What are the points to pay attention to when buying a driving recorder

Filming angle

Many driving recorders on the market will advertise themselves, with a wide-angle view of 120 degrees, even exaggerated to 140 degrees, 270 degrees, and claim that the picture will not be distorted, but in actual operation, the standard driving recorder with a wide angle of 120 degrees Often only about 105 degrees can be taken, and the shooting picture has already appeared more prominent bends. This is a common problem in wide-angle shooting, and it is purely flickering that it is said to be never deformed. From this point of view, let alone the wide angle of 140 degrees and 270 degrees. In addition, the blurring of the shooting due to the bending of the shooting screen also has the opportunity to prevent your driving record from becoming a legal weapon.

At this stage, it is possible to solve the problem of picture bending due to insufficient angle or excessive wide-angle, which is to take pictures of driving roads by means of dual-lens and dual-video.

Night vision

There are not a few Porcelain gangs dispatched at night, so the performance of the driving recorder at night is naturally very important, but most of the driving recorders on the market lack light supplementation equipment, and they can only “mute the fire” when driving at night. Some have LED light supplement function, but the light supplement ability is limited

Excessive noise during driving at night will eventually make the finished video product rough and lose the value of driving video.

The low shooting definition of some driving recorders also seriously affects the effect of night shooting, and the resolution is insufficient. This side reflects that the parameters of the camera’s CMOS and CCD are too low, and the shooting effect will naturally drop by a level.

For night vision, the most popular solution on the market is to use infrared supplement light, but the infrared supplement light is insufficient, and the limited light supplement ability will also cause the picture to be rough. Therefore, a camera with better light supplement ability is good for driving records. The purchase of the instrument has a high reference value. The recorder adopts multi-point infrared supplement light. Although it is not that more LED lights represent strong light supplement ability, the multi-point supplement light of the driving recorder can ensure the light of the supplement light. Evenly distributed to each angle, the fill light effect will be more powerful in dim situations.

Size

Most domestic driving recorders are still in the integrated design of the camera and the display. In fact, in Japan, South Korea, Europe and the United States, such driving recorders have been expressly prohibited, because when driving, too many electronic products in the front of the car are very difficult. It is easy to form a driving blind zone and generate new driving hazards.

In order to solve this problem, many foreign driving recorders have begun to abandon this complicated and space-consuming design and switch to a hidden installation design, which can eliminate hidden driving hazards and maintain the original car style in the driving recorder compartment. , Make the carriage more uniform and beautiful.

In addition, the small size has the advantage that it can effectively prevent the theft in the car. The property visible in the car is generally the target of the thieves. The small size is not easy to attract the attention of the thieves and is more conducive to theft prevention.

Gravity sensor

Gravity sensing means that when the vehicle speed changes suddenly, the driving recorder can immediately record the driving video 10 seconds before the speed change and 20 seconds after the sudden change, so that the incident before and after the occurrence can be fully recorded.

Many copycat driving recorders on the market are only a rough integration of the camera and the card reader, but do not have the ability to capture photos by gravity sensing. This is a serious flaw. Driving recorders that usually ignore this function can easily cause seconds and pauses in the shooting picture.

Therefore, it is necessary to choose a driving recorder with gravity sensing function. The driving recorders produced by genuine manufacturers basically have this function, but the amplitude of real-time recording is usually only 15 seconds before and after the sudden change in speed, and the driving record of half a minute is still There is a chance to miss key records.

other

In addition to the above points that need to be paid attention to when purchasing, try to choose products with large caches. Large caches can bring users smoother videos and better memory card compatibility. It will automatically record when driving, turn off automatically, and automatically cover. These are the basic functions of the driving recorder, so remember to ask clearly when you buy it.
