DVRs are very popular devices and today we will talk about how to choose them correctly and what to pay attention to.

Many buyers believe that choosing a DVR is very easy and many just have enough FullHD inscriptions on the box to make the final choice. The fact is that many naively believe that if such a shooting format is supported, then it will be of excellent quality, but this is far from the case. We decided to figure out what to pay attention to when choosing a registrar and how not to overpay for excess functionality.
How to choose the DVR correctly - by what parameters?
When choosing a video recorder, you must take into account different criteria, and not one specific one. Let's figure out what you need to look at and talk about each of their criteria in more detail.
1. Cost
The very first thing you need to look at, oddly enough, is the price. You must clearly define your budget, as well as the final functionality that can satisfy you. Immediately keep in mind that very cheap models cannot work perfectly and can even let down. Although it doesn’t mean better, it’s completely different here.
It turns out that even the most expensive model can work with errors. But still, remember one thing - an expensive device with a high degree of probability will be able to record high -quality video, which, if necessary, can be used as evidence in court. Thus, the very first thing you should understand is that you cannot save on the registrar.
2. Fastening
Many motorists think that the main criterion for choosing is functionality, only this approach is wrong. In fact, the main criterion is the fastening, because it will be it that will hold the device more often. By the way, it can be judged by the quality of the device. Fastards today are of different types.
- DVR on the suction cup
Such models are convenient when you constantly have to remove the device to take it home with a radio. Today, more and more often cars began to hack and accordingly steal from them everything that could be of value.
By the way, DVRs are the most popular in terms of the number of thefts, especially in courtyards and nearby territories. Therefore, if you do not put your car on the parking lot, then select the model with suction.
- DVR with adhesive tape
This mounting method does not allow the registrar to constantly remove and return to the place. If you have chosen just that, then make sure that it has the ability to change the tape, because you will have to do this often. Although, if you think about it, the suction cup fixes the registrar is somewhat worse than the tape, so think about which option will be convenient for you.
When choosing a new device, first of all, take into account where exactly you put your car and only then decide what kind of fastening to make for it. By the way, make sure in the store that it is reliable - check the foot, twist it. The clarity of the shooting depends on the length of the mount. So, the longer the holder, the worse the record will be, because the registrar, albeit imperceptibly, will hang out.
3. The class of the DVR
So, as you understand, vibration depends on the fasteners when the car moves and this directly affects the image quality. However, car chambers differ in classes. This also needs to be taken into account before buying.
There are several nuances. For example, if you live in a big city where the movement is very large, unlike small populated. In the last situation, you can choose a cheaper option, because drivers in provinces are more disciplined than in large megacities.
- Budget DVR
The name already speaks for itself. In this case, we are talking about simple devices with the lowest price. Each of them has only one camera, one microphone, and there is also a slot for a memory card. Undoubtedly, such devices are often bought, if only because they are cheap, only the quality of the shooting makes you want the best.
The resolution of such devices usually does not allow to normally record everything that is on the road. The shooting will be carried out only in front of the car, but sometimes you need a view from the side or behind. Often it turns out to be very important. Although cheap devices have certain disadvantages, people still buy such models with hunting, based on their low price.
- Multifunctional DVR
A fairly interesting class of devices with which you can record a picture with sound, and also control the different indicators of the car. For this functionality, they were nicknamed "black boxes."
So, for the moderate cost you can get a whole information gadget and you can prove your case with it in any situation. In addition, you will additionally receive other useful data:
- The coordinates of the location of the car
- The speed of the machine at a specific time
- A large viewing angle that allows you to see everything on the road
Like any video recorder, these models are attached on the windshield, although some options have also cameras connecting to other places of the car. Undoubtedly, the cost of these devices is much larger than budget, but they also give much more.
- Kamkoders - universal DVRs
At one time, people made recorders from ordinary video cameras, only this idea is very bad, because the household camera is not able to give a normal shooting angle, which should be approximately 130 degrees. They will not be able to give the required angle, and, accordingly, write down all events on the road. So if a similar thought visited you, then immediately drive it away. Moreover, registrars today have quite affordable prices.
- Professional DVRs
This is the last class worthy of attention. Such DVRs are full -fledged devices that display what is happening around the car and record high -quality pictures. Among the mandatory functions of professional models stand out:
- GPS receiver
- Internet connection
- Several cameras and microphones
- The ability to use several memory cards
Separate models can even be recorded on an external hard drive. Moreover, they take into account the operation of the car systems, speed and even acceleration. It is important to say that the quality of shooting here, regardless of time, is always on top. The main disadvantage of the device is the high cost.
As you can see, registrars are divided into different classes and this is important to take into account when choosing a suitable device. In practice, ordinary drivers choose models with a large set of necessary functions at an affordable price.
4. The characteristics of the DVR
So we got to the most interesting - characteristics. Each person understands that technology, whatever it is, may differ in functionality. This also applies to DVRs. Each of the devices has its own set of functions and when choosing you should proceed from its needs.
- Camera angle
This is one of the most useful characteristics that depends on what exactly you write down on the road. Most models work in the range of 100-150 degrees. Here it must be borne in mind that the larger the angle, the more it falls into the frame. So, the device can even capture what is happening in the next strip. Judging by the reviews of drivers who have already got into an accident on the road, the best angle is 120-130 degrees.
