What brand of lens is good for driving recorder?

camera lens

First of all, the driving recorder belongs to camera products, focusing on the lens. Everyone has a misunderstanding. It's not the pixels that determine the quality of a shot. Why is12 million SLR camera more expensive than16 million pixel card machine? Mainly the lens, the workmanship and quality of the lens are directly related to the driving recorder. Driving recorder is a photographic equipment, and now the highest definition player only supports 6544. But how to judge the camera of driving recorder? There are two ways here in Bian Xiao.

1: Maximum aperture. The real value of the maximum aperture is that the surveillance camera can increase the amount of light in low light, thus achieving the best exposure combination. You can judge by looking at the diameter of the camera with the naked eye. This is a high-end lens, compared with ordinary lenses! Let's have a look.

2. The transparency of the lens depends on a little feeling. A good lens looks bright and hateful, while a bad lens looks less transparent, as can be seen from the above picture.

I tell you, the difference is an open secret. A 30W pixel can be different from 1200W pixel, but it has become a big selling point in the eyes of merchants. Extended promotional pixels are the "basic unit" of image quality. In fact, pixels are only one unit used to calculate digital images. Like photographic photos, digital images have continuous shadows. If we enlarge the image several times, we will find that these continuous tones are actually. This smallest graphic unit can usually display a coloring point on the screen. The higher the pixel, the richer the sample and the more realistic the color is. This is equivalent to a high-resolution TV screen, but the clarity of the picture inside depends on the clarity of the display screen. However, the bigger the brand, the less likely it is to have false pixels, so I believe that big brands, such as DOD, PAPAGO, Ruiying and Tiezong, generally do not increase false pixels.

plan

The scheme is also one of the important factors that determine the quality of a driving recorder. Now the common schemes of driving recorder are: Anba, Yong Lian, SQ, full-time, etc! This scheme is like the operating system of a computer. A good operating system can not only maximize the hardware, but also support better hardware. At present, the best solution is Anba, and high-end driving recorder brands such as Ruiying /dod/mobile/MIO mainly use Anba. The main features of Anba are supporting 5 megapixel lens 1920* 1080p HD, H.264 with a maximum of 60 frames per second, no second leakage and stability. The second is Yong Lian, which has high cost performance and also supports 1080p. The stability decoding is not as good as that of Anba!

wide-angle

Driving recorder is different from ordinary camera, which needs to record the image in front of the vehicle. When the vehicle passes by, many driving recorders can't shoot it! At present, the wide angle of driving recorder is 70,90, 120, 140 degrees. At present, the biggest single lens is Ruiying ry 980/ Ling Du DM900! ? Shenzhen 170-degree wide angle, 360-degree panorama can be achieved by splicing two lenses, such as Ruiying RY940. The wider the wide angle, the fewer blind spots. But now businesses basically do false propaganda and exaggerate the wide angle. So how should we distinguish the size of wide angle? It's simple. You can look directly at the curvature of the lens. Here we still use a wide-angle lens to compare with the ordinary driving recorder. See figure 1.

Driving recorder is different from other image products, because it needs multiple copies, so it can use wide-angle technology. Can the publicity from the perspective of merchants be credible? As unreliable as a pixel. There are many brands of driving recorders at present. Most of them are small companies and brands, and their sense of responsibility is not great. Competition in the industry urges them to exaggerate publicity, and real publicity will inevitably not be recognized by customers. Therefore, the wide angle of driving recorder is often exaggerated. Today, I will teach you to really recognize the wide angle of the driving recorder in your hand.
