Glass mount

Glass mount provided in the model with the corresponding type of installation (see above).

Note that in many models, not the recorder itself is attached to the glass, but the bracket, on which, in turn, the device is installed. To learn how to fix the recorder on the bracket, see "Mounting the recorder". And the options for attaching to glass can be as follows:

Sucker. The traditional suction cup, which works due to the reduced pressure between the mount and the glass — as a result, the force of the pressure of the outside air and holds the structure in place. One of the main advantages of this option is “reusability”: the suction cup can be repeatedly stuck and detached at the request of the user, and after removal it leaves practically no traces. However this type of fastening is considered somewhat less reliable than stickers; however, the suction cups used in video recorders are usually of a special design that provides sufficient reliability for practical use. Therefore, this type of mount is extremely popular in modern registrars.

Sticker. A plate with a layer of special glue, due to which the entire structure is held on the glass. Such mounts are considered more reliable than suction cups, they are less prone to wear and do not lose effectiveness even with minor damage such as cracks and chips. On the other hand, the sticker is usually installed "once and for all..." and does not provide the ability to quickly remove the bracket. And although dismantling by itself is possible, however, it will not work to reuse the sticker, and the glass will most likely have to be cleaned from traces of glue. So installing a recorder with such a mount requires special care and attention.

Note that some models of DVRs are supplied immediately with both types of mounts described above in the kit. This allows the user to choose the option of their choice — including changing the suction cup to a sticker, if the need arises.

Dashcam mount

A method of fixing the recorder on a device that plays the role of a mount - a bracket for the windshield, a helmet platform, a clamp for the steering wheel or another similar structure.

Latch. One of the most popular options nowadays. The latch, along with the magnet (see below), refers to quick-release fasteners, allowing you to easily and quickly remove the device and return it to its place. This feature can be useful, for example, if the car is left overnight in an unguarded place, where an unremoved recorder can become a bait for thieves; In addition, the entire device sometimes has to be removed to view and copy footage. Specifically, latches are considered more reliable than magnets; they can be used even with the most massive devices, and are also cheaper to produce.

- Magnet. Another type of quick-release mount: a powerful permanent magnet that is strong enough to hold the recorder in place. This type of fastener is easier to use than a latch: to install it, just “stick” the device to the mount, and to remove it, just pull it hard. Another advantage is that the latch can be broken by unsuccessfully applying force, whereas in magnets there is practically nothing to break. On the other hand, this type of mount is less reliable: in the event of a shock or a powerful jerk, the force of attraction may not be enough. Therefore, although magnets ar...e widespread, they are still inferior in popularity to latches.

— Magnet/latch. An option that involves the presence of both types of mount in the kit - both a magnet and a latch. This allows you to choose an option at your discretion depending on the situation. For example, for quiet movement around the city and frequent stops during which you have to remove the recorder, a magnet is better suited, and a more reliable latch will be useful on a long journey, especially if the roads are of poor quality. At the same time, such versatility is not required so often, which is why this option has not become widespread.

- Screw. Fixation with a screw that is screwed into a socket on the recorder body. Connecting and disconnecting such a fastener takes noticeably longer than in the case of a latch or magnet, however, the reliability of fasteners of this type is very high - even a strong tug is more likely to tear off the suction cup or sticker that holds the entire structure than damage the screw mount.

— Fixed / non-removable. An option found exclusively in windshield recorders installed using a sticker (see “Attaching to glass”). The platform with the sticker in such models is rigidly fixed to the body; and in some models the role of such a platform is played by the upper side of the body, specially made flat. The advantages of fixed mounts are simplicity, compactness and high reliability. On the other hand, this installation method requires the recorder to be permanently on the glass and does not allow you to quickly remove it and put it back: removing the sticker is quite difficult, and it cannot be reused.

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.

Recording features

Among the photo and video functions used in the dashcam, we can distinguish G-sensor, rotating lens, live, HDR< /a>, WDR, polarizing filter, DEWARP and Time Lapse. More about them:

— G-sensor (video saving). A sensor that monitors shocks and vibrations acting on the DVR. The main function of this sensor is to ensure the safety of video materials in the event of an accident: in the event of a strong impact, characteristic of a collision or fall, the recorder with a G-sensor automatically saves the previously recorded video to a non-volatile memory protected from overwriting. Thus, materials about an emergency are not only guaranteed to be saved, but with a high probability remain intact even if the recorder itself is damaged. In addition, the G-sensor is used in parking mode — see "Functions" for details.

— Swivel lens. The ability to rotate the lens of the registrar horizontally or vertically, and in some cases — on both planes. This feature allows you to adjust the camera's field of view.

— Sound recording. Ability to record sound with a video recorder. First of all, we are talking about recording conversations in the cabin, which can become an add...itional argument in disputable situations — for example, they will allow you to determine whether the driver was talking on a mobile phone at the time of an accident, whether he noticed the situation on the road, how he assessed it, etc.

— Live broadcast. Allows you to remotely connect to the DVR and monitor what is happening from the camera in real time. It is very important if there is an additional camera in the cabin, when you can track the situation, for example, in taxi services, courier delivery, etc. This function will also become important and useful when a car is stolen, when you can not only see the hijacker from the video from the camera, but also track the route of his movement.

— HDR (high dynamic range). A function that increases the dynamic range of the recorder. Dynamic range is the maximum difference between the brightest and darkest area achievable within a single frame. Initially, this range for digital matrices is small, so an image with large brightness differences (for example, a road against a sunset sky) turns out to be either strongly overexposed in bright areas or very dim in dark areas. HDR addresses this shortcoming and also improves the overall colour quality. This is implemented as follows: the camera takes several frames with different settings and from them forms the finished image. At the same time, this technology is simpler and cheaper to implement than WDR, which is similar in purpose (see below). The main disadvantage of HDR is that this type of shooting increases the blurring of fast moving objects in the frame somewhat.

— WDR (Wide Dynamic Range). A function similar in purpose to HDR described above: it is used to improve the quality of a “picture” that has strong differences in brightness. The key difference between these technologies is that WDR works at the hardware level — due to high-end matrices. This allows you to achieve the required dynamic range within a single frame and do without gluing several frames — as a result, WDR, unlike HDR, does not give a blurring effect and does not worsen the detail of moving objects in the frame. The downside of this quality is the high price.

— Polarizing filter. The presence of a polarizing filter in the main camera of the DVR. Such a filter reduces the brightness of glare arising from strong light on glass, water and other similar surfaces. This greatly improves image quality, especially when shooting in sunny weather.

— DEWARP. A technology used to correct the "picture" obtained using a wide-angle lens. Such lenses are often used in DVRs; one of their drawbacks is their propensity for the fish-eye effect, the characteristic distortion when straight lines in the frame turn into rounded ones. The DEWARP function eliminates this shortcoming — it "bends back" curved lines, correcting the geometry of objects in the frame. Note that such a correction does not always work 100% accurately, however, the picture processed by DEWARP is anyway more reliable than without this technology.

— Time Lapse. A special mode of operation in which video recording is carried out at a slow frequency, which in practice is mainly used for shooting slow processes. Thus, for example, a long journey or a long sunset can fit into a 3-minute video.

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.

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.

Screen resolution

Resolution of the display installed in the recorder.

The higher the resolution (with the same diagonal) — the clearer the image is, but the more expensive the screen itself. At the same time, high resolutions are not needed to set the camera in the desired position and to work with the basic settings of the device. So you should pay attention to this parameter only if you plan to use additional functions that require a high-quality “picture” — for example, a GPS navigator (see “Functions”) or a remote camera that plays the role of a reversing camera.
