At what distance does the camera record a violation?

Secrets of traffic cameras: at what distance to brake to avoid a fine

Our readers often ask the question about the distance at which cameras recording traffic violations begin to drive a car, and about the maximum speed that all-seeing eyes can detect. We answer.

APK "AvtoUragan-VSM2" from the company "Recognition Technologies" is a multifunctional photo and video recording system capable of detecting 17 different violations of traffic rules. Among them are: driving through an intersection when there is a prohibiting traffic light, going beyond the stop line at an intersection when the traffic light is prohibiting, driving through a railway crossing when the traffic light is prohibiting, under a prohibiting sign, along tram tracks in the opposite direction, along bicycle paths, pedestrian paths and sidewalks, on the side of the oncoming lane. But the first point is to record speeding.

To overtake the AutoHurricane you will have to be very fast - according to the official specifications, the system catches everything that moves up to 255 km/h while simultaneously processing 4 lanes of traffic. Information about the distance at which the complex begins to record driving sins is not provided.

The new generation photo and video recording complex “Avtodoriya” from the company of the same name is an extremely unpleasant contraption for violators and has an excellent “appetite”. It can punish for speeding, driving in the public transport lane or on the side of the road, violations of parking and stopping rules, driving through a prohibitory traffic light, driving beyond the stop line and other sins.

In addition, Avtodoriya is trained to measure the average speed over a section from 250 meters to 10 kilometers, although there is actually no limit value. The company told us that the all-seeing eye begins to guide a car moving at speeds of up to 300 km/h at a distance of about 100 meters. To outwit Avtodoriya you will have to buy a Koenigsegg or Bugatti.

But * “Odyssey” from TCBODD LLC (“Technical Center for Road Safety”) remained a mystery: with a radar speed meter, it catches vehicles up to 255 km/h, but the manufacturer refused to name its range of operation for obvious reasons.

In total, “Odysseus” helps to “rebuke” those who violate violations for 12 sins. For example, driving through a prohibitory traffic light, crossing a railway track outside a railway crossing, entering a railway crossing with a closed or closing barrier or with a prohibiting traffic light, entering the lane of oncoming traffic and tram tracks in the opposite direction, failure to comply with the requirements of road signs and markings.

If you received a “chain letter”, then with a high degree of probability the violation was recorded by “Strelka-ST” from the company “Systems of Advanced Technologies” - one of the most common photo and video recording systems, which, like the above-mentioned guards, is capable of not only determining the speed of movement , but also to distinguish between traffic in the oncoming lane, the side of the road, a public transport lane, record the rules for violating the passage of intersections, driving beyond the stop line, and even moving freight vehicles in prohibited places.

According to some reports, Strelka-ST does not have time to catch a car moving at a speed of over 180 km/h, but it has a kilometer range and detects a violation at a 500-meter distance.

The Simikon company previously produced KRIS-S complexes, and now produces Kordon in stationary and mobile versions. It is not only “rapid-firing” - it catches vehicles up to 300 km/h, but it also records everything in the control zone, that is, it is trained to determine the pace of movement in all lanes in any direction.

Note that among the variety of options, there is a complex that determines the average speed on a traffic section.

So, how to outwit speed detection systems? Let's not be original - don't break it. Some use smartphone apps with a database of installed cameras, which warns in advance of the risk of being fined. Having passed the camera, they fly further again. Do you do this too? Remember that the Rules are mostly written in blood, and racing on public roads usually ends badly.

Today, three video cameras for recording violations are most widely used on Russian roads. We are talking about the KRIS, Arena and Strelka models. Now let's talk about each of these cameras in more detail.

The CRIS mobile complex is widely used throughout the country. The equipment can be placed on a car or on a special tripod. The high mobility of the complex is “compensated” by its obvious weakness. The range of the CRIS is only 150 meters. The range of fixed speeds is 2-250 km/h. Violations are detected using an infrared sensor at a distance of 50 meters. At the same time, in some cases the car can get into the fixation base at a distance of 100 meters.

