Year by year, the scope of registrars as such is noticeably expanding. Most often, devices of this kind can be seen in car interiors somewhere on the windshield or dashboard. Many users in the process of choosing such devices ask quite natural 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 and determine the best resolution for the DVR. We also designate a small list, which includes the most intelligent models, distinguished not only by their high-quality “stuffing”, but also by the matrix scan acceptable for most motorists.
Types of permits
Modern devices, as a rule, have Full HD-scan, that is, most models on store shelves are high-resolution DVRs. The higher this indicator (measured in pixels (px), the clearer the reproduced picture.
Types of development:
- SD - 720x576 px.
- HD - 1280x720 px.
- Full HD - 1920x1080 px.
- UHD – 3840x2160 px.
The latest resolution of the DVR can be called exotic, as it is extremely rare. Expensive models capable of performing full-scale shooting have such a sweep. The most popular among motorists are DVRs with Full HD-matrix. In terms of cost, they are not much ahead of conventional HD gadgets, so many users prefer to pay a little extra for picture quality.
Recording speed (FPS)
It is also worth noting separately that the second most important shooting parameter is the recording speed. It often happens that some unscrupulous manufacturers include the ability to record in high resolution in the specification for their device, but “forget” to specify the maximum readout speed with such a scan. As a result, it turns out that the user seems to have bought a Full HD DVR, 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, and Full 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 overpay for supposedly high resolution. Today, it makes no sense to buy gadgets with an SD scan: you will only see the general picture, and car numbers will be read in a ratio of about 1 to 4 (if the latter are clean and the weather is good).
Nextconsider specific devices with Full HD and HD-resolution matrix.
Intego VX-295
This is a compact and budget gadget, and even though its optics are 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 received a good 2.4-inch screen, support for memory cards up to 32 GB and, despite the abundance of plastic, it is well-assembled, unlike similar budget fraternity. Add here a functional, and most importantly, an understandable menu, more than an affordable price tag, and we get the best budget DVR.
Model benefits:
- quality output picture;
- intelligent assembly and design reliability;
- intuitive settings;
- price.
Flaws:
decoder digitizes the stream only in AVI format
Estimated cost is 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 you to additionally stabilize the image on uneven roads.
By the standards of the budget segment, the output picture is good - clear and saturated. Despite its undeniable advantages: video resolutionDVR in Full HD, compactness and cost, the gadget also has obvious disadvantages. This includes unimportant work at night: four LEDs for IR illumination do little to help in the dark.
In addition, the existing 200 mAh battery is depleted before our eyes, so the "tethered" mode will be enabled in 50% of cases. At the cost of compactness, the size of the screen also fell. The current resolution of the DVR is too much for a one and a half inch display. The latter is enough only 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 analogues have not only similar problems, but also a lot of other shortcomings, which this model does not have.
Pros of the gadget:
- more than affordable price tag;
- great high-res picture (during daylight hours);
- the presence of a G-sensor (accelerometer);
- small dimensions;
- cute and versatile appearance.
Cons:
- "raw" and slow software, like most budget devices;
- no support for the popular H.264 codec;
- mediocre microphone;
- model not suitable for night shooting.
Estimated price is about 1800 rubles.
KARKAM DUO
One of the hallmarks of this Full HD DVR is its 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 discreetly as possible somewhere.somewhere in the corners of the windshield, without attracting too much attention. Both cameras have good viewing angles of 140 degrees, which is quite acceptable for the Full HD resolution of the DVR.
The modularity of the design contributed to equipping the device with a more sensitive GPS receiver. The screen resolution of the DVR and a large display allow you to easily view 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 traffic police cameras and other "surprises" that the detector did not detect.
Features of the model
In addition to Full HD-resolution recording on the DVR, the model has another indisputable advantage - it is a capacious 1100 mAh battery. Therefore, there were no complaints about the battery life of the device.
Model benefits:
- fixing the video stream from two angles (two cameras);
- support for large memory cards up to 128 GB (SDXC);
- hidden cams;
- presence of a GPS module.
Flaws:
price is high if all you want is a DVR
Estimated cost is about 15,000 rubles.
TrendVision TDR-708GP
Against the background of other venerable representatives of the premium segment, 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 affordable for the segment.
The device received a wide-angle lens with very high-quality glass lenses, a well-proven Ambarella processor that quickly digitizes video in MP4 format, there is a lane tracking sensor, as well as all kinds of voice prompts that warn the driver about one or another danger.
The built-in 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. The built-in GPS-module allows you to work with maps and warns of stationary traffic police cameras ahead. The sensitivity is not as good as that of the same Karkam, but the module copes well with ordinary duties.
Distinctive features of the gadget
The model has a rechargeable battery as a fly in the ointment. A device worth 10,000 rubles implies an acceptable battery life, including, and in our case, a 300 mAh battery clearly does not cope with its task. At the maximum power consumption mode, the gadget lasts for 15 minutes, which is very short, especially when such a powerful processor as Ambarella is running on board. Therefore, many users have to get used to a small, but still cord, stretching from the registrar to the cigarette lighter or other power source.
Pros of the model:
- quality picture in high resolution;
- matrix works without noise and other "dirt";
- there is a duplication functionemergency protocol video;
- work with high-capacity memory cards (up to 128 GB);
- nice appearance;
- low price for the premium segment.
Cons:
battery with small capacity
Estimated price is about 10,000 rubles.
Summing up
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) using interpolation, that is, programmatically increase the resolution. This solution 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, even better, Full HD-scan, where everything that happens in front of the hood is well detailed, and the numbers are perfectly readable by automatics. Taking a device with a lower matrix resolution is simply impractical. You will get a blurry picture and unreadable license plates of the cars in front.
