What is the camera in front of the Audi q5 for?

Audi q5' s front camera is used to monitor the situation under the front bumper of the car, mostly to eliminate dead ends.

The front camera enters the parking space and can't see under the bumper, and the eyes can't see everything in front. If you have a forward-looking camera, you can sweep away the dead angle. Especially for large-scale modified vehicles or off-road vehicles, it is necessary to install forward-looking cameras, which can reduce many minor accidents.

There are two kinds of reversing cameras: wired and wireless. Wired mode is simple and reliable, but it needs wiring in the car. The wireless mode does not need wiring in the car body, and the installation is simple, but it needs to add a wireless receiving module. Because the receiving effect of the wireless receiving module is not ideal, the general reversing camera still adopts wired mode.

You can examine the performance of the camera from the following aspects:

chip

CCD and CMOS chips are important components of reversing camera, which can be divided into CCD and CMOS according to the different components. CMOS is mainly used in products with low image quality. Its advantage is that the manufacturing cost and power consumption are lower than CCD, but the disadvantage is that CMOS cameras require higher light sources. CCD is a high-end technology component for photography and video shooting, with video capture card.

There is a big gap between CCD and CMOS in technology and performance. Generally speaking, CCD works better, but it is also more expensive.

Clarity/clarity

Sharpness is one of the important indexes to measure a camera. Generally speaking, products with high definition will have better picture quality. 420-line resolution products have become the mainstream products of reversing cameras, and 380-line resolution products can also be selected if debugged well.

However, depending on the chip grade of each camera, the photosensitive elements are different, including the level of debugging technicians, the products of the same chip and grade may show different quality effects. On the contrary, the night vision effect of high-definition products will be discounted.

night vision

The night vision effect is related to the clarity of the product. The higher the definition, the worse the night vision effect will be. This is because of the chip itself, but the products with good quality have night vision function, which will not affect the imaging effect of the object. Although the color will be worse, the clarity is not a problem. The night vision effect will be more clearly visible at night with infrared or white LED lights.
