Difference between 4-lamp reversing camera and 12-lamp reversing camera

At present, there is little difference between the two, and the level of the camera itself and the chip play a greater role.

Camera lights may be overexposed in recent reversing images when used. When reversing, the reversing image is white and you can't see anything. Some reversing cameras use chip self-fill light technology, and the reversing image seen when reversing at night is very clear.

You can choose the reversing camera from the following directions.

1, 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. It is suggested to choose CCD camera without considering the cost.

Step 2 be clear

Sharpness is one of the important indexes to measure a camera. It is suggested to judge according to the grade of camera chip. Generally, different chip grades and different photosensitive elements, including the level of debugging technicians, may have different effects on the same chip and products of the same grade. On the contrary, the night vision effect of high-definition products will be discounted.

Generally, the number of lines used for reversing cameras is high-definition, such as 420 lines, 480 lines, 500 lines, 580 lines and 600 lines.

3. Night vision

The higher the definition, the worse the night vision effect will be, because the night vision effect is also related to the definition of the product. Generally, products with good quality have night vision function, which will not affect the rendering effect. Night vision is generally called infrared night vision or white led night vision. Without infrared light, it can only be said that low illumination is good, and the imaging effect will be better under the same illumination conditions.

4. Waterproof material

Reversing cameras are generally waterproof, which can better protect the camera and extend the life of reversing cameras.

5, shockproof and dustproof

The reversing camera has shockproof and dustproof functions.

Precautions for reversing camera

1, can't completely rely on the reversing rearview system, but can only be regarded as an auxiliary tool for reversing.

3. The vehicle monitor must be connected correctly. If the monitor does not provide an AV input interface, you must find the corresponding video cable or install a video switching device so that the rear view image can be displayed normally.

[14], do not easily connect the vehicle electrical power supply directly to the vehicle battery power supply, so as not to cause power instability.
