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.

Power connector

The type of connector used in the recorder to power it. First of all, you should pay attention to this item if you plan to change the registrar with ready-made wiring for one or another type of connector ( miniUSB, microUSB, USB-C, DC 12V). Thus, the replacement of the registrar rests simply on installing a new one without re-changing the cable.

Screen type

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 r...elatively “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.

Aperture

The aperture ratio of the lens installed in the video recorder.

This parameter determines how much the optics weaken the transmitted light flux. The aperture ratio is indicated by a fraction - for example, f/1.8. The smaller the number in the denominator, the more light the lens can transmit. A conventional model with an f/2.2 lens will theoretically produce a darker image than a recorder with a high-aperture optics of f/1.5.

High aperture ratio is important, first of all, when shooting in low ambient light conditions: it allows you to capture images in the twilight and dark hours of the day without creating additional artifacts in the form of noise. At the same time, when shooting with high-aperture optics, the blurring effect of moving objects in the frame is reduced. On the other hand, the actual quality of the recorder camera depends on many other factors - in particular, the type of matrix, the image processor used, etc. Therefore, the aperture ratio specified in the characteristics is not the ultimate truth - it is rather for reference.

Full HD (1080)

The maximum resolution and frame rate of video taken by the recorder in the Full HD (1080p) standard.

Many people associate the term Full HD with a resolution of 1920x1080 — and indeed, this resolution is very popular, including among DVRs. However, this standard also covers other options — in particular, 1440x1080 (4:3 aspect ratio) and 1920x540 (halved vertical size). In general, support for this resolution is a good indicator for a modern registrar, indicating that the device belongs to at least an average level.

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 low-cost Full HD recorders, shooting can be carried out at very low speeds — 15 fps or even 10 fps. 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.

Quad HD

The maximum resolution and frame rate of video recorded by the recorder in the Quad HD standard.

In terms of detail, the Quad HD standard sits between Super HD and Ultra HD. It does not have a specific standard resolution, but most often in video recorders there is shooting with a frame size of 2560x1440. However, even such models are relatively few; and more specific values like 2688x1440 are used even less often. There are also quite unusual options — for example, a square frame 1440x1440.

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 the case of Quad HD, a frequency of 24 fps or 30 fps is usually used, and the difference between these speeds is generally unimportant.

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.

IPS screen

This technology provides high-quality colour reproduction, high brightness and wide viewing angles, and thanks to the improvement and reduction in price, the price of IPS screens is constantly decreasing. At the same time, the meaning of the IPS screen may arise in the case of using a Dashcam at the scene of an accident in order to clarify the situation and review the footage. And the availability of an IPS screen indicates a device of a higher class.
