Comparison Aspiring Reflex 7 vs Aspiring Reflex 5

The sensor is a key element of any digital camera; it is from it and from signal processing technologies that the quality of the resulting image primarily depends. In this case, the type refers rather to the brand or brand of the matrix; it is usually indicated if the recorder is equipped with a high-quality sensor that is noticeably superior to most solutions on the market.

One of the most popular such options is Sony. The specific characteristics of the matrices ( IMX179, IMX222, IMX291, IMX307, IMX317, IMX322, IMX323, IMX326, IMX335, IMX415) may vary, but anyway, such a sensor is a sign of a high-end DVR.

In addition, there are models equipped with matrices from other manufacturers — Aptina, OmniVision, Samsung(GalaxyCore), Sandvik. Such solutions are generally considered to be simpler and more democratic than Sony — both in terms of price and functionality. Nevertheless, Samsung has a lot of developments...in the field of electronics, and even such relatively “simple” sensors are usually more advanced and of higher quality than “know-names”.

Another manufacturer that produces fairly high-quality matrices is Panasonic. Such sensors are not as widespread as those described above, but they are still found in video recorders, including pretty advanced.

Model of the processor used in the dashcam

The term "video chip" is used mainly for devices with classic capabilities, "processor" — for advanced models with an abundance of non-standard functions. However, anyway, we are talking about the same component — the main computing unit, the characteristics of which directly affect the capabilities of the recorder as a whole. Knowing the model of the processor, you can find detailed data on it and evaluate how satisfied you are with a device based on such electronics. Of the most advanced modern chips, one can name, in particular, Ambarella A7L, Ambarella A12, Novatek NTK96655, Novatek NTK96660 and HiSilicon Hi3516.

The maximum video resolution supported by the optional DVR camera. Depending on the design and configuration, we can talk about both a remote camera and a camera for filming the interior (see above for both); this nuance should be clarified separately.

The higher the resolution, the more detailed the image from the camera will be, the more small details will be normally visible on it. On the other hand, high detailing affects the volume of materials to be filmed and the requirements for the “hardware” of the registrar (and, accordingly, affects the cost).

In general, additional cameras of modern recorders can be divided into the following categories:

— SD. "Standard" resolution (as opposed to HD — "high resolution"). A rather modest frame size, which at the same time allows you to significantly save memory for video recording and is suitable even for low-cost recorders. Specific resolution options include, but are not limited to, 628x582, 640x480, and 720x480.

— HD 720p. The traditional, most popular resolution for this video recording standard is 1280x720. In addition to it, registrars also found 960x720 (aspect ratio 4:3) and reduced in height 1280x480. HD is the most modest of today's high-definition standards, but still provides pretty decent detail.

— Full HD 1080p. The "classic of the genre" for this standard is the resolution of 1920x1080, however, there are other values in registrars, including very speci...fic ones — such as 1440x1080 (4:3 aspect ratio) and 1920x540 (halved vertical resolution). This is a fairly solid indicator even for the main camera of the registrar, and there is no need to talk about additional ones.

— Super HD. Not a particularly popular standard in video technology, which, nevertheless, has found application in video recorders. Most often provides a resolution of 2304x1296, which provides even more

Maximum video frame rate supported by the optional DVR camera. Depending on the design and configuration, we can talk about both a remote camera and a camera for filming the interior (see above for both); this nuance should be clarified separately. Anyway, it is with this frequency that the shooting is carried out by default.

The higher the frame rate, the clearer the moving objects will be on the video, the less they will be blurred and the less “jerky” the video itself will be. It is believed that the most comfortable for the human eye is a speed of 24 to 60 frames per second; a lower frequency is already perceived as a “slideshow”, and a higher one only increases the amount of material being shot, without giving a visible increase in quality. At the same time, registrar cameras can also provide higher filming speeds than 60 fps — this provides good visibility of individual moving parts in slow motion or frame-by-frame playback.

Touch screen similar to those used in smartphones and tablets. Control by touching the icons on such a display often turns out to be more convenient and intuitive than through the classic buttons, and sometimes it is simply irreplaceable — for example, it is very convenient to mark points on the map with a touch when using a GPS navigator (see "Functions"). On the other hand, such screens are more expensive than usual ones, and it makes sense to use them mainly in advanced registrars with an abundance of additional features.

Note that there are other specific types of control in registrars — voice control and gesture control. They are not as functional as touch ones, but they are noticeably safer when used while driving; see "Functions" for details.

Availability of a backup power source in the device design. Such a source comes into operation when the main power supply from the on-board vehicle network is unavailable, to finalize the recording when the ignition is turned off, during an accident and in other situations (for example, if you need to view the captured videos on the DVR).

— Battery. The battery “under the hood” of recorders most often has a low capacity, sufficient for several minutes of autonomous operation. As a rule, this is a lithium-ion or lithium-polymer battery, which is an additional guarantee in case of emergency situations. First of all, the battery can be useful in case of an accident: if the voltage in the cigarette lighter socket disappears due to damage, the recorder will still remain operational and will be able to record at least a few more minutes after the accident.

— Supercapacitor (ionister). A special energy drive is an ultra-high-capacity capacitor. Such a drive has a number of advantages over a battery. In particular, supercapacitors are immune to low and high temperatures, sunlight, they do not lose capacity as they wear out, and do not catch fire or explode even in extreme situations. And even in the event of a strong impact (for example, in the event of an accident), such a power source is more likely to remain operational than a battery. Ionisters are rightfully considered a much more ad...vanced and reliable backup power option. True, the capacity of such a capacitor is only enough to save the last recorded video and turn it off correctly - it does not allow the device to function autonomously even for several minutes. However, in the traditional use of DVRs, in general, no more is required, so in such cases, the practical advantages of this type of backup power significantly outweigh the disadvantages.
