🚗 How to buy a DVR: review of models and guidelines for choosing the

How to choose an inexpensive but good video recorder

Now Video recorder It is a very sophisticated electronic device inside which has its own processor, memory, analog-to-digital converter, a microphone and other components. Naturally, from the model to the final characteristics can vary greatly. To understand why we need this or that option, you need to know how they work and understand which component is better suited for this configuration.

In intellectual performance

The system is steadily becoming smarter every day. The new processor, a new type of memory, other innovations open up new possibilities for the implementation of intellectual abilities techniques. Man, far from technology, it is not always easy to understand how to operate this or that novelty, since the actual mechanism of yesterday can already significantly out of date today.

The properties of the matrix and Optics

Although the optics and signal conversion system in digital form is very difficult to understand when choosing a device for themselves in this very not necessary to delve into them. Under the DVR understood matrix array of pixels, which are able to detect light and convert it into a digital signal. The quality influences the size of the matrix itself - the larger it is, the more external data it can capture. Hence, the output we can get a clear and detailed picture. That is, if you select the DVR, better to give preference to the model that the matrix area more.

It is designated, by the way, in fractions of inches - ¼ "or ⅓".

As for optics, above all, pay attention to the angle. The wide-angle lens can capture a large area in front of the camera. It is very convenient to take pictures around the sides of the car. However, it should be borne in mind that a large angle will produce distortion - the effect of "fish eyes". Therefore, there is better to choose a middle ground. From optics materials is better to give preference to glass. In contrast to the analogues of plastic, glass transmits light better.

The frequency of the recording and resolution

Perhaps this is the very first options when selecting which users pay attention. In general, it is possible to navigate and understand how a device produces high quality picture. Resolution - the number of points that can come after the actual signal conversion to digital format at the output. The higher the value, the better. Feature specifications are usually indicated as a 1024 × 768. First, the number of pixels horizontally, then vertically. Sometimes near the value of the vertical can be letter i or p. This type of scan. The first means interlaced, and the p - progressive. When progressive scan each frame contains a full set of rows. When interlaced half-frame is formed, which can be used for half of all rows except for the odd or even-numbered. It follows that the progressive scan produces better picture.

Frame rate - the number of frames per second. For the analysis of the situation on the road is very relevant parameter because it allows a detailed, frame by frame to consider any accident or incident. frequency values ​​typically found 15 to 60 frames per second. It should be remembered that the high frequency requires a larger storage volume, as the size of the resulting file will be larger.

The conclusion of the work on the car's screen reading and GPS-navigator

View the status of units of the car is quite expensive additional functionality. For this possibility the vehicle must have the support of this functionality, and the registrar should have sufficient size monitor. The same applies to the navigator. The DVR must have a GPS module and an appropriate monitor for easy output. Model "all in one" will cost quite expensive. It will be easier to select recorder with video outputs and inputs, to which in the future will be to connect other devices to diagnose or navigation.

Settings Memory Card

To record data on a memory card convenient to use. If necessary, you can quickly retrieve and view video media on your computer or other device more convenient. Memory cards are different capacity and recording speed. The above two parameters, the more expensive card. At the same time, it is possible to record a large amount of content in the best quality. write speed is also relevant for saving movies in high quality with a great value in the second frame.

Extra features

The DVR can also possess additional functionality that is not required, but makes managing and operating the equipment easier and more convenient.

• autostart. The function can be called in different ways, but the essence of it alone - when starting the engine, the recorder automatically starts recording. And when you turn off, on the contrary - it stops. It is convenient and allows the driver to not get distracted and do not write unnecessary moments with frequent stops;
• Cycled recording. No matter how big was not flash drive, its scope is limited. Therefore, DVRs can record video cyclically - erasing older files, replacing them with new ones. However, there is one small caveat. A large number of write-write cycles reduces the lifespan of a memory card;
• accelerometer or G-sensor. A very useful addition. The accelerometer responds to sudden changes in vehicle speed or position, such as during a stroke or maneuvering. A system is in these moments puts a special stamp on the file, which protects it from being deleted, for example, cyclic recording.

According to the structural characteristics

The design features when choosing registrars are no less important. The shape, the presence of additional cameras, fixed and more affects the usability of the device.

The size and shape

The sizes and shapes of registrars are not particularly standardized. Therefore, we can find a model of the most bizarre appearance. Here the choice is strictly individual. Highlight what is best and what is worse, objectively impossible.

Need a simple housing as a unit - have such a shape mirrors - and such exist. Even cylindrical, like IP cameras, are commercially available.

Number of cameras

There are some models, which can be connected to multiple cameras. For example, the rear-view or side on both sides of the vehicle, forming the overall picture with the final large angle. It is certainly convenient, but will have to pay extra.

According to sources of energy

Most often three different options to ensure supply: completely self-contained, and the combined power of the car. The most convenient of them - combined - when most of the time the recorder is powered from the mains car, and in unusual situations, such as when an accident is switched to battery power without interrupting recording.

The best models of inexpensive but good DVRs

Now that we know the theory, you can see that the market has to offer. We have selected some of the most interesting models. The main criterion was the low price of the device at maximum capabilities.

Dunobil Spiegel Duo

Quite an interesting model. First of all, because of the good combination of price and quality. Total for 3500 rubles user will receive a device with great potential. First of all, you can select FullHD resolution - 1920 × 1080. Recording can be performed cyclically, with no breaks. This may contribute to the existence and the accelerometer. Over the picture recorder is able to superimpose the current date and time. You can set the write protection and autostart.