- Resolution of the shooting
Everyone knows that the video is recorded with a certain resolution. It is believed that the optimal for the DVR is:
- SD - resolution is one of the low and is 640x480 pixels
- HD - high resolution of 1280x720 pixels
- Full HD - the highest resolution of 1920x1080 pixels
Of course, the higher the resolution, the better. However, with it it becomes higher and the price of the registrar. It is also important to understand that the image will occupy more memory. So if you select a camera with Full HD resolution, then do not forget to buy a large memory card. The average option is HD. It gives good resolution and is not very expensive.
- Video recording speed
In this case, we are talking about the number of frames per second. Their optimal amount is 24. If this value is lower, then the image will be inhibited and very low quality. However, technologies walk far ahead and therefore there is the opportunity to choose more frames to make it more convenient. It is clear that the more frames, the better. The quality of the video from this will only be higher, but the cost of the product increases.
Today in many cameras several options for choosing a recording speed are being built at once. So, the owner can choose any convenient and use it. Manufacturers today can offer devices even with 60 frames per second, but this is only a figure and nothing more. In fact, the best image quality is achieved only at 30 frames per second. So be careful when choosing registrars, because you can run into a “trick”.
- Number of chambers for recording
DVR may not have one, but several cameras. Undoubtedly, the more there are, the better. This will allow the driver to receive information about everything that happens on the road. Just keep in mind that the main camera takes 24 frames per second and in HD format. If an additional lens is included in the work, then the overall performance will decrease. However, this applies to cheap models.
Although, despite this drawback, many cameras still help out well in difficult situations on the road. The fact is that the review becomes wide and therefore it is possible to control the situation from all sides.
- Cyclicity of video recording
This is another point that you need to pay attention to. Of course, if the recording is carried out constantly, then it will not be possible to do with only one memory card, because there will be a lot of data. So manufacturers have created cyclicality, which allows you to break the file into different parts.
Basically, the record is from 2 to 30 minutes. During operation, the files will be accumulated on the card, and when the memory is filled, the first file will be rewritten and so on. In fact, drivers do not need data on all movements, but only for a certain time. Although, cyclicality can be turned off if it is not needed. For example, it will be useful when learning to view your mistakes.
- Microphone
Today, almost all registrars can record sound. It may also be important in a critical situation. By sounds at the time of the accident, you can understand whether there are braking distance and other details. At the same time, the microphone should be of high quality and record everything that happens.
Sometimes it can be useful to record a conversation with the inspector. The camera will always fix unlawful actions and so on. Before buying the device, ask to show it in the case.
- Memory cards
Memory cards may differ in volume and if you want to use average or maximum, be sure to pay attention to how much it is available for a particular registrar. If the largest thing is available for the registrar - 32 GB, then 64 GB will already not be inserted.
There are models with additional memory cards, and a record on an external hard drive can also be available. Be sure to consider these points when choosing a registrar, so that later there are no problems.
- Internet support
The Internet today is in our life everywhere and without it now. DVR manufacturers are also aware of the trends and today there are models with Internet access. This is possible due to the presence of a 3G module. In this case, you can conduct direct broadcasts or send a video to another device. This will allow you to record everything that happens and data will always be in one place. The only drawback of this approach is the need to pay mobile communications.
What else to pay attention to when choosing a DVR?
Undoubtedly, it will not work to talk about absolutely all DVRs in the article, because there are a huge number of models. However, some obvious points must be taken into account.
- First of all, make sure that the device is with the ability to connect to USB. This will allow you to connect to the on -board computer of a car or PC.
- Pay attention to the models of registrars with an external screen in the design. It can be useful when you need to quickly navigate in the situation and you can do it directly through the registrar.
- The presence of GPS and G-sensor is important. Together, these modules allow you to create a complete picture of events with coordinates and acceleration.
- The function of the movement detector is very useful. In other words, when a movement occurs in front of the car, the recording is activated. This allows you to save space on the memory card and conduct night shooting when it is necessary or in the parking lot.
- There are also rotary DVRs that can at the right time move the focus from the road to the inspector.
Which one to choose the manufacturer of the DVR?
There are more than a hundred brands on the video recorder market at the moment and all of them offer models in different price categories. It is Chinese devices that are in great demand in Russia. Their number of the total number of equipment is 50%.
Previously, China was perceived very poorly, because the products from there went, to put it mildly, of poor quality. But today it is very good, reliable products. Often brands offer models in a wide range of prices, starting from budget and ending with premium. Customer reviews about such products are very good.
The Russian company Datakam itself creates devices and collects them. Products are of high quality and are able to offer good functionality.
Another Russian brand is Avtocam. This company itself creates devices, but the Chinese collect them. The assembly is at a high level and does not cause complaints.
How to choose a DVR: Useful tips
Learn to distinguish useful functions from extra. For example, GPS, a motion sensor and accelerometer can be useful, but LED backing is unlikely to be useful. It does not shine very far, and can give glare, which is why the quality of shooting worsens.
Carefully study the characteristics of the device. If Full HD is written in the description, then it is not a fact that it really is. Check with the seller how it turns out. It happens that the device has a HD camera, and high resolution is obtained due to interpolation.
It is optimal to choose a model that has a built -in battery and a removable hinge. This will be useful for shooting a dialogue with a postal employee or damage to a car. In devices of average cost, there are usually batteries, which are enough for half an hour of work.
Do not be afraid of Chinese products. In quality, it is no worse than other countries, it all depends on the price of the device.
And the last thing you should take into account is the length of the power cable. The fact is that the registrar is connected to the cigarette lighter and the wires should be enough not only before it, but also in order to hide it under the panel.
