The resolution of the DVR. Choosing an Automobile DVR

From year to year, the scope of application of registrars as such is significantly expanding. Most often, devices such a plan can be seen in the salons of cars somewhere on the windshield or dashboard. Many users in the process of choosing such devices are asked quite natural questions: what is the resolution of the gadget, which one to choose and how this indicator affects the quality and clarity of the picture.

Let's try to understand this question in detail and determine the best resolution for the DVR. Also we will designate a small list, which includes the most sensible models that distinguished themselves not only with high-quality "stuffing", but also acceptable for most motorists to develop a matrix.

Types of permits

Modern devices have, as a rule, Full HD-development, that is, most models on the shelves of stores are DVRs with high resolution. The higher this value (measured in pixels (px), the sharper the reproduced picture.

Types of development:

• SD - 720x576 px.
• HD - 1280x720 px.
• Full HD - 1920x1080 px.
• UHD - 3840x2160 px.

The last resolution of the DVR can be called exotic, since it is extremely rare. Such a scan has expensive models capable of performing full-scale shooting. The most popular among motorists are DVRs with Full HD-matrix. At a cost, they are just a little ahead of the usual HD-gadgets, so many users prefer to pay a little for the quality of the picture.

Recording speed (FPS)

Also, it should be separately noted that the second most important parameter of shooting is the recording speed. Often it happens that some unscrupulous manufacturers include in the specification for their device the ability to record in high resolution, but "forget" to clarify the maximum read speed with such a sweep. In the end, it turns out that the user seems to have bought a DVR with Full HD, but the image quality at this resolution leaves much to be desired, because the picture is distorted and incomplete.

The optimal indicator for any format, and Full HD in particular, is the minimum mark of 30 FPS. If this parameter is lower, then it's better to take a full HD device, and not overpay for allegedly high resolution. Today, buying gadgets with SD-development does not make sense: you will see only the general picture, and the numbers of cars will be read in a ratio of approximately 1 to 4 (with the purity of the latter and good weather).

Next, consider specific devices with Full HD and HD-resolution matrix.

Intego VX-295

It is a compact and budget gadget, and even though its optics are made of plastic, the image quality pleased many users. The resolution of the DVR matrix is denoted as HD, but the low noise level and quality factory calibration approximates the DVR's capabilities to Full HD devices.

The gadget got a good 2.4-inch screen, support for memory cards up to 32 GB and, despite the abundance of plastic, competently assembled, unlike a similar budget fraternity. Add here a functional, and most importantly - a clear menu, more than a democratic price tag, and get the optimal budget DVR.

The advantages of the model:

• A quality picture at the output;
• Smart assembly and reliability of construction;
• Intuitive settings;
• price.

Disadvantages:

• The decoder digitizes the stream only in AVI format.

Estimated cost - about 2000 rubles.

Artway AV-338

This is a DVR with a resolution of 1920x1080 pixels, that is, Full HD. Other advantages of the gadget are its light weight and dimensions, which allows to further stabilize the image on uneven roads.

By the standards of the budget segment, the picture on the output is good - clear and saturated. Despite its undeniable advantages: the resolution of DVR video recording in Full HD, compactness and cost, the gadget has obvious drawbacks. This can be attributed to unimportant work at night: four LEDs for IR illumination help little in the dark.

In addition, the existing battery for 200 mAh is depleted literally in front of the eyes, so the "tethered" mode will be turned on in 50% of cases. The price of compactness fell and the size of the screen. The current resolution of the DVR is a bit too much for a 1.5-inch display. The last enough except for the correct positioning of the gadget and no more. Despite all the shortcomings, the device can be called an excellent budget option, because competing analogs have not only similar problems, but also a lot of other shortcomings, which this model does not have.

Pros of the gadget:

• More than a democratic price tag;
• Excellent picture in high resolution (in daylight);
• The presence of a G-sensor (accelerometer);
• Small dimensions;
• Cute and versatile appearance.

Minuses:

• "Raw" and braking software, like most budget devices;
• There is no support for the popular H.264 codec;
• A mediocre microphone;
• The model is not suitable for night shooting.

Approximate price is about 1800 rubles.

FACING DUO

One of the distinguishing features of this DVR with Full HD resolution is a modular design. That is, its main unit is located under the panel or in the glove compartment, and the compact recorders themselves are placed as secretly as possible somewhere in the corners of the windshield, without attracting unnecessary attention. Both cameras have good viewing angles of 140 degrees, which is quite acceptable for the Full HD resolution of the DVR.

Modular design contributed to equipping the device more sensitive GPS-receiver. The resolution of the DVR screen and the large display allow you to easily view the maps, which, incidentally, are regularly updated from the official resource of the manufacturer. That is, the gadget is able to warn the driver in advance about the presence of stationary DPS cameras and other "surprises" that the detector has not caught on.

Features of the model

In addition to the Full HD-resolution recording on the DVR, the model has another undeniable advantage: it's a capacious 1100 mAh battery. Therefore, there were no complaints about the autonomous operation of the device.

The advantages of the model:

• Fixing the video stream from two angles (two cameras);
• Support for memory cards up to 128 GB (SDXC);
• Hidden installation of cameras;
• Availability of GPS-module.

Disadvantages:

• The price is too high if you only need a DVR.

Estimated cost - about 15 000 rubles.

TrendVision TDR-708GP

Against the background of other venerable representatives of the premium segment of this model, it was difficult to stand out. Nevertheless, the gadget has all the necessary characteristics for a full-fledged work together with a price tag that is democratic for the segment.

The device received a wide-angle lens with very high-quality lenses from glass, the well-proven Ambarella processor, fast-digitizing video in MP4 format, there is a lane-tracking sensor, as well as all sorts of voice prompts warning the driver of a particular danger.

The internal memory of the gadget is not so much - only 2 GB, but it is possible to expand it with memory cards up to 128 GB (SDXC) and forget about daily cleaning. Built-in GPS-module allows you to work with cards and warns about ahead standing stationary DPS cameras. The sensitivity is not as good as that of the same "Karkam", but with ordinary duties the module is doing well.

Distinctive features of the gadget

As a spoon of tar in the model is a rechargeable battery. The device costing 10,000 rubles implies an acceptable battery life, including, in our case, a 300 mAh battery with its task is obviously not working. At maximum power consumption mode, the gadget lasts 15 minutes, which is very small, especially when a powerful processor such as Ambarella is running onboard. Therefore, many users have to get used to a small, but still a cord, stretching from the recorder to the cigarette lighter or other power source.

Pros of the model:

• High-quality picture in high resolution;
• The matrix works without noise and other "dirt";
• There is a function of duplicating video on emergency protocols;
• Work with memory cards of increased capacity (up to 128 GB);
• Nice appearance;
• Low price for the premium segment.

Minuses:

• Rechargeable battery with a small capacity.

Approximate price is about 10 000 rubles.

Summarizing

The resolution of the DVR is one of the main characteristics, which directly depends on the quality of the existing matrix. Do not believe the seller's assurances that, for example, a gadget with SD or HD scanning can be "overclocked" to the next level (HD / Full HD, respectively) by interpolation, that is, by software increase the resolution. This decision only worsens the quality of the image, because it simply expands the image, and does not detail it. Therefore, it is better to take gadgets that fully support the format you need.

The most optimal option is HD or, even better, a Full HD scan, where everything that happens before the hood is well detailed, and the numbers are perfectly readable by the automatics. Taking a device with a smaller matrix resolution is simply impractical. You will get a blurry picture and unreadable numbers of cars ahead of you.
