How to choose the car video recorder In the process of buying a driving recorder, we will encounter some more difficult problems. Is not the higher the choice of pixels the better products? My driving recorder does not display, it easy to use? And what brand of driving recorder is better? Some key point to Pick out and buy car video recorder: 1080P or 1296P? 1080P almost become the standard now, then the need to choose a higher video output? This is a small knowledge, for example, 1080P images corresponding to the number of pixels just 2.07 million. How to calculate it? 1080P that is 1920 × 1080, is equal to 2.07 million. If the pixel is higher than 1080P, the pixel data is higher than 2.07 million, assuming that 1080P machine and 1296P machine are using the same memory card, not only reduce the video time, and increase the frequency of read and write card , resulting in the life of the memory card becomes shorter. Pixels higher than 1080P, clarity rise is not very obvious, but the amount of light entering to each pixel is reduced, will cause night vision effect worse, so 1080P is enough. A good product Just ask to see the license plate clearly？ In the case of relatively static, even the 720P drive recorder can clearly see the front of the license plate. Relatively static state, with the actual situation there is a certain gap. Can you see the license plate clear affected by the following factors: relative speed, relative distance, road roughness, lighting conditions, shooting angle and so on. General recorder for the front 3 meters, the relatively static object shooting is clearly. But if there is in motion, no matter how good the recorder is likely to shoot unclearly.
