What is the automatic shutdown of the driving recorder?

The first choice is whether there is a card! Many driving recorders may turn off automatically after a period of time without a card.

If it is loaded, confirm whether it is a high-speed card of C 10.

The above confirmation is to confirm whether the battery is recharged.

If all the above problems are eliminated, it will be sent back for repair if it is still the same.

Driving recorder is an instrument to record the images and sounds of vehicles during driving. After installing the driving recorder, it can record the video images and sounds of the whole driving process of the car and provide evidence for traffic accidents. People who like to go to road trip can also use it to record the process of conquering difficulties and obstacles. Recording the time, speed and position in the video while driving is equivalent to a "black box". It can also be used for family DV shooting fun or family monitoring. You can also do parking monitoring at ordinary times. Driving recorder is mainly divided into portable driving recorder and integrated DVD driving recorder.

1. Protect the legitimate rights and interests of drivers. Pedestrians crossing the road, cyclists and motorcycles may be blackmailed if they collide with them. Drivers can provide valid evidence for themselves if they have a driving recorder.

2. Play back the monitoring video record, so that the accident responsibility can be seen at a glance, and the traffic police can handle the accident quickly and accurately; It can not only quickly evacuate the scene to restore traffic, but also keep valid evidence at the time of the incident and create a safe and smooth traffic environment.

If every car is equipped with a driving recorder, drivers will not dare to drive illegally, and the accident rate will be greatly reduced. Vehicles involved in accidents will be photographed by the driving recorders of other vehicles, and the number of traffic accidents will be greatly reduced.

4. When trying road traffic accident cases, the court will be more accurate and evidence-based in sentencing and compensation, and also provide evidence for insurance companies' claims.

5. In the cases of professional touching porcelain and road robbery, the driving recorder will provide decisive evidence for solving the case: the scene of the accident and the criminal's appearance characteristics.

6. Friends who like going to road trip can also use it to record the process of conquering difficulties and obstacles. Recording the time, speed and position in the video while driving is equivalent to a "black box".

7. It can be used as a DV to shoot the fun of life at home, and can also be used as a home monitor. You can also do parking monitoring at ordinary times.

8. As journalists are not prophets, almost all the news about the falling of Russian meteorites are recorded by recorders.

Composition mode

Instrument panel camera

Different driving recorder products have different appearances, but their basic components are:

(1) host: including microprocessor, data memory, real-time clock, display, lens module, operation keys, printer, data communication interface and other equipment. If the host does not include a monitor and printer, it should have corresponding data display and printout interfaces.

(2) Vehicle speed sensor.

(3) Data analysis software.

(4) As an important part of night vision function, infrared camera is essential.

Correlation classification

According to the assembly effect

Instrument panel camera

Driving recorders are mainly divided into two categories: portable driving recorders and integrated DVD driving recorders. Among them, portable driving recorders are divided into rearview mirror driving recorders and data driving recorders, which have the characteristics of good concealment, convenient installation, disassembly and replacement, low cost and simple use. After that, the loader integrated DVD driving recorder is generally used for special vehicles, which are divided into front and rear. This kind of recorder is expensive to install and difficult to refit, but it can keep the beautiful environment in the car after installation. In addition, some luxury models have installed driving recorders at the factory.

By camera number

According to the number of on-board cameras, there are generally 2-way, 3-way and 4-way driving recorders. One of the five inputs can be connected with a reversing camera, and the other four inputs can be used for driving records and video recording.

According to appearance and function

According to vehicle types and functions, it can be divided into: high-definition driving recorder, mini driving recorder, night vision driving recorder, wide-angle driving recorder, dual-lens driving recorder, multi-function machine, glasses multi-function driving recorder and so on.

By screen size

1.5 inch, 2.0 inch, 2.4 inch, 2.5 inch, 3 inch, 3.5 inch, 4.3 inch, etc.

According to memory capacity

Generally, the driving recorder has no built-in memory, and it depends on the memory card to expand or move the digital hard disk. In case of Micro SD card expansion or SD card expansion, the capacity is 2G, 4G, 8G, 16G, 32G; in case of mobile digital hard disk, the capacity can be: 250G, 500G, 1000G, etc. It can meet users' greater video storage needs. The larger the memory, the higher the price of the driving recorder. Generally, it is necessary to decide how much memory to buy according to the video clarity of the driving recorder and the recording and storage of the camera. There are 720p and 1080p high-definition driving recorders, 4G 720 p can only record about 1 hour and video 1080p.

Frame stream rate by video resolution

The resolution and frame rate of video files are important indexes to measure the image quality of driving recorder. The driving recorder market is mainly divided into four types: ordinary HD, HD, full HD and ultra-clear. Hd has 720p@30FPS, 720p@60FPS, 1080p@30FPS, 1080p@60FPS, which is ultra-clear.

According to the shooting angle

There are several shooting angles, most of which are adjusted according to the camera angle: 120 degrees, 140 degrees, 150 degrees, 170 degrees, 100 degrees, 90 degrees, etc. Mainstream single-lens driving recorders are equipped with wide-angle lenses of 120 degrees or 140 degrees. It is difficult for a single lens to reach the wide angle of 170 degrees. Even if it reaches 170 degrees, the picture will be seriously deformed, which will affect the clarity of the picture.

By video pixel

According to the pixel division, there are four kinds of driving recorders: 300,000 pixels and 6.5438+0.3 million pixels, 2 million pixels and 5 million pixels. Some labels with 654.38+200,000 pixels refer to still photos, not video pixel values.

