installed on Russian roads, called "STRELKA". Not all radar detectors catch it, especially the budget category, and therefore there is a high probability of getting caught! Of course - do not violate, and then you will not pay any fines. But it happens that when you arrived in another city, you didn’t see the “20” sign and violated it, there was such a system nearby that filmed everything. And your radar detector was treacherously silent. In general, today I decided to tell you what this device is and how to deal with it ...
To begin with, as usual, the definition
Radar complex KKDDAS "STRELKA" 01 ST - This is a stationary automated complex in the service of the traffic police, which fixes traffic offenses (mainly speeding). It should be noted that this device measures the speed of not one car, but several at once (which fell into the coverage area). The distance of this system is impressive, as the manufacturers themselves say, precise definition rooms can be at a distance of 350 meters, and the complex itself operates up to 500 meters.
The history of the appearance of "STRELKA" goes back to aviation - it was there that the first models appeared, initially they captured the speed of flying military aircraft. The task was set as follows - so that this complex could not detect more than one identification electronic sensor enemy. The complex coped with its tasks by 100%.
Much later, versions specifically for the traffic police began to appear, if you want, they were simplified and sharpened specifically for road conditions. The production is carried out by the Nizhny Novgorod company "Systems Advanced Technology».
After testing on the roads, "STRELKA" showed its effectiveness, many radar detectors were simply silent and did not catch it. That's why road police acquires such installations in droves, only in 2014, 2000 units were installed on the roads of Russia.
Varieties of systems
There are currently two options:
Stationary- it can be attributed to "STRELKA ST"
Mounted on large racks above the road (at a height of 5 - 7 meters). If the road is large (from 4 lanes), then there can be up to 4 such devices on the rack.
Mobile- this is the so-called "ARROW M"
The traffic police cars are completed, as a rule, these are GAZelles or other minibuses. A camera and a radar itself are installed on the mast that rises on the roof of the car. The system is fully automated, the mast moves out and turns with the help of electric motors. Here is a small photo for understanding. Such a complex can move anywhere, unlike the first option. Max Height about 4.5 meters.
How it works, what it consists of
You are probably wondering what is inside it. It's simple - this is a conventional radar sensor, built according to the classical scheme with digital accumulation and pulse processing.
Operates at frequencies of 24.15 GHz, the pulse is repeated every 25 microseconds. The system accumulates for each element of the range on the road certain information obtained from the transformation of the spectral analysis of the target. Unlike other radars, this system receives data not only from the Doppler velocity, but from all reflected areas of the target. The target position data is then generated and transmitted to the main computer (processing speed is now about 80 ms), which is perfectly synchronized with the video signal (which has a frame rate of 12 per second).
Why don't radar detectors catch Strelka?
First, let's define the fixing process. Approximately at a distance of 200 - 300 meters, the radar part captures the speed limit, after the vehicle approaches 150 - 200 meters, the photo part turns on, which removes the offender's license plates ( automatic detection rows and stripes).
But the radar part does not work like conventional systems. A short pulse (low frequency) is sent here, and not an electromagnetic signal (as in devices - a class lower). Most cheap and average radar detectors simply cannot catch such impulses, and therefore are silent! This is the main reason.
Of course, there are more expensive options, they are already effectively fighting such radars.
How to protect yourself?
“Why is there no protection at all?” - you ask. Guys calmly, of course there is. Personally, I conditionally divide them into three main types:
1) These are license plate stickers. To be honest, use the guys at your own peril and risk, of course they don’t always “roll”, but there are a lot of tales on the Internet - that they work! The principle is simple, you stick a couple of letters or numbers - the camera of this complex is infrared and when it removes such stickers, the numbers under them seem to disappear. Here is a small example. I’ll make a reservation right away - they are fined for this and license plates are removed, so think for yourself!
2) Buy a radar detector that catches the arrow, now there are many models that catch such short pulses, although their cost is high price category. A small video of work.
3) Remember the location and add it to the maps of the navigator. The thing is that "STRELKA ST" (stationary) is almost always rigidly mounted on a frame above the road and it is quite easy to remember such an arrangement. Moreover, in our city you can count them on the fingers, and if you often travel to neighboring cities, the location can also be easily remembered. Mobile installations are very rare on the roads, although there are many more in the metropolitan areas.
