How car cameras work

1. The working principle of the car camera.

The power supply of the camera is connected to the reversing taillight. When the reverse gear is engaged, the camera synchronously supplies power and enters the working state, and sends the collected video information to the wireless receiver placed in the front of the car through the wireless transmitter, and the receiver sends the video information through the AV. The IN interface is transmitted to the GPS navigator, so that when the receiver receives the signal, no matter what kind of operation interface the GPS navigator is in, the LCD screen will be preferentially provided for the reversing image video.

2. Car camera features.

(1) Chip

CCD and CMOS chips are an important part of the reversing camera, which can be divided into CCD and CMOS according to different components. CMOS is mainly used in products with lower image quality. Its advantages are that the manufacturing cost and power consumption are lower than that of CCD. The disadvantage is that CMOS cameras have higher requirements for light sources; A video capture card is included. There is a big gap between CCD and CMOS in technology and performance. Generally speaking, CCD has better effect, but the price is also more expensive. It is recommended to choose CCD camera without considering the cost.​​

(2) Waterproof

The products of the reversing camera basically have the waterproof function to avoid being eroded by the rain and ensure their normal performance.​​

(3) Night Vision

The night vision effect is related to the clarity of the product. The higher the clarity of the product, the less good the night vision effect is. This is because of the chip itself, but good quality products have night vision function, and will not image objects. The effect, although the color will be worse, but the clarity is not a problem.​​

(4) Clarity

Clarity is one of the important indicators to measure the camera. Generally speaking, products with high definition will have better image quality. At present, products with a definition of 420 lines have become the mainstream products of reversing cameras, and those with 380 lines can also be selected if they are well debugged. However, according to the different chip levels of each camera, different photosensitive elements, including the level of debugging technicians, products of the same chip and the same level may show different quality effects. On the contrary, the night vision effects of high-definition products will be displayed. some discounts.​​

In short, when choosing a reversing camera, you can consider the above aspects. The most important thing is to see and compare the actual effect of the image, so that it can better play its performance.