A more advanced and “evil” complex of video recording of violations on the roads. The main feature of “Arena” is that it is always directed in two directions and can receive data from both “front” and “behind”. In other words, even after successfully passing this camera, there is still a chance of getting hooked on it. Moreover, the range of the equipment is 300 meters. The range of fixed speeds is 20-250 km/h. Violations are recorded only on straight sections of the path at a distance of 100-150 meters. There is also a portable version of Arena. This camera usually runs on a battery that lasts for 8 hours.

A real “witches’ hammer” aimed at reckless people. The most advanced and advanced camera available today. According to some reports, Strelka was developed as equipment for fighter aircraft, but the system later found application in the civilian environment. The main advantage of the Strelka is that, unlike most other cameras, it is capable of tracking 5 targets at once. Thus, hiding from Strelka is, if not impossible, then astronomically difficult.

The detector camera recognizes traffic at a distance of up to 1000 meters. The accuracy of data acquisition is 2 meters. The complex is configured to detect violators in speed ranges of 5-180 km/h. You can't hide from the camera in traffic. It is not known at what exact distance the violation is recorded, but the camera will “guide” the car until it approaches 50 meters.

How do speed cameras work?

Cameras for photographing traffic violations are becoming more and more numerous from year to year, and the list of violations that such a camera with advanced software can record is also impressive. Moreover, all cameras, without exception, are designed to record violations of the speed limit. This scale of placement of cameras is due to the fact that the technology is impartial and objective in comparison with traffic police inspectors and there is no way to come to an agreement with it, although sometimes the cameras also misfire and record “pseudo-violations.”

How and on what principle do speed cameras work? How many meters away do cameras record speed violations? Do speed cameras work at night? On what principle do average speed cameras work? We will answer these questions in this article.

How cameras work on the road

The basic principle of operation used in most cameras is based on the use of the echolocation method, which involves receiving a number of signals reflected from vehicles on the camera matrix, after which the system calculates the distance covered by the vehicle between the signals and calculates the speed using a mathematical formula.

New generation traffic cameras, just appearing on the roads, conduct photo and video tracking and, at the same time, calculate the speed of vehicles in motion. There are also cameras whose operation is based on a laser beam, the impact of which at one angle or another makes it possible to calculate speed based on the equations for the Doppler effect.

The cameras themselves can be:

• stationary. They are installed once at a permanent location and do not freely change their location;
• mobile. They have the ability to move freely, so they are used on different sections of the road, depending on the task. This type of cameras includes radars on police service vehicles, cameras mounted on tripods or in hands, and covert surveillance devices.

Photo recording cameras (stationary) operate around the clock. Night time does not interfere with recording violations, since they are equipped with infrared illumination.

Operating principle of average speed cameras

The speed of a moving vehicle can be measured as average or instantaneous. It all depends on the functional features of the camera and software. In the case of measuring average speed, a set of radars is used, located on a certain section of the highway.

Avtodoriya complex

Calculates the average speed on a certain section of the road, which can be either a couple of hundred meters or reach several kilometers. These complexes do not contain a radar part. In fact, at the beginning and end of the calculated section, photographic recording is made, which is designed to record the time interval between the moments of being at given points. The system knows the distance in advance. Given two variables, the system will automatically calculate the average driving speed. Even such a seemingly simple system fails. The fact is that cases cannot be completely ruled out when, given the similarity of cars and their license plates, the system identifies objects as the same transport, as a result of which, if both drivers do not have an offense, one of the car owners may receive an unfounded letter from fine

Vocord system

For this system, one camera is enough to determine the average speed of transport, since such cameras take several pictures in a row on a certain section of the road. Radars are also not used for these systems, but due to the limited distance at which photographic recording and calculation of the object’s speed takes place, the result obtained will be as close as possible to the actual speed.

