DVRs

Given the ongoing lawlessness on our roads, including that of the traffic police, the popularity of DVRs is not surprising. YouTube is full of clips of cases on Russian roads, and in fact DVRs are not as popular in the world as we do. In general, this class of devices is not taken seriously by many, stereotypes and myths develop about their work.

It is unclear whether it is possible to use the recording from the DVR in the court, which resolution is better to choose? In addition, several hundred different models are on sale, each of which emphasizes its strengths. And this is even more confusing. So it’s time to deal with the basic myths about DVRs.

DVRs

To shoot at night in the DVR set infrared illumination.

Actually, the functionality of such a backlight is somewhat different – it is needed to improve lighting a few meters away in the direction of shooting. Most often this is required when it is necessary to distinguish the faces of people who are in close proximity. So, if at night the car is stopped by the inspector of the traffic police, you can deploy the recorder and turn on this backlight. As a result, noises will leave the picture, and the image will be quite acceptable. Illumination will be useful if you have to shoot outside the car at night. And for night shooting in motion it will be better to choose a recorder with a system of glass lenses. Such optics show themselves much better in conditions of poor illumination, compared to conventional devices with plastic lenses. And infrared lighting today is quite common in DVRs.

The wider the viewing angle, the wider the picture captured when shooting.

And although this point is not the most needed today, for many it is still important. Yes, and the angle of view of the manufacturers began to point not horizontally, but diagonally. In fact, this is a marketing trick that allows you to mislead the buyer. An honest parameter of 120 degrees can only be obtained if the aspect ratio of the picture is 16 to 9. If they are correlated as 4 to 3, then together the roadside and traffic lanes the camera will show unnecessary pieces of the sky. It is necessary to select such devices that give a “wide” resolution of 1280 * 720 or 1920 * 1080 when shooting. If the DVR promises 1024 * 768 pixels or even 640 * 480, then it is better to refuse such devices altogether. The latest models of well-known brands guarantee a real wide viewing angle.

Excellent recording quality is possible with Full HD resolution.

Those who worked with DVRs are familiar with the concept of interpolation. It is resorted to by “gray” devices of unknown manufacturers or fakes for famous models. To save on components, the creators put cameras with low resolution. And then, with the help of interpolation, the picture is simply stretched to the desired resolution. So, from the VGA 640 * 480 image you can get HD or even solid Full HD with 1920 * 1080 pixels. The user will be surprised why his camera, with the claimed high performance shows cloudy videos. So before buying a DVR, especially a little-known company, it’s worth looking for videos from it posted on YouTube. Then it immediately becomes clear that the device is really capable and how much it corresponds to what was declared on paper. It is obvious that self-respecting brands do not resort to interpolation.

Data from the GPS receiver of the DVR can be used as evidence in court.

They can confirm the speed of movement or the location on a certain lane. You should not believe in magical orbiting satellites that can help. In fact, our user electronics with built-in GPS-receiver still gives a considerable error in the precise determination of coordinates. As a result, the accuracy of the location is determined with an error of up to 7 meters. To this should be added and interference in the city, where a fairly dense building.So it turns out that it is quite difficult to read data from the GPS receiver of the DVR as reliable in terms of specifying the coordinates of the car at a certain point in time. In addition, it should be remembered that if video recording and the subsequent use of this record do not provide for mandatory certification of the device, its use as a measuring device (speed and location determination) will require the presence of such status. But the presence of GPS in the DVR will be useful in another connection. This module is usually combined with a radar detector. As a result, the driver receives warnings about the discrepancy between the speed of his car and the established norms. In some registrars, it is possible to transfer the GPS coordinates of the route to map services in order to memorize the traversed route.

If you leave the DVR in the cabin, then it can scare off thieves.

Actually, this not only does not scare away, but even attracts intruders. After all, if you plan to rob a car, in the first place will be chosen exactly the one in which there is a DVR. The stolen device can not tell anyone about anything, but a thief can come in handy. Even a miniature DVR in the presence of a fastener in the cabin will be found quickly. The thief will understand that somewhere in the cabin is located such a device.

