About the car rear view camera
With the booming of the economy, more and more people buy cars for convenience for their life. And for safety life, the drivers often want to install the rear camera for their cars. So here is the problem we meet: how to choose the rear view camera for our cars? What should we care about the details of car rear view camera?
The rear view camera of the car has been widely used in various vehicles. How to choose a good rear view camera? For the customer, it may be very difficult, because the products on the market are uneven, each has its own statement, but no matter how, you can check the performance of the camera from the following aspects:
1. Chip
(Because this is the core chip of the rear view camera of the car, so it is very important. From the chip: there are CCD and CMOS chips, CCD stands for manufacturers: SHARP, SONY CMOS stands for manufacturers: OV, PIXEL, Micron Different chips, the price is different)
CCD and CMOS chips are an important part of the rear view camera of the car. They can be divided into CCD and CMOS according to different components. CMOS is mainly used in products with lower image quality. Its advantage is that manufacturing cost and power consumption are lower than CCD. The disadvantage is that CMOS camera has higher requirements on light source; CCD is a high-end technical component used in photography and video. A video capture card is included. CCD and CMOS are very different in technology and performance. Generally speaking, the CCD effect is better, but the price is also more expensive. It is recommended to select the CCD camera without considering the cost.
2. Sharpness
Sharpness is one of the important indicators for measuring cameras. In general, the quality of the image with high definition will be better. The TV line is divided into: CCD is 420 TV line, CMOS is 380 TV line. For now, the product with clarity of 420 line has become a reversing camera. The mainstream products, 380 lines can also be selected if the debugging is good. However, according to the chip level of each camera, the difference of the photosensitive elements, including the level of the debugging technician, the quality effect of the products of the same level of the same chip may be different. On the contrary, the night vision effect of the high definition product will be played. Some discounts.
Night vision
The night vision effect is related to the clarity of the product. The higher the resolution, the night vision effect of the product will not be very good. This is because of the chip itself, but the good quality product has the night vision function, and the image object is not imaged. The effect, although the color will be worse, but it is not a problem.
Waterproof
The same chip, different manufacturers produce products, the waterproof performance is different, so this is also the key that car users need to pay attention to, once the waterproof is not good, it will be waterproof.
5.interface
Currently commonly used interfaces on the market are: RCA, BNC, aviation plugs, and a small number of S terminals, the most professional is the aviation plug (collecting power, ground, signal integration), in anti-shock performance, anti-interference ability, anti-folding Sex, installation structure, are not comparable to other interfaces, so it is also the first product of the car factory.