Complex "Avtouragan"

The complex’s cameras calculate the speed of an object’s movement using a “certified optical method from a video image,” which is a measurement of the parameters of the observed object in the frame. The object is not the parameters of the entire vehicle, but only its license plate.

Radar "Cordon"

During fixation, the radar simultaneously recognizes the vehicle license plate, determines the coordinates and calculates the speed.

Despite the variety of video recording systems and complexes based on different operating principles, there is no universal complex that works without failures and errors. The main reason for such errors is problems in the software, most often these are caused by viruses and glitches, but there are also more prosaic ones - for example, weather conditions that influenced the change (shift) in the location of the camera.

Distance sufficient to record speed

The distance from the camera sufficient to record speed depends, first of all, on the type of photo-video recording system. Weather conditions, time of day, etc. play an important role. If the system consists of several simultaneously functioning cameras of the Avtodoriya type, then the distance can be measured in several kilometers.

If the complex consists of one independent camera, then a moving object falls into its field of view approximately 450-500 meters from the camera. This is the maximum distance under ideal conditions (light, clear, clean lens, etc.). A violation can be recorded while the object is in the camera’s field of view, i.e. getting into it 450-500 meters away, a few hundred more meters are monitored and the speed is calculated. In case of violation, photographic recording is usually carried out at a distance of 50-70 meters from the camera mounting location.

Maneuvering on a section of the road monitored by a camera before the final photo recording, such as changing lanes from lane to lane, leaving the visibility zone (changing lanes behind large vehicles in front) assumes in theory that the system will forget the violator. But often the obtained results of the violator’s speed are assigned to other vehicles that are moving in the vicinity of the violator, and in fact, an innocent person receives a letter with a fine. A similar situation is with motorcycles, the license plates of which, as a rule, do not fall into the field of view of the cameras due to their placement, but when moving with speed limit violations in the vicinity of cars, the system mistakenly records violations, but not of the motorcycle driver, but of the driver of the neighboring one. car with him.

Conclusion

Despite the flaws of the cameras, in fact today this is the most objective, impartial and incorruptible of all existing methods of monitoring compliance with traffic rules. Attempts made by drivers who like to drive around on the road do not give the desired result. Stickers, sprays and other manipulations with license plates, as a rule, do not create obstacles for cameras, but detection of such facts by inspectors can lead not only to a fine, but also to the deprivation of a driver’s license.

How many meters before the car do cameras start recording speeding?

To record traffic violations, bulky units attached to patrol cars and hand-held radars have not been used for a long time. They have been replaced by high-tech recording cameras, characterized by high resolution and a host of additional functions.

Many motorists ask questions: at what distance do devices begin to record speeding and what else are high-tech law enforcement officers capable of?

The capabilities of the latch depend on its modification. There are several of these:

1. “Chris”, “Arena” are the simplest models. They make up the bulk of road surveillance devices. Radars are capable of detecting an intruder at a distance of no more than 100 m.
2. “Cordon” and “Krechet” have more power and recognize reckless drivers at a distance of 150 m. Cameras record both approaching and retreating cars. They are very rare on the roads.
3. Strelka is the most forward-thinking surveillance camera. The coverage area of ​​the Strelka radar is 250 m.

The fixed distance also depends on external factors: weather conditions, time of day, etc. There are systems consisting of several cameras located in a row. Their coverage area depends on the number of devices. In certain cases, it can cover kilometers of travel.

Photo recording of the offending vehicle occurs at a distance of 50 to 70 m from the location where the fixing device is attached. Experienced reckless drivers, getting into the radar zone, begin to maneuver.

The response of the fixator depends on its technical capabilities. The surveillance system can simply “forget” the reckless driver. But often the cameras get confused and photograph the license plates of cars driving nearby. Thus, a completely different driver receives a fine.

It's the same with motorcycles. Photo recording devices do not have the technical ability to recognize the license plate of a given vehicle. Therefore, the car that was closest to the motorcycle at the time of photographing receives a fine for speeding.

