Comparison HP F330s vs HP F510

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.

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 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.

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 °.

— 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 signs. 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.

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.

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.

AV output is an analogue output used to broadcast captured audio and video to an external display such as a TV. In registrars, such an output usually has the form of a mini-Jack connector, and a special cable is required for connection (often supplied in the kit, but there are exceptions). This interface does not allow working with HD resolutions, however, it does not require powerful hardware and can be provided even in the simplest and most inexpensive devices. Another advantage is that AV inputs (usually called composite) are found not only in modern, but also in frankly outdated video equipment like CRT TVs.
