Comparison SJCAM SJDASH vs Thinkware X350

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 f...or 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.

— 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 sign...s. 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.

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.

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.

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.

HDMI port is an output that allows you to use the recorder as an external player — namely, to broadcast video and audio from it to a TV, monitor or other video equipment that has the appropriate input. The HDMI standard is specially designed for high-definition content, it allows you to transfer even the highest quality video (up to and including UltraHD 4K); and inputs of this type are available in almost all video devices that support HD standards — in particular, in the vast majority of modern TVs. Note that a smaller version of the HDMI connector is usually installed in the recorder, and the appropriate cable is supplied in the kit, but the presence of the latter needs to be specified separately.

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.