In conclusion, I would like to say that the traffic police does not stand still, but develops in step with the times, so the guys have two options - either drive according to the rules without violating (which is not easy enough in the modern stream), or defend themselves from all sorts of "ARROWS". ”, “BUTONS”, “PARKONOV”, etc. systems by buying expensive radar detectors (you pay once and 80 - 90% seems to be protected).
Of course, not everyone is ready and eager to install a radar detector in their cabin, operating at prohibited frequencies, actively suppressing the signals of stationary and mobile traffic police speed control equipment. This is quite understandable, because if this fact is discovered, the device will naturally be confiscated, and its owner will be fined several dozen minimum wages. A reasonable, and most importantly, legal alternative to such extremes is a new generation of radar detectors, which have all the technical capabilities for early detection of almost all road monitoring systems common in the Russian Federation.
Among the most advanced monitoring systems traffic situation can be attributed to the stationary system "STRELKA-ST" and its mobile modification "STRELKA-M", the early detection of which, until relatively recently, represented for drivers serious problem. About how effectively this problem is being solved today, you can learn from our article.
"Letters of happiness" - protocols with a notification of an administrative offense received by mail - this is what makes drivers periodically yearn for the good old days, when inspectors with hand-held radars paraded along the roads. The main drawback of the simplest radar, and the source of constant controversy on the road, was the difficulty of proving that a particular vehicle was speeding. And the search for a more efficient solution continued.
The simplest hand-held radars, which open up the widest opportunities for abuse to inspectors, and violators to avoid responsibility, were soon replaced by hand-held radars, equipped with cameras that allow taking a photograph at the time of measuring the speed. However, this did not completely solve the problem of unambiguous identification of the offending vehicle, since several cars periodically fell into the frame at the same time. At that time, respectable drivers, who got into the frame at the moment of overtaking their car by an intruder, felt this problem especially acutely.
The human factor was completely eliminated by automatic systems for video recording and pattern recognition on a video image. And today in the field of our attention is one of these systems - Strelka and its mobile and stationary modifications.
For those who have not yet had time to personally get acquainted with the capabilities of the Strelka complex (“ST” - stationary and “M” - mobile options) and have not yet acquired a combat-ready radar detector, we will introduce key features And technical advantages this system.
The KKDDAS ’STRELKA ST’ radar complex is a product of the Russian company Advanced Technology Systems, which has been actively lobbied by the Moscow traffic police since 2013. The complex was developed in stationary ("Strelka-ST") and mobile ("Strelka-M") variants.
mobile version“Arrows” are most often installed on converted vehicles with a reinforced power frame on the roof and a special boom lifting mechanism and a video radar sensor. The available boom lifting height is 4.5 m. The capabilities of the slewing device on the boom allow turning in the elevation and azimuth planes in the range of 20 degrees. Rotation, control of the position of the sensor and lifting of the boom is carried out by means of an electric motor controlled by the inspector from the computer monitor.
The system is powered by battery, which can be charged in two ways: from a standard 220V network and from a gas generator in the back of the car. The use of the mobile version of the Strelka-M system obliges the inspector to continuously monitor the situation and make prompt decisions.
Omnipresent Strelka-ST
Stationary development uses a frequency of 24.15 GHz and pulses with a duration of 30 (!) ns. Such short impulse signals at a certain stage were able to catch the most advanced radar detectors. The problem was further aggravated by the fact that the threshold value for the detection range of an offense (including night time, bad weather conditions and temperature fluctuations from -40 to + 60 C) in the Strelka ST system is 1 km, which came close to the effective range of many early models radar detectors, nullifying the possibility of early warning.Due to the increase in the computing power of servers, the bandwidth of data transmission channels and the improvement of recognition algorithms for “tadpoles” from “S.P.T.” managed to expand the recognition zone from a limited area of one lane in the first video recording systems to 4 lanes in the Strelka system.
At the same time, the formation of the information pair “TS-velocity” by the pattern recognition program is carried out already 1 km before Strelka. At the same time, a preliminary calculation of the speed and trajectory of movement is carried out. The calculation data are compared with the radar readings by the cross-correlation program. When a violation is fixed, a second picture of the car is made already at a distance of 50 m from the camera.
