Processor

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.

HD (720)

The maximum resolution and frame rate of video recorded by the recorder in the HD (720p) standard.

The classic resolution for this standard is 1280x720, but there are other options in DVRs — in particular, 1280x960 (4:3 aspect ratio). Anyway, HD is not outstanding, but quite a decent indicator that allows you to get a video with good detail (for example, it is usually quite possible to make out numbers on cars in close proximity to a car on it).

As for the frame rate, the higher it is, the smoother and less blurry the video will be, the better the details on moving objects will be visible, and also the more space the footage will take up. It is worth noting here that in some inexpensive models, shooting in HD at very low speeds — 15 – 20 fps is used to reduce the cost. Such a shooting speed allows you to watch video more or less normally, but for a normal display of moving objects, a higher frame rate is still desirable — at least 25 frames / sec. It is also worth saying that, in general, for a comfortable perception by a person, a speed of 24 to 60 frames per second is considered quite sufficient, however, among the registrars there are models that can shoot HD at 120 fps. The meaning of this speed is to ensure that individual details on moving objects are as clearly visible as possible in slow motion or frame-by-frame viewing.

Super HD

The maximum resolution and frame rate of video taken by the recorder in the Super HD standard.

Super HD is a rather specific standard that exceeds Full HD in resolution, but falls short of Quad HD. The traditional frame size for this format is 2304x1296, but there are models with a lower horizontal resolution — 1728x1296. Anyway, Super HD is quite popular among DVRs: it provides good detail and does not require particularly powerful hardware.

As for the frame rate, the higher it is, the smoother and less blurry the video will be, the better the details on moving objects will be visible, and also the more space the footage will take up. However, in Super HD models this figure usually ranges from 25 to 30 fps, and this difference is hardly fundamental.

ADAS features

LDWS (lane control). A system that monitors the car's position within the lane: it monitors the car's position on the road and, if it deviates from the current lane, gives a warning signal, attracting the driver's attention. This signal can literally save the lives of road users if the driver is distracted or falls asleep at the wheel. DVRs with LDWS will be especially useful for those who have to spend a lot of time driving without a break. However, if road markings are of poor quality or absent, this function becomes useless.

FCWS(distance control). A system that monitors the distance to the car in front and gives a signal if this distance is critically reduced and a collision is possible. Typically, FCWS is activated at a certain speed (for example, 40 km/h and above), and its sensitivity can be adjusted to suit traffic density. A collision warning is usually displayed and accompanied by an audible signal.

LLWS(headlights reminder). A sensor that monitors the level of ambient light; When the light level decreases, LLWS reminds the driver to turn on the headlights. Such a reminder may be useful not only in the dark, but also during the day - for example, in cloudy weather or when entering a tunnel.

Sign recognition. Intelligent system for automatic recognition and analysis of road signs. Typically..., this function aims to recognize speed limit signs and provide advance warning to the driver to adhere to the prescribed speed limits. However, many recorders with a similar function perfectly “see” other road signs, duplicating them to the driver on the screen of the head unit as a kind of safety net.

- Antison. A feature that reduces the risk of falling asleep while driving. When the Antisleep mode is turned on, the recorder, as a rule, periodically plays a special sound signal; in some models this sound stops itself, in others the driver must manually turn off the signal, confirming that he is not sleeping. However, it is worth keeping in mind that even the most advanced Antison system does not provide a complete guarantee against falling asleep while driving. Therefore, the most correct behavior when you are very tired is to stop and rest; This function should be used only in extreme cases.

External camera

One or more remote cameras in the standard equipment of the registrar, used for video recording of the traffic situation behind the car. In the vast majority of cases, the remote camera is attached to the DVR in one copy. It covers the rear "stern" of the car and is simultaneously used as an assistant when reversing parking — the picture from the camera can be displayed on the DVR screen in real time. There can be several remote cameras, which provides a wider coverage of the DVR's field of view.

Video resolution

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

Frame frequency

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.

Angle of view

The angle of view of the additional camera of the DVR. 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. And the viewing angle can be indicated both horizontally and diagonally, which is why models with the same numbers in the characteristics may differ somewhat in the actual field of view. However, in this case, this difference is not critical.

In theory, a wider field of view allows you to cover more space, but individual details in the frame are smaller. In addition, wide-angle lenses give geometric distortion at the edges of the picture; and the DEWARP technology (see "Features") used to eliminate them is not usually used in additional cameras.

Screen size

The diagonal of the display installed in the DVR.

A large display, on the one hand, provides additional convenience, on the other hand, it affects the dimensions and price of the entire device. Therefore, manufacturers choose a diagonal in such a way that the device can be used normally and at the same time it is not too expensive and bulky. So, for a classic registrar that does not have additional functions, a small display is enough — 2 – 2.5", 1.5 – 2", or even less : it completely allows you to manage the settings and control what exactly gets into the frame, and to fully view the footage, you still need a computer, TV or other large screen. A size of 2.5 – 3 " by the standards of such devices can already be called average, and screens of 3" or more are typical mainly for fairly advanced models, often with an abundance of additional functions.

Also note that there are models that do not have a display at all. To control the operation parameters and check the position of the frame, such a recorder is connected to an external device — for example, to a smartphone via Wi-Fi.
