Year by year the scope of application of recorders asthose expanding markedly. Most often, such a device can be seen in the car somewhere on the windshield or dashboard. Many users in the process of choosing such devices are asked quite legitimate questions: what is the resolution of the gadget, what to choose and how this indicator affects the quality and clarity of the picture.
Let's try to understand this issue in detail anddetermine the best resolution for the dvr. We will also designate a small list, which includes the most intelligent models, distinguished themselves not only with high-quality "stuffing", but also with an unfolding matrix acceptable for most motorists.
Types of permissions
Modern devices have, as a rule, FullHD development, that is, most of the models on the shelves of stores are DVRs with high resolution. The higher this indicator (measured in pixels (px), the clearer the reproduced image.
Types of scan:
- SD - 720x576 px.
- HD - 1280x720 px.
- Full HD - 1920x1080 px.
- UHD - 3840x2160 px.
The last resolution of the DVR can becalled exotic, as it is extremely rare. Such a sweep have expensive models capable of performing full-scale shooting. The most popular among motorists are DVRs with Full HD-matrix. At cost, they do not overtake the usual HD gadgets at all, so many users prefer to pay a little extra for picture quality.
Write speed (FPS)
Также отдельно стоит отметить, что вторым по The importance of the shooting parameter is the write speed. It often happens that some unscrupulous manufacturers include in the specification for their device the ability to record in high resolution, but “forget” to specify the maximum read speed during such a sweep. The result is 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 jerky and incomplete.
The best indicator for any format, andFull HD in particular is the minimum mark of 30 FPS. If this parameter is lower, then it is better to take a full-fledged HD device, and not to overpay for supposedly high resolution. Today, it does not make sense to buy gadgets with SD development: you will only see the general picture, and the numbers of the cars will be read in a ratio of about 1 to 4 (with the latter clean and in good weather).
Next, we consider specific devices with Full HD and HD-resolution matrix.
Intego VX-295
Это компактный и бюджетный гаджет, и даже Despite the fact that its optics is made of plastic, the image quality has pleased many users. The resolution of the matrix of the DVR is designated as HD, but the low noise level and high-quality factory calibration bring the recorder's capabilities closer to Full HD devices.
The gadget got a nice 2.4 inch screen,support for memory cards up to 32 GB and, despite the abundance of plastic, correctly assembled, in contrast to the similar budget fraternity. Add here a functional, and most importantly - clear menu, a more than affordable price tag, and get the best budget DVR.
The advantages of the model:
- high-quality picture on the output;
- sensible assembly and reliability of the design;
- intuitive settings;
- price.
Disadvantages:
- The decoder digitizes the stream in AVI format only.

Artway AV-338
This is a DVR with a resolution of 1920x1080 pixels, that is, Full HD. Other advantages of the gadget are its small weight and dimensions, which allows to additionally stabilize the image on uneven roads.
По меркам бюджетного сегмента, картинка на выходе it turns out good - clear and rich. Despite its undeniable advantages: the resolution of the video recorder of the DVR in Full HD, compactness and cost, the gadget has obvious disadvantages. This may include unimportant work at night: four LEDs for IR illumination do not help much at night.
In addition, the existing battery is200 mAh is literally depleted before our eyes, so the “on a leash” mode will be enabled 50% of the time. At the cost of compactness fell and the size of the screen. The current resolution of the DVR is a bit too much for a half-inch display. The latter is 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 counterparts 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 (during daylight hours);
- 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;
- mediocre microphone;
- The model is not suitable for night shooting.
Approximate price - about 1800 rubles.
CARD DUO
One of the distinguishing features of thisFull HD video recorder is a modular design. That is, its main unit is under the panel or in the glove compartment, while the compact recorders themselves are placed as covertly as possible somewhere in the corners of the windshield, without attracting too much attention to themselves. Both cameras have good viewing angles of 140 degrees, which is quite acceptable for Full HD resolution of the DVR.
Modular design contributedequipping the device with a more sensitive GPS receiver. The screen resolution of the DVR and the large display allow you to easily view the maps, which, by the way, are regularly updated from the manufacturer’s official resource. 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 detected.
Features of the model
In addition to Full HD-resolution recording onDVR, the model has another indisputable advantage - it is a capacious rechargeable battery at 1100 mAh. Therefore, no complaints about the autonomous operation of the device were noted.
The advantages of the model:
- fixing the video stream from two angles (two cameras);
- support for large memory cards up to 128 GB (SDXC);
- hidden installation of cameras;
- availability of GPS module.
Disadvantages:
- The price is too high if you need only a DVR.
Estimated cost - about 15 000 rubles.
TrendVision TDR-708GP
Against the background of other venerable representativesThe premium segment of this model was difficult to stand out. Nevertheless, the gadget has all the necessary characteristics for full-fledged work, along with a price tag that is democratic for the segment.
The device received a wide-angle lens with a veryhigh-quality glass lenses, the well-proven Ambarella processor, smartly digitizing video in MP4 format, has a lane tracking sensor, as well as all sorts of voice prompts warning the driver about a particular hazard.
The gadget has not so much built-in memory - only2 GB, but it is possible to expand it with memory cards up to 128 GB (SDXC) and forget about the daily cleaning. Built-in GPS-module allows you to work with maps and warns of standing in front of the stationary cameras DPS. The sensitivity is not as good as that of the same Karkam, but the module copes with ordinary duties well.
Distinctive features of the gadget
As a fly in the spoon modelaccumulator battery. A device worth 10,000 rubles implies an acceptable battery life, including, but in our case, a 300 mAh battery obviously does not cope with its task. At the maximum power consumption mode of the gadget, it takes 15 minutes, which is very little, especially when such a powerful processor as Ambarella is working on board. Therefore, many users have to get used to even a shallow, but still 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 video backup for 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 - about 10 000 rubles.
Summarizing
DVR resolution is one ofmain characteristics, which directly depends on the quality of the available matrix. Do not believe the seller’s assurances that, for example, a gadget with SD or HD development can be “overclocked” to the next level (HD / Full HD, respectively) using interpolation, that is, by software, increasing the resolution. Such a decision only worsens the quality of the picture, 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 best option is HD or what elsebetter, Full HD-scan, where everything that happens before the hood is well detailed, and the rooms are perfectly readable by automation. Taking a device with a lower resolution matrix is simply impractical. You will get a blurred picture and unreadable numbers of the cars ahead.