Structurally, the complex of the stationary version of the Strelka-ST system consists of two parts. The first is the actual radar installation, the principle of operation of which is borrowed from military aviation systems. The second part of the kit is a wide-angle camera.
The main difference between the domestic "Strelka" from most Russian (competitor - new development“Krechet” is a tracking 2D photoradar with the ability to control the location and speed of the vehicle simultaneously on 4 lanes of multidirectional traffic) and foreign analogues- the ability to control 4 lanes at the same time, regardless of which direction the vehicle is moving. At the same time, the zone of control of many existing systems is still limited to a section up to 15 m wide, which affects the completeness of the recorded information - full or partial “cutting off” of the number, etc. And since it is unambiguous to identify the car and its owner in this case problematic, then the claims from the traffic police can be easily challenged in court.
Fixation of the offense by Strelka is carried out in automatic mode. The photographic image of a car that has exceeded the speed limit is supplemented with data from the traffic police database, requested by the system after fixing the fact of exceeding the speed limit. Thus, in the hands of the inspector is a fully completed protocol form with the amount of the fine, which remains only to send by mail.
The range of the radar makes it possible to fix a violation at a time when the driver, who does not have adequate technical protection means, is unaware of the existence of equipment placed above the road. Moreover, even if the speed is reduced to the permissible level when approaching the system, the existing fact of its excess at a point at a distance of up to 1000 m from Strelka will in any case be recorded. When approaching the camera, the image of the offending vehicle will be automatically cut out and processed. In addition to the fact of speeding, Strelka will record a violation of the marking requirements and passing a prohibiting traffic light.
Advantages of the Strelka ST system
- Automatic formation of a freeze-frame of the car with a clear fixation of the state number;
- Automatic signal processing from the entire width of the road (up to 4 lanes);
- Automatic generation of a report on the key parameters of the movement of the intruder's object (speed, range, etc.);
- Automatic forwarding of an ordered data stream to the traffic police computer;
- Automatic generation of a command (at a distance of about 50 m from the object) to detect and recognize the vehicle number.
Searching of decisions
The appearance of "Arrows" on Russian roads nullified the capabilities of the vast majority of radar detectors, which reacted to it in much the same way as to a tin can on the side of the road. Two years of painstaking work - exactly that much was needed for the developers of radar detector systems in order to create a chip that allows you to accurately fix Strelka at a distance of up to 1 - 2 km to the point of "contact". The first models equipped with a revolutionary board were released only in 2012 and still show excellent detection results.Historically, these are, first of all, Street Storm products - the STR 9510 radar detector model, equipped with an integrated GPS module. A high level of information content during the early detection of Strelka was achieved not only thanks to the radar part with the then innovative ST MicroElectronics chip with High Sensitivity Platform (HSP) technology, but also thanks to the built-in and complete pre-installed database of existing Strelka ST radar tracking systems ”, including: azimuth, coordinates, radar type, speed limit in a particular area. At the same time, one of the most important conditions for the reliability of the readings of the device - the relevance of the database turned out to be easily feasible, since the latest updates are always available on the official website.
Built-in GPS-detector module - what is it?
simple and effective method detection of Strelka speed control systems, etc. is based on the use of a GPS signal receiver and POI points provided by the manufacturer of the radar detector model or third-party database providers.Advantages of the method:
- This technologically simple solution allows you to determine the probable position of Strelka ST not only with a radar detector, but also with a smartphone or car navigator.
- The use of such an early detection method is applicable not only to equipment for measuring vehicle speed, but also to detect and enter into the database own data on other objects that pose a certain danger to the driver.
- The need to constantly maintain the database up to date. The inability to determine whether the camera is working in the displayed POI or not.
- Dependence of the quality and stability of the GPS signal on the weather factor and movement conditions (tunnel, etc.). Such "blind zones" open a loophole for the loss of fundamentally important information.
Both models demonstrate stable early detection of Strelka ST/M Robot MultiRadar signals and other road monitoring systems, have a built-in GPS receiver, and work with a 360-degree coverage area. Support is provided for notification of the action of the signals of the traffic police monitoring system in several modes at once - visual (strobe LEDs, textual information, sound and voice duplication in several languages).
