When purchasing a recorder, you should not place an order simply by looking at the sales volume and the gimmicks promoted by merchants. You should consider more hardware configuration and brand factors. It is better to shop around and select more products for comprehensive comparison. Pay attention to the following four aspects when shopping:
1. First of all, the stability of the DASH CAM is mainly judged by its endurance. As long as the tachograph has strong endurance, the shooting will be very stable in general.
2. The pixel problem of the DASH CAM is also worth paying attention to. The average tachograph has more than 2 million pixels. When you buy a DASH CAM, you must take 2 million pixels as the standard. If the pixel is not reached, the image will be unclear and discontinuous. It is meaningless to buy such a tachograph.
3. If the shooting angle of the tachograph is not enough, there will be dead angles, which will affect the recording. The best camera angle is 140 degrees or 160 degrees. Generally, 100 degrees or more is enough.
4. The night effect of the DASH CAM is also very important. Night is a period of high incidence of accidents. At this time, it is very important to check whether the night camera of the DASH CAM is clear and whether it has the backlight prevention function. You must pay attention when shopping.
