— Diagonal. The larger the screen, the more convenient it is to watch (and also to control if the display is touch-sensitive). On the other hand, the diagonal of the
built-in display directly affects the size of the case, and action cameras should be quite compact. Thus, there are practically no screens larger than 2.5" in modern action cameras.
— Resolution. Theoretically, the higher the resolution, the clearer and better image the screen produces. On the other hand, displays in action cameras are designed mainly for menu operation and footage preview — and for these purposes, especially high resolutions are not needed. For models with two screens, the rear display is considered the main display.
— Touch screen. Display equipped with a sensor and responsive to touch like in smartphones/tablets. Control through such a display is simpler and more intuitive than using buttons, rotary knobs, etc. On the other hand, for more or less convenient control, the
touch screen must be quite large, which affects the dimensions of the entire camera.
— Front screen. The presence in the camera of a screen mounted on the front panel, next to the lens. Other displays may not be present at all; in such cases, the diagonal, resolution and other parameters are given for
the front screen.
It is worth noting that most often the simplest black
...-and-white displays are installed on the front panel, suitable only for text and basic graphic information. However, even on such a screen, you can display a wide variety of service data: the current mode of operation (photo, video, standby), the resolution used, the shooting time, the amount of free space on the drive, etc. But more advanced displays are not used as front displays: a full-colour screen is needed only for taking a selfie, and for this you can use a remote display with a remote control(see "Control") or a smartphone connected to the camera.—
Protective case. A special container that provides additional protection against dust, moisture, shock, extreme temperatures and other similar “troubles”. The specific degree of protection in each case must be specified separately. In order not to interfere with the shooting, the box is made of transparent materials. In addition, we note that some cameras can only be mounted on mounts in a protective case (or in a mounting frame — see below), since the camera body may not have mounts for this.
—
Curved mount(helmet). A mount designed to mount the camera on a helmet or other curved surface. The design of such a mount is based on a curved platform with an adhesive layer or hook-and-loop, the shape of which approximately corresponds to the shape of the surface of the helmet. Such a fixture can provide a more secure hold than the classic flat platform (see below).
—
Flat mount. One of the basic and simplest mounts used to fix an action camera on almost any uniform surface: snowboard, skateboard, car hood, etc. It is a small flat platform, on one side of which the camera is attached, while the other is fixed on the desired surface (using hook-and-loop, special glue, etc.). Note that flat mounts are often used for mounting on a helmet. However, there is a separate type of mount for this, with a curved platform (see above).
—
3-axis mount. It differs from other types of mounting in the presence of three movable nodes that allow you to rotate the camera at an angle of up to 90 degrees in three axes. This allows you to choose the most interesting or successful shooting angle — on the side of the helmet, for example. Such options are usually compatible with many other mounts, so they can be used in conjunction with a handlebar, curved mount, etc.
—
Bicycle/moto handlebar. Mount for installing the camera on a small pipe, such as the handlebars of a bicycle or motorcycle. Usually, it looks like a clamp, and the size of the fastening can be adjusted within a fairly wide range, adjusting it to pipes of different diameters.
—
Suction cup(on glass). Camera mount, fixed in the right place with a suction cup. Allows you to install the device on flat and slightly curved surfaces. At the same time, note that such fasteners are not held as securely as flat or curved ones (see the relevant paragraphs). On the other hand, the suction cup is easy to attach and remove and leaves no marks. Therefore, mounts of this type are mainly used for installation on car glass when the camera works as a DVR.
—
Clamp (clip). The clip-pin mount is quite versatile since it allows you to hang the camera on almost any suitable piece of equipment (backpack strap, unloading belt, belt, etc.). But at the same time, it is not very suitable for extreme shooting due to the relatively low reliability.
—
Head mount. A device for fixing the camera on the head — usually on the forehead, like a headlamp. In addition to being hands-free, this placement has another advantage: the camera lens faces the same direction as the user. In this case, the mount itself is usually a system of elastic straps and is designed to be worn directly on the head, in contrast to the curved platform for the helmet. However, in some models, the possibility of putting on a helmet is also allowed.
—
Chest mount. This mount is a system of elastic straps that allows you to fix the camera on the user's chest, shooting a little lower than the "eyeball". Like the head mount (see above), it easily adapts to the desired size.
—
Mounting frame. A device designed to mount the camera on various mounts — helmet-mounted, on the handlebar, etc. The camera body itself often does not have mounts for such fixing, which is why you have to use additional equipment. Note that a similar function is often performed by a protective case(see above); the mounting frame, in contrast, provides almost no protection. However, in the frame, the camera body remains as open as possible. This provides additional features — in particular, it allows you to connect various cables and effectively use the built-in microphone, which is not possible with many protective cases.
—
Monopod(selfie stick). It is a rod, usually folding, and sometimes adjustable in length; on one end of the rod is a mount for the camera and on the other — a handle for holding in your hand. By the name, such a monopod is intended mainly for filming itself — thanks to the length of the rod, the camera can be held at a convenient distance for this. However, other applications are also possible: for example, with the help of a monopod, you can “look” quite far over the edge of a cliff or around a corner. The main disadvantage of such a device is that one hand is constantly busy.
In addition to those mentioned above, other types of mounts may be included in the delivery package — for example, for musical instruments (for a guitar neck, a drum kit bar, etc.), for a surfboard, etc.
Action camera control. Specified only if this model is equipped with an optional external control device. So in this case we are talking more about the type of remote control.
The remote control itself is convenient, first of all, because reaching directly to the camera can be inconvenient, and sometimes even dangerous. But the types of devices used for this can be as follows:
—
Portable remote control. Traditional external control panels that do not have displays. Theoretically, the functionality of such a remote control can be different, but only the most basic functions are usually available — start/stop recording and taking photos; the rest of the possibilities can be controlled traditionally. Such remotes often have a strap for attaching to a hand or a mount for installing such a strap. The absence of a screen, on the one hand, makes them as simple, reliable and autonomous as possible, on the other hand, it limits the functionality.
—
Remote screen with remote control. Remote controls complete with their displays. Like simpler devices, without a display, they are usually designed to be mounted on the hand. Therefore, the built-in screens have a very small diagonal — otherwise, it would be simply inconvenient to wear them. Nevertheless, even such a screen turns out to be quite functional and useful. It usually plays the role of an external viewfinder, allowing you
...to see what exactly the camera is recording at the moment — an important feature, given that the action camera's screen (if any) is most often not visible to the user at the time of shooting. Of course, various service information can also be displayed on the remote display.
It is worth noting that many modern action cameras can use a smartphone connected via Wi-Fi as an external display. However, a specialized remote screen is often more convenient due to its compactness, security and convenient attachment to the arm.The largest memory card capacity supported by the camera model.
This limitation is due to two points. First, the larger the drive, the more computing power is required to use it. Secondly, each type of memory card has its maximum capacity. For example, the capacity of an SD HC card cannot exceed 32 GB, larger drives already belong to the SD XC standard, and if it is not supported, the maximum card capacity cannot exceed 32 GB.
It is strongly not recommended to exceed the maximum allowable capacity: even if the card is recognized by the device, its normal operation is not guaranteed.
The model name of the proprietary battery used in the camera. Knowing this name, you can easily find a spare or replacement battery for the device.