Effective protection against false positives (opening automatic doors of stores, gas stations, etc.) is provided unique system signal filtering.
Comparative testing of the Whistler WH-559ST+ (model of 2013) and the Escort Passport 8500 premium segment models showed excellent tracking results for both models, with the WH-559ST detecting an object at a distance of 1100m, while the Escort Passport 8500 was only 100m earlier. 
Testing the capabilities of the Whistler PRO-99ST+ GPS module with a fresh database
Budget segment
A popular and inexpensive “state employee” (up to 10,000) that perfectly solves a set of tasks is the PlayMe OUICK radar detector (Korea) with a GPS receiver and an LCD screen, a function voice alert and protection against false positives. It has impressive functionality, typical for a number of models of the middle price segment, and at the same time compares favorably with them in price.
PlayMe OUICK with GPS receiver
Absolute leader
IN model range in the premium segment, the leader's place firmly holds the radar detector on a fundamentally new platform Escort Passport MAX Intl (Canada), having maximum technical indicators. Equipped with two progressive DSP processors that provide independent control of processing algorithms and a qualitatively new level of performance, the function of AUTO screen adjustment, display brightness adjustment, the ability to record coordinates with potentially dangerous areas way.Escort Passport MAX Intl (Canada) is the only model that allows you to selectively turn off any of the ranges (including) the laser, X-band, K-band (transition to K1, K2, K3), as well as fine-tune frequencies in the K-band, which is essential increases the immunity of the device.
So, for example, by turning off the K3 band, you deactivate reception at unclaimed frequencies above 24 GHz. By turning off the “Laser”, you, accordingly, deactivate the detection range of laser monitoring systems, which are quite rare on Russian roads today, etc.
To detect Strelka and MULTIRADAR, you can use a special range that will allow you to get the most complete information about these speed measurement systems (including the type of system, signal strength, frequency of the detected signal, type of radar (M - mobile or C - stationary)).
The function of simultaneous detection of up to 3 signal sources in each of the scanning ranges is very convenient.
According to the test results, the Strelka ST system was detected by the Passport MAX radar unit at a distance of 1950 m. maximum level signal (12 divisions). Confident detection of ROBOT MULTIRADAR, KRIS-P, AVTODORIYA, ODYSSEY, AVTOURAGAN, Strelka-Video, Keon, Vocord, Gasto systems (fixed by the GPS module), stop-line cameras of traffic lights, dedicated lane cameras, etc.
The capabilities of the model make it possible to confidently detect most systems at a distance of 1.5–2 km. The exception is the MULTIRADAR ROBOT, whose signals Passport MAX fixes “in the face” from about 700 m, “in the back” - continues to fix at a distance of up to 500 meters.
The main board and the GPS receiver board are separated, which is practically impossible for the radar detectors of Asian companies. At the same time, the innovative GPS board, made on the innovative SirF Star IV platform, is equipped with an independent cooling system that prevents the board from affecting the operation of the main radar board and, as a result, the accuracy and stability of the device readings. Interesting feature models: when alerting the coordinates of the control object, the detector warns the driver the earlier, the higher the speed of the car. 
All of the above models are adapted to Russian conditions driving and Russified, have open access to updated databases and software on the developer's websites, are supplied under warranty.
As you can see, there are more than enough ways to solve the problem of early detection of Strelka ST/M systems, as well as other common road monitoring systems. Moreover, effective models are presented in each of the price segments. Naturally, additional options and enhanced capabilities will require larger investments. But, in comparison with the potential costs of probable traffic police fines, investments in one's own comfort and safety seem more than justified and uplifting.

The radar, known as Strelka ST, operates on a carrier frequency of 24.15 GHz. The "picture" of a car's license plate is made up of 6-8 frames taken sequentially. Due to these circumstances, no need to rely on equipment inaccuracy or luck, because the degree of recognition is on the highest level. But try to cheat infernal machine Can. But how?
At what distance does the Strelka-ST radar catch? How is speed determined?
The radar starts to "guide" the car from about 400 meters, in conditions of good visibility and clear optics, but the numbers may vary. Special fans keep the lenses clean. At first, the car does not lend itself to any identification, and only license plate is photographed at a distance of 40 meters. The photo will include maximum speed for the period of observation of the car by Strelka ST (not the speed that was at the time of shooting the numbers).