Despite all the imperfections, the road surveillance system is the most impartial and incorruptible way to monitor compliance with traffic rules. Some drivers try to deceive it by changing license plates using spray, stickers, etc. But speed control devices, as a rule, still recognize the car, and cunning reckless drivers risk losing their driver's license.

At what distance do cameras see violations?

Cameras are everywhere now. They are configured to detect a wide range of violations and show incredible efficiency. However, such close attention often annoys drivers, causing them to be tense and make more mistakes. You can see how confused drivers, when they see the camera, reflexively slow down to 60 km/h in places where they can go 90 km/h, thereby creating obstacles for traffic. Others, on the contrary, try to rush along the road at a serious speed limit and try to hide from the cameras with buses or minibuses 50-100 meters away in order to sneak along the public transport lane.

In order to safely interact with data center cameras, not to be afraid of them, but, on the contrary, to concentrate on safe driving, you need to know the operating principle of these devices, so as not to be fooled in vain and not to attribute miraculous properties to the cameras.

Conversion Product

There are three types of cameras that have been adopted by the traffic police and are now replacing outdated types of monitoring devices. These are the KRIS, Arena and Strelka radar systems.

The most effective system for recording violations is considered to be the famous “Strelka”, which has made significant progress in the administration of an entire traffic flow. In its work, Strelka is fundamentally different from its previously existing foreign and domestic analogues. The control system was developed on the basis of military radar guidance systems for aviation, used to work against several air targets at once. Military developments turned out to be applicable for civilian use.

The Strelka ST01 camera-detector recognizes the speed of vehicles at a distance of up to 1000 m with an accuracy of 2 km/h. The minimum measurement range is 50 m. The speed range for which the complex is configured is from 5 to 180 km/h.

However, recognition of license plates of violators’ cars and their photographic recording is carried out at a distance of no more than 50 m. It is at this distance that the lens focuses and infrared illumination is used.

At the same time, the stationary “Strelka ST 01” monitors the entire traffic flow and is capable of simultaneously monitoring the entire section of a multi-lane roadway within a range of up to 1 km. Its radar can track dozens of targets simultaneously.

Thus, Strelka ST 01 sees intruders even before they can distinguish the mast with the device. However, photographing a car and recognizing it occurs at a much shorter distance, and without such recognition a fine cannot be issued.

Tripod in action

The Arena complex is used by the traffic police and road services much more often than Strelka. This is a well-known “tripod”, which even caused criticism from President Vladimir Putin . It is this device that private companies that have contracted for the maintenance and operation of control cameras love to hide in the bushes.

The Arena device is equipped with a remarkable camera that can look into the car’s interior and recognize the facial features of the driver and front passenger. In this case, speed control can be carried out not only from the front, but also from the rear. That is, “Arena” fires an impulse first forward, and then can duplicate it after the car has passed in order to control compliance with the speed after meeting the camera.

Arena operates at a distance of up to 300 meters and can only track cars in line of sight. Therefore, due to the low location of the “tripod”, its actual control distance is reduced to 100-150 m.

The device records speed in the range from 20 to 250 km/h with a measurement error of 2 km/h. In this case, the camera can determine the speed of cars only in the two nearest lanes. You rarely see her on multi-lane highways, since she cannot see the high-speed lanes and gets confused in her readings. The continuous operation time of the complex depends on the battery. A standard charge lasts for 8 hours.

Mobile CRIS

There are other speed control systems. For example, the mobile device KRIS is very similar to the “Arena”, since it is also installed on a “tripod”, but can also work on cars. It is less functional than the systems described above, since it monitors only one lane, and the range is limited to 150 m. The range of measured speeds of the CRIS is the same as that of the Arena, that is, from 20 to 250 km/h, however, The measurement error is 1 km/h. Photographing the car takes place at a distance of 50 to 100 meters. At night, the camera can identify the car by infrared illumination, which operates at a distance of up to 50 m.

Thus, all complexes photograph the target at a distance of 50 m, but they can track at a much greater distance.
