Comparison Gazer F118 vs Gazer F117

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.

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.

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.

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.

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 advanced...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.