At what distance does the radar detector catch Strelka ST?
Most "anti-shooter" radars can pick up the signal of the Strelka ST at a distance of 600 meters or more. But you should not rely solely on the anti-radar, because in dense traffic you will not be able to slow down sharply. You need to carefully follow the road and look for not at all compact photofixation terminals (it’s not hard to recognize them). Long work, temperature changes, different weather conditions can significantly reduce the intensity of radiation. Because of this, the anti-radar will react within the range of the Strelka, which reduces its effectiveness to nothing.
What to do with false positives?
The anti-shooter radar sometimes works falsely, because it can receive radiation from radars that you have already passed and Strelok located on the opposite lane. Often a false alarm can be seen on the ascent inside Moscow Ring Road, especially in front of the overpass through Yaroslavka.
Is it possible to deceive Strelka ST at night?
At night, Philips IR illuminators can illuminate license plates at a distance of up to 150 meters. Therefore, it makes no sense to hope to slip through this high-precision device at night.

Does changing lanes help?
If you find the arrow late, but you are still within the license plate recognition distance, it is better to change lanes to the next lane or make multiple lane changes. When performing this maneuver, there is a small chance that the radar will lose sight of your car. Does it help?
Examples of license plate recognition by Strelka ST radar during rebuilding.
But in any case, maneuvers will not save you from fixing the number. The Arrow's camera is positioned in such a way that it can read the license plate from any angle.
Hiding behind a truck or bus
You can stand in a row behind the truck - very good way"get lost". Helps? No!
We stop in front of Strelka ST
You can try to erase yourself from the CT Arrow's memory by stopping for a few minutes before taking a photo. In this case, the traffic flow should be of medium intensity. If the road is empty, then you will have to stop for a longer period of time. It is necessary that at least 10 cars pass during this time.
Pull over or just drive around
Undoubtedly, the variant of the exit to the side of the road is possible, leaving the recognition zone of the Strelka ST radar. Another way is to cover the license plate with something.
If the car in front of you is moving at high speed and it is within the range of the CT Arrow, do not get too close to it, because the device can “attribute” its speed to you. The developer assures that this is impossible, but the probability still remains.
Non-working Arrows and dummies
About a quarter of the Shooters in Moscow do not work. They have broken down and are waiting for maintenance work: they require replacement of the fan, IR illuminators, optical lenses, etc. And some just don't connect. Also on the roads you can meet a large number of dummies, especially on the outskirts and the Moscow Ring Road. IN within the Third Ring Road the serviceability of the Strelok is monitored quite well, but sometimes some are turned off. This is done when the flow of fines does not have time to be processed in the centers.
If there is a temporary speed limit on the section, then the Arrows do not reconfigure. The only exception are Men at work on the Moscow Ring Road, but sometimes the radars may also not reconfigure.
If there is no radar unit on Strelka, which is usually located on the right, then the device only controls the exit to road lane on which public transport travels. Such a radar does not fix the speed, so you don’t have to worry. The departure of the car is determined automatically and a file with a photo is immediately generated, sometimes the fact of the departure may not be recorded. Even in such cases, the letter will come to your address. You can’t prove anything, it’s better not to drive near the public transport lane. It is possible not to receive a letter of violation only if Strelka is not working or the optics are very dirty.
Are there Arrows fixing rear numbers?
Motorists say that sometimes CT shooters are placed so that they record the rear license plates and the speed of a departing vehicle. This is probably a way to pacify motorcyclists who simply do not have a front sign. However, we do not know anything about this method of installation.
What other offenses is Strelka ST used to fix?
Here's what Arrow catches:
- Over speed
- Crossing the center line of the marking
- Driving through a prohibitory traffic light sign
- Departure to the lane for public transport
- Drive to the curb or sidewalk
How much does the Strelka ST radar complex cost?
The base cost of the Strelka ST radar is approximately 3,800,000 rubles. Add to this the cost of installation, laying communications and communications, as well as periodic maintenance, incl. replacement optics. Thus, for each complex from the treasury, you will have to pay not less than 4.000.000 rubles.
