Classification of driving recorder
The driving recorder is mainly divided into two categories: portable driving recorder and rear loader integrated DVD driving recorder. Among them, the portable driving recorder is divided into rearview mirrors recorders and data driving recorders. Such recordsThe instrument has the characteristics of good concealment, convenient installation, disassembly replacement, low cost, simple use, and other characteristics. The rear loader all -in -one DVD driving recorder is generally dedicated to special cars, and it is divided into two types: front and rear installation.The recorder costs high and it is difficult to modify, but after installation, it can maintain the beauty of the environment in the car. In addition, some luxury models have been installed in the factory when they leave the factory.
According to the number of car cameras, there are generally 2, 3, 3, 4 and 8 driving recorders.5 Input one of them can reverse the use of the car camera, and the other four -way driving record video is used.
The models and functions can be classified as: HD driving recorder, mini driving recorder, night vision driving recorder, wide -angle driving recorder, dual -lens driving recorder, multi -functional all -in -one machine, glasses -type multi -function driving recorder, etc.
Generally, there is no built -in memory in the driving recorder, and it is necessary to expand or move digital hard disk by memory card.If the Micro SD card extension or SD card extension, 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 the larger video storage needs of users. According to the personal needs, the larger the memory recorder price, the higher the price of the driving recorder. Generally, the clearness of the recorder video and the records of the camera decide how much memory is suitable for purchase.The high -definition driving recorder has 720P and 1080P, and the 4G card record 720P video can only record about 1 hour. The space occupied by 1080P videos is nearly twice of 720P.
The resolution and frame flow rate of video files are an important indicator of the quality of the quality of the driving recorder. The market is mainly divided into four types: Puqing, HD, HD, and ultra -clear., 720p@60fps, 1080p@30fps, 1080p@60fps, Chaoqing has 1296p@30fps.
There are several types of shooting angles, most of which are adjusted from the perspective of the camera: 90 degrees, 100 degrees, 120 degrees, 140 degrees, 150 degrees, 170 degrees, etc.The mainstream single -lens driving recorder is equipped with a wide -angle lens of 120 degrees or 140 degrees.The single lens is basically less than 170 degrees wide angle, and even if it reaches 170 degrees, it will be severely deformed, which will affect the clearness of the picture.
According to the pixels, the driving recorder is: 3 million pixels, 1.3 million pixels, 2 million pixels, and 5 megapixels. Some label 12 million pixels refer to static photos, not video pixels.
Purchase of driving recorder
When buying, product parameters are required to analyze the shooting angle, video resolution, compression format, cache, whether the video can be manually closed, emergency video, no interference in other car electronics, whether to match the card, etc.
Most of the camera angles of the driving recorder are about 100 degrees. This angle can basically ensure that the lanes on both sides of the vehicle can be photographed.Of course, it is better to choose a large angle as much as possible for the owner, but it also costs more money as a price.
Generally speaking, when the video resolution is 1280*720, it can basically ensure that the front license plates taken by the shooting can be seen clearly, and the license plate of the side lane is relatively blurred.In addition, the light sensitivity of the CMOS chip of the recorder and the glass of the glass of the lens outside.It is directly related to the effect of its shooting at night.
Most of the driving recorder uses H.264 compression format. There is no good compression method not only to occupy a larger storage capacity, but also requires higher the speed of the memory card. Otherwise, it is easy to lose the frame.sex.720P resolution H.264 compressed 1 minute fragment size is about 60MB.For the owner, a reasonable selection of the recording interval and capacity can help timely evidence to obtain evidence in time. Generally speaking, it is advisable to choose 1 minute as the interval time.
Choose as much cache as possible to bring smoother videos and better memory card compatibility.
The night vision effect refers to the low -illumination performance of the product. The excellent product is not the kind of LED light and infrared lamp. No matter the strong light light, there are no two car headlights.A reflective light is formed on the front glass, and the driving recorder seriously affects the viewing clarity of the sight, which has no effect at all.Remember, the products with the light lamp are from the hand of the cottage manufacturers, just for the buyers who do not understand the truth about the gimmicks of the products that publicize the products.
If it cannot be closed, it is not conducive to the privacy in the car, and what to say is recorded, there may be a very embarrassing situation.The recorders produced by regular brands on the market have a mute function.
Based on the characteristics of the cyclic recording of the aforementioned driving recorder, if there is a video is important, but the video in the future will be shot, then the important video in the previous video will be automatically deleted.At this time, an emergency video design appears. If you have important images, you only need to press a key manually, which will be forced to save this video.Automatic emergency video is to use a gravity sensor. When monitoring the vehicle violent vibration, it will automatically protect this video. This video will not be deleted automatically. This function will be very useful when the vehicle collides.
In order to reduce cost design, cottage products do not take any shielding measures. Without strict testing, they will interfere with GPS navigation, remote control, radio, tire pressure meter, and driving computers. The impact is huge when the situation occurs.
Due to the huge video files recorded by the driving recorder, the high -definition video is as high as nearly 100M per minute, so it has harsh requirements for the speed of the memory card.Low -speed card -issuing calorie driving recorder will lead to crash.Domestic marketing flash stuck cards are mixed. The same card, high -quality chips can repeatedly write more than 100,000 times, and the inferior ones can only be about 2000 times.It is generally recommended to buy a card with a genuine Class6 or above.
To buy easy operation, intelligent driving recorder.
After receiving the driving recorder, you can try it under various conditions, test it, and use it to be more safe and safe to use.
