The importance of driving recorder, What should we focus on when choosing car black box

The driving recorder is an instrument that records related information such as images and sounds while the vehicle is driving. After the driving recorder is installed, it can record the video images and sounds of the entire driving process, which can provide evidence for traffic accidents. People who like to drive by themselves can also use it to record the process of conquering difficult obstacles. While driving, you can record while walking, and at the same time record the time, speed, and location in the video, which is quite a “black box”. It can also be used as a DV shooting fun at home, or as a home surveillance. Usually you can also do parking monitoring, install a driving recorder, video data can not be cropped, if cropped, can not provide help after a liability accident occurs. It is also to prevent those unavoidable injury feigning behaviors in today’s society.

So let me tell you how to choose the driving recorder?

Classification of driving recorder

Installation Method

The driving recorder is mainly divided into two categories: portable driving recorder and integrated DVD driving recorder. The portable driving recorder is divided into rearview mirror driving recorder and data driving recorder. The instrument has the characteristics of good concealment, convenient installation, detachable replacement, low cost, simple use, etc., and the integrated DVD driving recorder of the rear loading machine is generally dedicated to the special car, and is divided into two kinds of front loading and rear loading. The cost of the recorder is high and the modification is difficult, but it can maintain the beautiful appearance of the interior of the car after installation. In addition, some luxury models have already installed a driving recorder when they leave the factory.

Lens of Cameras

According to the lens of car cameras, there are generally two, three, four and eight lens recorders. One of the five lens inputs can be connected to a reversing camera, and the other four lens inputs are used for driving records.


According to the model and function, it can be classified into: high-definition driving recorder, mini driving recorder, night vision driving recorder, wide-angle driving recorder, dual-lens driving recorder, multifunctional all-in-one, glasses-type multifunctional driving recorder, etc.

Screen Size

1.5 inch, 2.0 inch, 2.4 inch, 2.7 inch, 2.5 inch, 3 inch, 3.5 inch, 4.3 inch, 4.7 inch, 5 inch, 7 inch, 10 inch, 12 inch and no screen, etc.

Memory Capacity

Generally, the driving recorder does not have built-in memory, so it is necessary to expand the memory card or move the digital hard disk. If it is Micro SD card expansion or SD card expansion, the capacity is 2G, 4G, 8G, 16G, 32G; if it is a mobile digital hard disk, the capacity can be: 250G, 500G, 1000G, etc. It can meet users’ larger video storage requirements. According to personal configuration, the larger the memory, the higher the price of the driving recorder. Of course, the resolution of the driving recorder’s video and the storage of the camera’s recording will determine the appropriate amount of memory. , High-definition driving recorder has 720p and 1080p, 4G card recording 720p video can only record about 1 hour, 1080p video occupies nearly twice the space of 720p.

Video Resolution

The resolution and frame rate of video files are an important indicator of the quality of the driving recorder. The driving recorder market is divided into four types: HD, HD, Full HD, and Ultra HD. The HD driving recorder has 720p @ 30FPS. , 720p @ 60FPS, 1080p @ 30FPS, 1080p @ 60FPS, there is 1296P @ 30FPS in Super Clear.

Camera Angle

There are several general shooting angles, most of which are adjusted according to the camera angle: 90 degrees, 100 degrees, 120 degrees, 140 degrees, 150 degrees, 170 degrees, and so on. The mainstream single-lens driving recorder is equipped with a 120-degree or 140-degree wide-angle lens. A single lens basically cannot reach a wide angle of 170 degrees, and even if it reaches 170 degrees, the picture will be seriously deformed, which will affect the clarity of the picture.

Video pixel

According to the division of pixels, there are four types of driving recorders: 300,000 pixels, 1.3 million pixels, 2 million pixels, and 5 million pixels. Some 12 million pixels indicate static photography, not video pixel values.


Selection of driving recorder

When purchasing, you need to analyze the product parameters, the camera angle, video resolution, compression format, cache, whether the video can be manually closed, G-sensor, does not interfere with other automotive electronics, whether it is equipped with a card and so on.

Camera angle

The camera angle of the driving recorder is mostly around 100 degrees. This angle can basically ensure that the lanes on both sides of the vehicle are photographed. Of course, it is better for the owner to choose the largest camera angle, but this also costs more money.

Video resolution

Generally speaking, when the video resolution is 1280 * 720, it can basically ensure that the license plates of the front shots can be clearly seen, while the license plates on the side lanes are relatively blurred. In addition, the sensitivity of the CMOS chip of the recorder and the quality of the glass on the outside lens. It is directly related to the effect of its night shooting.

Compression format

The driving recorder mostly uses the H.264 compression format. Without a good compression method, it not only means that it takes up more storage capacity, but also requires higher speed of the memory card, otherwise it is easy to drop frames and affect the compatibility of the memory card driving recorder Sex. 720P resolution H.264 compressed 1 minute clip size is about 60MB. For car owners, a reasonable choice of recording interval and capacity helps to obtain evidence in the event of an accident. In general, it is appropriate to choose 1 minute as the interval.


Choosing as large a cache as possible will result in smoother videos and better memory card compatibility.

Night vision effect

The night vision effect here refers to the low-light performance of the product. The outstanding products are not the ones with LED lights and infrared lights. No matter how strong the fill light is, no two car headlights are on. Reflections are formed on the front glass, and the driving recorder seriously affects the clarity of the video of the line of sight, and has no effect at all. Keep in mind that the products with fill light are from the manufacturers of the cottage, just for the gimmicks of many hype-promoting products that do not understand the truth.

Turn on recording

If it can’t be closed, it is not conducive to the privacy of the car, and if something is said to be recorded, there may be an awkward situation. Recorders produced by regular brands on the market have a one-button mute function.

Emergency recording

Based on the characteristics of the cyclic recording of the driving recorder, if there is an image that is important, but the next video is still to be shot, then the previous important video will be automatically deleted. At this time, the design of emergency recording appeared. If there is an important image, just press a key manually, it will be forced to save this video will not be automatically deleted when the card is full. Automatic emergency recording is the use of a gravity sensor, which will automatically protect this video from being automatically overwritten and deleted when a violent vibration in the vehicle is monitored. This function will be very useful when a vehicle collides.

Shielding measures

Cottage products are designed to reduce costs without taking any shielding measures. Without strict testing, they will interfere with automotive electronics such as GPS navigation, remote controls, radios, tire pressure gauges, and trip computers. The impact will be huge when conditions arise.

Whether with card

Because the video files recorded by the driving recorder are very huge, high-definition videos can reach nearly one hundred megabits per minute, so there are strict requirements on the writing speed of the memory card. A low-calorie heat recorder can cause crashes. Domestic commercial flash memory cards are mixed, with the same card, high-quality chips can be rewritten more than 100,000 times, and low-quality ones can only be used about 2,000 times. Buyers are generally advised to match the original genuine CLASS 10 card.


To buy an easy-to-operate, intelligent driving recorder.


After receiving the driving recorder, you can try it under various conditions. After the test is completed, it will be more safe and reliable to use.