Main parameter

First, wide angle

Instrument panel camera

About the wide angle of driving recorder, car owners and friends can learn about it according to the propaganda methods of many businesses. The wider the wide angle, the wider the monitoring screen. At present, the wide angle of the widely publicized driving recorder on the market ranges from 90 degrees to 170 degrees. In fact, the wider the wide angle of the driving recorder, the wider the visual range, the better. The wider the wide angle of the recorder, the more obvious the deformation of the monitoring picture.

For a simple example, many car owners and friends will see a convex mirror in the parking lot or at a sharp turn to see the car in front of the curved lane. It can be understood that the wide angle of convex mirror is very large, close to 180 degrees or even greater, but the picture you see is seriously deformed.

In order to meet the needs of some car owners for a large monitoring angle, and at the same time ensure that the picture taken by the recorder will not be obviously deformed, it is generally realized by splicing the monitoring pictures of two cameras into a complete panoramic monitoring picture.

Second, infrared night vision lamp

Limited by the use environment, technology, cost and other factors, the night vision effect of driving recorder is generally poor, which is the status quo of the industry. The night driving recorder mainly uses external light sources such as street lamps and car headlights, and some recorders will be equipped with LED fill light or infrared LED fill light to supplement the light source for taking pictures of the machine. However, due to the reflection of these auxiliary lights by the front windshield, the absorption of infrared light by the thermal insulation film, the automobile circuit and other factors, the night vision effect has little to do with the existence of auxiliary lights. The night vision effect of driving recorder is not ideal, and these auxiliary measures can only improve the present situation. The night vision effect of driving recorder depends on the light source environment around the car, and the night vision effect depends on the quality of the lens used.

Third, the resolution

As a friend of the owner, if the video recorded by the driving recorder requires high definition, you can choose a product based on Anba scheme, and the video resolution can reach 1920* 1080P. As most car owners, the video picture size and definition are not so high, so you can choose the driving recorder based on the chorus scheme, and the video resolution can reach1280 * 720 p. Or choose a lower-end Puqing 640*480P solution product. Many fake high-definition video recorders that claim to be able to record 1080P are realized by interpolation, and most of them are cottage products, so regular manufacturers dare not do so. In order to realize 1080P picture, many products will sacrifice the frame rate of the picture. For example, 720P can reach 30 frames. After interpolation to 1080P, the frame rate will be reduced from 30 frames to 20 frames or 15 frames due to the hardware performance of the driving recorder. And most importantly, when you record video with an interpolation resolution of 1080P that exceeds its own performance, those fake products will get stuck or crash from time to time. In short, it is generally applicable to buy a truly high-resolution driving recorder, and the principle of getting what you pay for is still applicable.

Fourth, glass lenses.

The quality of the lens determines the quality, color, clarity and night vision effect of your picture. There are mainly two kinds of lenses: one is glass lens, which has high cost, stable performance, good transparency and good temperature difference resistance; The resin lens has low cost, no difference in transmittance in a short time, deformation and discoloration under high temperature exposure, and weak temperature difference resistance. Many cheap knockoffs claim to use glass lenses, but in fact, it is difficult for consumers to tell whether it is glass or resin.

In order to control the cost, general manufacturers will use all-glass lenses or mixed glass lenses and resin lenses. Of course, car owners and friends can't directly distinguish the lens material when purchasing the driving recorder. In this regard, it is best to choose some products with brands, credibility and quality assurance.

Five, the size of the screen

China people are generally used to beauty, so the driving recorder also pursues a big screen, and often claims to have a big screen. The problem is that the driving recorder is only used for video recording. What do you need such a big screen for? Do I have to watch the recorder drive forward when driving? The bigger the screen, the bigger the space it occupies and the bigger the line of sight it blocks. In fact, the screen of the recorder plays a role in monitoring whether the recorder works normally. When you really need to watch a video, you always take down the memory card and plug it into the computer to watch it. Therefore, the screen of the driving recorder has little effect, or even nothing. There are many driving recorders that borrow DVD screens or navigator screens.

Six, cycle video function

When the memory card is full, the driving recorder will automatically replace the earliest recorded video clip with the latest recorded video clip in chronological order, thus ensuring that the latest video clip can be completely saved. But here also involves a common problem-missing seconds. If many video recorders have poor performance, they will miss a few seconds between two video clips and cannot be saved. The reason is that the machine can't start recording the next video while saving the previous video. Only after the previous video is saved will the next video be recorded. This process will miss a few seconds and it will be impossible to record and save.

Although it only takes a few seconds, traffic accidents often happen within a few seconds. If the recorder just missed the few seconds of the accident, then the purchased driving recorder lost its original meaning. It is suggested that car owners choose some driving recorders with guaranteed quality and stable performance.

Seven, gravity sensing function

Gravity induction, also called collision induction, means that the recorder is integrated with the car body. In the normal video recording process, when the car body collides and vibrates, the recorder will latch the video, and it will not be automatically overwritten when the video is repeated, so the video evidence will be automatically kept safe. In addition, the driving recorder also has a manual locking function. When the owner has a premonition of what may happen in front of him, the video will be locked and saved in advance, and it will not be covered when the recorder takes pictures in cycles.

Eight. Motion detection function

During driving, the picture is in a dynamic process, and the driving recorder must record and monitor it. Only after stopping for a short time or a long time can motion detection play its important role. But for short-term parking, continuous recording and short-term standby are of little significance to the recorder and the owner. But the driving recorder has not generally entered the stage of long-term parking monitoring. Therefore, it is generally recommended that car owners can turn off the motion detection function, instead, the recorder will not be suddenly recorded or not recorded because of the motion detection function, so that everyone mistakenly thinks that there is something wrong with the machine.
