Night vision effect Driving at night is more complicated than during the day, bumps and bumps are prone to occur when driving, and most of the porcelain bumps happen at night.

Some driving recorders have really poor shooting results at night, so be careful when you buy them. The user can select the same screen for video recording under the conditions of sufficient light and dim light, and then make a comparison and confirm. Power interface driving recorders generally have both built-in power supply and external power supply. The built-in power supply is generally a lithium battery, and a small number of them use AA batteries. During driving, most of the driving recorder is powered by a cigarette lighter. Therefore, the requirements for the built-in power supply do not need to be too high. Volume size Most domestic driving recorders stay in the integrated design of the camera and the display screen, and most of their installation uses a bracket to stick to the front windshield glass. If its screen size is too large, it will increase the size of the driving recorder and it is not convenient to fix it near the rearview mirror. In addition, the small size of the driving recorder is conducive to concealed installation, which can reduce the risk of smashing windows and being stolen. The price of the dash cam is 200 yuan for the cheap, and 2,000 yuan for the expensive. Within the range of 1,000 yuan, a price gap of 200 yuan is enough to improve product quality to a higher level, while product differences beyond 1,000 yuan are more in high-end features, such as the addition of safety warning, GPS navigation and other functions. Therefore, for a general driving recorder, choose a product with a price of 400 to 800 yuan, and its quality, performance and function are sufficient.
