Growth of traffic on our roads does not guarantee even the most law-abiding motorist accident-free operation of the vehicle. Even with the most accurate driving and strict observance of traffic rules, the risk of becoming a participant in a road accident is high enough. At least for a reason, completely beyond our control.
Most of these trials literally "exhaust" both strengths and nerves. But this is not the most depressing drivers. The main difficulty is that it is not always possible to prove that you are right. That there are no adequate witnesses, then the inspector( and about the corruption of many of them have long been jokes) a priori stands on someone's side.
Perhaps this is the primary reason for the growth of popularity of such devices for the car, as DVRs. This impartial eyewitness is able to give a true picture of all that happened and help out in a difficult moment, in any disputable situation, and often directly on the spot, thus exhausting the incident at the very beginning. The main thing is to choose the right variant of the DVR among the huge assortment offered by the market.
For this reason, it makes no sense to do a comparative analysis of DVRs depending on their cost. But what should first pay attention to, then not be disappointed - the subject of a detailed investigation. And the talk will be about "amateur" models, since devices with several cameras, enhanced functionality are quite expensive, and ordinary car owners are unlikely to be interesting and needed.
The main criteria for evaluating the DVR
Viewing angle
The optimal option is within 130º .With a smaller angle is not worth buying, since such a camera can not record everything that happened on the side of the car at the time of the accident, and this sharply reduces the chances of a fair trial.
We can assume that the higher this numerical value, the better, but this is not entirely true. The fact is that as the possibilities for review increase, the quality of the "picture" decreases, which means that some small details that are extremely important in the given circumstances can be missed( or badly displayed).This is the inverse relationship. Well, about the smaller angle and it is not worth talking about - it will only cover the oncoming lane, which is also unprofitable from the point of view of obtaining reliable and complete information.
Resolution of
This parameter directly affects the clarity( quality) of the image. Of course, if we are going to shoot an amateur film and send it to the contest, the requirements for permission must be increased, otherwise the "Oscar" will not get exactly. But there are several points that limit the choice. First, the more "pixels", the higher the price of the device( and its growth is very significant).Secondly, for better recording and a memory card must be appropriate.
Some products made in China use electronic interpolation techniques to improve shooting quality. Judging by the advertisement, no other model will give the best picture."Vesti" on this is not worth it, especially if there is not the slightest idea of what the "essence of the matter" is. The principle is effective in itself, but its implementation in the DVRs does not provide the proper image quality.
Speed of shooting
Here it is necessary to focus on yourself, on the manner of driving. The higher the write speed, the less likely that the device will not have time to fix something. But an increase in this indicator entails an increase in value( since the card will also need "more volume").Models with very high speed( and therefore, the price) are more suitable for those who believe that the brake pedal was invented by a coward. For a normal motorist, it is enough if the DVR is designed to record 20 - 30 frames / second .
For example, an HD recorder will not be able to write at a speed greater than 30 fps, even if it is labeled as 60 on the passport. For this faster recording, you need an SD card with a high write speed. Here on such little things we often "catch", but in practice we overpay for what exists only in theory.
"Cyclic"
In fact, this characteristic reflects the capabilities of the device for the duration of continuous video recording. 1 file is designed for a period of 2 to 30 minutes .This is set by the user. After such electronic "sheets" are typed a lot and the memory of the device will be filled, it is cleared, and the video is written on the blank "pages of the notebook".Here you need to focus on the range, duration of travel. As a rule, half-hour cyclicity is quite satisfied with most motorists.
Number of cameras
The opinion that the more of them, the better the registrar, many are misleading. For professional photography this is really important. But to fix all the stages of the "auto" movement, only one thing is enough. It should be borne in mind that all cameras are "loaded" onto one electronic circuit. Even if there are only 2 of them, the quality of shooting for the second will be approximately halved.
Although only 1 camera significantly limits the possibilities. For example, you will not see the space behind, for example, during parking. But the minimum - a record of everything, then occurs in front of the machine, it fully provides.
Audio mode
Probably, to write down "for descendants" all sounds during movement there is no sense. But here "to capture" a conversation with a traffic police officer or too violent participant in an accident( just in case) - insurance is not superfluous. Therefore, such a function is really useful and necessary.
Attachment
"Suction Cup"
This option is more "long-playing", since this method of fixing the recorder allows it to often be removed and, if necessary, installed in place. This is good when the car is left parked for a long time or stored in an open area. I removed the device, and the problem of the theft of the device was solved. The disadvantage is that such fastening is not reliable enough. For example, when driving over rough terrain, the recorder can easily "fall off".Break up - it's unlikely, he'll just hang on the cable. But it will have to be reinforced again, and at the same time to waste time.
"Velcro"
This fixation is more reliable, but if the device is constantly removed / put, then the tape will not last for a long time. The optimal option for those who mainly moves, for example, on the familiar route "garage - dacha - garage".
If during the movement the camera will vibrate, then you can not even dream about high-quality shooting. Therefore, inspecting the mount, you need to make sure that all of its connections are reliable, and there are no different "loopholes".
As with any electronic device, you can talk about DVRs for a long time. But if a person understands modern technologies, knows what a USB port is and does not confuse it with GPS, then he does not need to explain - all the necessary information he will find in the passport of the device. The main parameters of the registrars we noted, and this is enough to make the right choice and be sure, in any situation such a "witness" will not fail.
