DJI Action 2 review: specs and price

The first number of the IP rating refers to protection against dust, while the second number refers to protection against liquid. E.g. a first number of 6 denotes that it is completely dustproof, and a second number of 7 denotes that the device can withstand full immersion in water.

You can operate the device easily, by pressing the screen with your fingers.

The device has a standard memory slot (such as an SD or micro SD card slot) that enables you to extend the built-in internal storage with affordable memory modules, or easily retrieve data, such as photographs, from the memory card.

With a dedicated bike mount you can attach the device to your handlebars, making it easier to see and to change the settings.

The device has an electronic display to present information to the user.

The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.

The device is dustproof and water-resistant. Water-resistant devices can resist the penetration of water, such as powerful water jets, but not being submerged into water.

An accelerometer is a sensor used to measure the linear acceleration of a device. A common application is detecting when a device changes between vertical and horizontal positions.

The internal storage refers to the built-in storage space available in a device for system data, apps, and user-generated data. With a large amount of internal storage, you can save more files and apps on your device.

It is compatible with a range of Android devices such as smartphones and tablets.

It is compatible with a range of iOS devices such as iPhones, iPads and the iPod Touch.

Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Newer versions provide faster data transfers.

A camera that supports live streaming can be used to broadcast video to certain platforms (such as Facebook, YouTube, etc.) via a first-party app.

Newer USB versions are faster and have better power management.

The USB Type-C features reversible plug orientation and cable direction.

A remote control allows you to control the device remotely. The remote control can be included or optional.

Devices with a HDMI or mini HDMI port can transfer high definition video and audio to a display.

GPS enables global positioning, useful in map, geo-tagging or navigation apps.

The device's battery life (when in use) as given by the manufacturer. With a longer battery life you have to charge the device less often.

Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. More battery power can be an indication of longer battery life.

The time it takes to fully charge the battery.

The battery is removable and can be replaced by the user if broken.

The battery can be recharged and used over again.

An indicator shows you when the device has low battery.

Fast charging technologies, like Qualcomm’s Quick Charge or MediaTek’s Pump Express, are used to reduce the time it takes to charge a device. For example, with Quick Charge 3.0, the battery can be charged to 50% in just 30 minutes.

More microphones result in better sound quality and enable the device to filter out background noise.

A stereo microphone allows to record audio files or movies in stereo without an external microphone.

A microphone port allows connecting external high-end or specialized microphones.

With a standard mini jack socket, you can use the device with most headphones.

The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.

Cameras with an adjustable FOV allow users to set view angles depending on their needs. A wider FOV captures a larger visible area, but with fewer details. A more narrow field of view captures less but in more detail and is often used for recording content at a distance.

Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.

The larger the sensor the more light the sensor captures yielding in better image quality.

With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.

A multi-lens camera captures two or more images and overlays them. This technology creates sharper images, especially in low light conditions, and allows you to use effects such as softening the background.

A BSI (backside illuminated) sensor is a camera image sensor which captures better quality images in poor lighting conditions, and offers better overall sharpness and image quality.

CMOS image sensors are slowly replacing CCD sensors, due to reduced power consumption and better image quality. They can be very compact and cost relatively little to produce.

The maximum resolution available for videos shot with the main camera. Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions.

Field of view (FOV) is the part of the world that a device can view and record. A wider field of view allows you to capture more of the action.

A timelapse shows a long passage of time sped up. A series of photographs taken from the same position over a long period is joined together to create a short video. It is great way to capture things like the setting sun, or clouds moving across the sky.

Slow-motion is an artistic video effect that makes time seem to go slower. It is achieved by recording a video at a higher frame-rate than the standard playback rate of 24fps or 30fps. Depending on camera capabilities, frame rates for slow-motion videos vary between 60fps and 960fps.

A phase-detection autofocus system is faster than a contrast detection autofocus system. Even when recording scenes with a lot of fast movements, the videos are sharp and clear.

When recording movies they stay focussed and sharp.

24p is a video format (24 frames per second) traditionally used in cinema. Nowadays, it is used to create film-like motion characteristics.

The higher the movie recording bitrate the better the movie quality with more and crispier details and less compression artifacts.

A raw image file contains minimally processed data from the image sensor. Raw files are so named because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor.
