Comparison SilverStone F1 Hybrid Mini vs AdvoCam FD One

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.

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.

This feature means that the power to the DVR (usually from the cigarette lighter) is supplied directly through the mount on which it is installed, and not through a separate cable. The mount itself is usually made quick-release.

Actually, the power cable in such models is also available — however, it is connected to the mount, and not to the registrar itself. Thanks to this, such a wire can be easily fixed in a strictly defined position; however, even without special fixation, he does not particularly move from his place. This feature provides a number of advantages over the more traditional connection format. Firstly, the wire does not hang around the cabin and does not create inconvenience. Secondly, it does not need to be searched for and reconnected every time when installing the recorder — just install the device on the mount. The latter is especially convenient if the recorder needs to be removed and put back often — for example, if the car has to be regularly left in an unguarded parking lot, where there is a risk of theft from the passenger compartment.

The cable is usually connected to the mount using a connector with the ability to quickly connect and disconnect — in case the wire needs to be removed from the passenger compartment without removing the mount. At the same time, many models use a standard connector like miniUSB or microUSB, which allows you to use a third-party power cable if necessary (for exam...ple, if the standard cable is lost or damaged). However, for a full guarantee, such details do not hurt to clarify separately.

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 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.

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.

The viewing angle provided by the main camera of the DVR. As a rule, it is indicated along the diagonal of the frame, less often - horizontally, because of this, models with the same numbers in the characteristics may differ somewhat in the actual field of view. So if you have doubts about this, when choosing, it does not hurt to find and watch video samples from different models.

Other things being equal, a wider viewing angle allows you to cover more space, but individual details in the frame are smaller. In addition, wide-angle lenses give geometric distortions of the image (however, DEWARP can be provided to eliminate them, see "Functions"). As for specific figures, viewing angles up to 120° inclusive are considered relatively small for modern registrars, values of 121 - 140 ° can be called average, 141 - 160 ° are above average, and the most wide-angle models are able to cover a space of more than 160 °.

— Speed on video. The ability to display data on the current speed of the car on the video being shot - usually in the form of numbers in one of the corners of the frame. As a rule, the device receives speed information from the built-in GPS sensor (see below). This function can be especially useful when analyzing ambiguous situations - for example, as additional evidence that the driver did not violate the speed limit.

— GPS module. Built-in GPS satellite navigation module, which allows you to determine the current coordinates of the device. The specific ways in which this information can be used may vary depending on the other functionality of the registrar. Thus, it is data from GPS that is used to display speed on video (see above), as well as for the operation of the GPS informer and GPS navigator described below. There are other options, sometimes quite original - for example, if you have a 3G/4G modem, a beacon mode may be provided ( GPS tracker - see below).

— GPS informant. A function that provides the driver with various useful information related to the current location. As the name suggests, the location itself is determined using GPS. One of the most popular ways to use an informant is to warn of approaching traffic cameras, stationary post...s and speed control systems that are not detected by a traditional radar detector. In addition, other similar functions may be provided - for example, a message about an area with a high accident rate or a separate large hole on the road. To operate the GPS informer, a database of relevant objects is entered into the device’s memory; When purchasing, it doesn’t hurt to clarify what exactly this database contains, how fresh it is, and whether it allows for updating and manually adding points.

— GPS navigator. The device can operate as a full-fledged GPS navigator. For this, in addition to the GPS module itself, the design provides built-in maps, as well as a fairly large display to display them. This allows you to do without purchasing and using a separate navigator, but this function is not particularly popular in modern DVRs. Firstly, it significantly affects the cost of the device; secondly, a regular smartphone or tablet with GPS is often enough to navigate on public roads; thirdly, recorders most often have rather modest navigation capabilities and are often inferior even to smartphones/tablets, not to mention specialized devices.

— GPS tracker. Another function found in recorders with a GPS module (see above). A GPS tracker allows the device to operate in beacon mode, constantly transmitting data about the location of the car to one or another recipient - for example, taxi service dispatchers, the customer of cargo transportation, etc. Such beacons are also sold as separate devices, but it is easier (and sometimes cheaper) to buy and install a recorder with this function. In any case, it is worth considering that a 3G/4G modem is usually used to transfer data (see below) - so to use the tracker you will have to buy a SIM card and regularly pay for mobile communications.

— GLONASS. The device supports the GLONASS navigation system, the Russian analogue of the GPS described above. Most often, this function is provided in addition to the GPS module: simultaneous use of two systems improves the speed and accuracy of positioning, and also provides an additional guarantee in case of failures in one of them.

—Galileo. European satellite navigation system, created as an alternative to American GPS. Note that it is under the control of civilian departments, not the military. With a full fleet of 24 active satellites, the system provides an accuracy of up to 1 m in public mode and up to 20 cm with the GHA service. Working in conjunction with GPS, Galileo provides more accurate position measurements, especially in densely populated areas.

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.