If you leave the accelerometer on (G-sensor), then it will quickly clog memory with unnecessary files.

This can actually happen if the default settings are enabled in the recorder. Accelerometer is needed to work at overloads. This is directly indicative of accidents. In this case, the current record is placed in a specially allocated area of ​​memory, where it remains, being excluded from cyclic rewriting. Thus the video will be saved. But the settings of the DVR by default can become such that the accelerometer will work from every bump. To prevent unnecessary operation of the sensor, you must adjust it by lowering the sensitivity threshold. Such settings are usually in the registers with the G-sensor.

If you put in the car DVR, then it will remove everything that happens on the road.

There is one important feature that unscrupulous producers are silent about. The fact is that the registrar writes clips with a certain length – from 1-2 minutes to 10-20. Well-known manufacturers are trying to ensure that not just a second is lost between the rollers, but that they are also “overlapped” – the new video should include a few seconds of the previous one. But practice shows that there are models that can lose from 1-2 to 10 seconds when creating a new file! This suggests that the registrar can “fall out” of the process at the time of the accident, so nothing and not filming. But this happens only with the cheapest models – an extra reason not to save on such a device.

The court must take into account any video from the registrar.

Another version of this myth says that the decision to attach a record from the registrar to the case is taken by the judge individually on the basis of personal considerations. In fact, in the same “Code of Administrative Violations”, which operates in the territory of Russia, it is clearly stated that any information obtained by any methods can be used as evidence in the investigation of road disputes. Of course, this includes any analog, digital video or audio recordings that somehow can shed light on the circumstances of the case. Of course, the employee of the GIBD, who is handling the disputable situation, or the judge may well have questions about the authenticity of the record. Then there is a technical expertise that can prove the truth of such material. The record itself can not mean anything, it must be evaluated together with other materials. It happens that witnesses are confused, lying or mistaken, which is excluded in the case of a video. That’s why trust in such materials should be more than people or employees of the road patrol service.If the court refuses to attach a videotape to the case, it is necessary to demand a written confirmation of this with a mandatory indication of the reasons for such a decision. Sometimes, even a request for motivation for refusal prompts the court to reconsider its point of view without even appointing an examination. And to force the court to believe in the truth of the record, it is necessary to transfer the carrier to the DPS officer right on the scene of the incident. And it must be done in the presence of witnesses. The fact of media transfer must be reflected in the protocol, specifying in detail its technical characteristics. For a memory card, this will be the manufacturer, volume, class.

To consideration, not digital but only analog records with a frequency of 25 frames per second are accepted in the court.

This is a fairly old myth, which appeared at the very beginning of the era of distribution of DVRs. At that time, the experts had worked with only analog recording methods. In modern realities, digital records have long been accepted by the courts in the manner described above. And the most modern DVRs are shooting at Full HD resolution at a rate of 30 frames per second.

If there is a DVR, then traffic police officers are no longer needed to register an accident.

This statement is only half true. In fact, motorists can solve the problem themselves without an inspector of an accident, and without a DVR. To do this, the participants of the incident must fill out an “Accident Notices” form and depart. This is allowed if the accident involved no more than two cars, there are no injured people, and the amount of damage does not exceed 25 thousand rubles. However, the participants themselves do not argue about who is guilty. This method refers to the “European Protocol and has been in effect in Russia since 2009. That’s only according to statistics, the police still cause in 29 cases out of 30. The authorities are planning to introduce an expanded version of the europrotocol as an experiment. These conditions are supplemented with a clause limiting damages amounting to 400 thousand rubles. Required and mandatory video from the registrar. The model should be equipped with accelerometer and GPS modules. So insurers maximally protect their money from scammers. That is why the acquisition of the most advanced registrar with a multitude of functions and sensors can be a good investment for the future.
