The function of the dash camera

From the appearance style, the purchase direction of the driving recorder is roughly determined. Let's briefly talk about the functions of most driving recorders on the market. This part is mainly divided into two aspects of the hardware and software of the driving recorder to introduce.

Hardware function

The hardware of the driving recorder is mainly composed of a lens, a screen, a speaker, a microphone, an indicator light, a function button, and a power cord.


The most important part of the many components is the lens. The quality of the lens will directly affect the image clarity, wide-angle size, video image file size and other qualities.

Wide angle

In theory, the wider the wide angle of the dash cam, the wider the scene captured. However, as the wide-angle angle of the driving recorder becomes larger, the distortion of the shooting picture becomes more serious. Basically, all the dash cams currently on the market have a certain degree of distortion, but the situation is different from one to another. Generally, a wide-angle size of about 140° is sufficient.

Video resolution and pixel count

In many cases, whether the video records provided by car owners are clear enough is a key factor in whether the records can be used as evidence. Regarding the image quality of the driving recorder, in fact, it is mainly the resolution of the lens. The most common driving recorder is 1080P. The shooting effect is already very high, enough to use, you don't have to deliberately pursue high resolution or even high pixels. The number of pixels corresponding to the 1080P image is exactly 2.1 million (1920 × 1080 = 2.07 million, plus some wasted at the edge of the sensor). No matter how many pixels there are, the sharpness increase is not obvious, but because the average brightness of each pixel decreases, the night vision effect becomes worse. Focus on overall performance, not be confused by the size of the numbers. In addition, how to distinguish whether the lens is of good quality? Just look at the frame rate of the product. Basically, it needs to reach a rate of 29 frames (FPS) to ensure better definition.


There are usually three types of F-values ​​of the dash cam's aperture: F1.8, F2.0 and F2.2 respectively. The calculation method of the F-value is: F-value = lens focal length / lens aperture diameter, so the number behind F-value The smaller it is, the larger the aperture diameter of the lens is. Among the several aperture F values ​​mentioned above, the aperture of F1.8 is the largest.

The biggest advantage of a large aperture is that it allows us to shoot bright images even in dark scenes (such as night scenes). In the case of the same exposure time, the larger the aperture of the lens, the greater the amount of light that enters, and the brighter the picture will be.

When the external light is brighter, there is often no need to enter too much light. In this case, it is easier to shoot images with appropriate contrast and higher definition by using a small aperture. In addition, when other parameters remain unchanged, a small aperture can also increase the depth of field, reduce the degree of background blur, and make it easier to make objects with different distances appear clearly together.

Therefore, for driving recorder products, it is obviously unreliable to blindly pursue a large aperture, and more attention should be paid to the performance of the photosensitive element, the adjustment of parameters and the software algorithm. In other words, as long as the photosensitive element of the driving recorder is powerful, well-tuned, and the software algorithm is accurate and efficient, even if a small aperture is used, it can still shoot good (or even better) images.


Because the rearview mirror and cloud mirror need to replace the original rearview mirror of the car in the installation position and fixing method, in terms of the screen, in addition to the size of the screen, it also needs to have anti-glare and multi-layer coatings. Better user experience.

Microphone and speaker

The microphone on the driving recorder generally has two purposes: one is used to record audio in the video, and the other is mostly used for voice control. Therefore, the microphone may need to cooperate with the software to ensure the filtering of environmental noise and the elimination of echo.

Due to the noisy environment such as wind noise and tire noise during the driving of the car, chats between people in the car, and music or broadcasting played by the car machine, the speakers in the driving recorder basically become a tasteless. Generally, only two kinds of driving recorders with software interactive, such as cloud mirror and light car machine, will use speakers to return execution results or perform related audio playback. There will be another better method for this kind of audio output.


The sensors are the most basic competitiveness for the current driving recorders on the market. The general approach is to use gravity sensors and gyroscopes to determine whether an accident has occurred in accordance with the magnitude of the vehicle body vibration, so as to automatically record and save the video before and after the accident, and the accident video will not be automatically overwritten by default. The light sensor can automatically adjust the screen display according to the brightness of the light, and the acceleration sensor can cooperate with the GPS module to complete a series of calculations and ADAS functions.

Types of dash camera

There are many brands of driving recorders on the market with different functional positioning. According to the appearance and function type, it is roughly divided into 4 categories and 5 categories:

Light vehicle machine type: In fact, it is similar to the floating central control screen of the current automobile manufacturers, and the function is basically similar to the cloud mirror, and the difference is mainly reflected in the fixed method. The purchase cost is basically the same as the cloud mirror.

Hidden: The most compact driving recorder, so it is also very concealed after installation. Of course, precisely because of its exquisite size, this type of driving recorder is generally not equipped with a display screen, so there will be no software integration in the equipment system, and there will rarely be third-party firmware modules to support it. The purchase cost is high and low.

Mini portable: The volume is between the hidden type and the rear-view mirror type, and it has a small display screen that can be used to display and play back surveillance video. It is usually fixed with suction cups or 3M glue during installation. There will also be expansion of hardware modules such as GPS, GPRS, and tire pressure monitoring.

Recommended video for you

Rearview mirror type: the largest volume of the driving recorder, the general direct fixing method is directly stuck on the original rearview mirror of the car, depending on the situation, increase the strap to fix it. The imaging range of the original rear-view mirror can be increased, and the rear-view mirror can be replaced with a display screen at the same time. But the disadvantage is that if you want to use the display, it will reduce the usability of the original rearview mirror. Most manufacturers will also add practical hardware modules such as GPS, GPRS, and tire pressure monitoring to increase the availability of the equipment. The purchase cost is generally higher than the hidden and mini-portable.

Rear-view mirror-type cloud mirror: Integrate the system based on Android into the rear-view mirror-type driving recorder to install more third-party software to achieve the effect of a driving tablet computer. It also has the same rich expandability as the rear-view mirror driving recorder, and the purchase cost is generally the highest of the four recorders.

Is it worth buying a dash cam?

The simplest way to answer the question of whether dash cams are worth it, is yes. For a relatively small investment, a dash cam has the potential to prove your innocence in the event of an accent, or capture crucial evidence like a number plate of another vehicle that could lead to a conviction.

Does dash cam reduce insurance?

All leading motor insurers are now accepting dash cam footage as evidence to be used in the event of a claim, some insurers even offer annual discounts of up to 20% to drivers who use a dash cam.

Are dash cams legal?

New South Wales: The Surveillance Devices Act 2007 means that you can record vision freely using a dashcam, as long as you have not installed it into a vehicle or premises that is not your own.

What should I look for in a 2021 dash cam?

Make sure the camera you're buying is at least 1080p, but higher resolution options are available if you want crisper video for noting finer details like driver faces. Night vision is a good feature to look for too, especially if you plan to use the dash cam for security when your vehicle is parked.

To sum up

Presumably you already have a certain understanding of the driving recorder. If you have any questions about this, please leave a message and discuss it together. It should be noted that the driving recorder is only a recording device, it does not have the role of preventing accidents. Moreover, there is no driving recorder that can effectively record the situation on both sides of the car with the current methods, so I still hope that friends drive civilly and pay attention to safety.
