What kind of car camera is good? You can examine the performance of the car camera from the following aspects:
1. Chip
CCD and CMOS chip is an important part of the astern camera, according to the different components can be divided into CCD and CMOS. CMOS is mainly used in low image quality products, its advantages are lower manufacturing cost, power consumption than CCD, the disadvantage is that CMOS cameras have higher requirements for light sources; CCD is a high-end technical component used in photography and video recording, and also has a video capture card. CCD and CMOS in technology and performance gap is very large, in general, CCD effect is better, but the price is more expensive, it is recommended to choose the CCD camera without considering the cost.
Ii. Clarity
Sharpness is one of the important indicators to measure the camera. In general, the quality of the image of the product with high clarity will be better, the clarity of the product in 420 lines has become the mainstream product of the reversing camera, and the 380 line can also be selected if the debugging is good. There are better chip 480 lines, 600 lines, 700 lines, etc. But according to the chip level of each camera, the sensor is different, including the level of debugging technicians, the same chip of the same level of products may present different quality effects, and to see what kind of lens is used, good materials made of lenses, The image rendering effect will be much better, on the contrary, the high-definition product night vision effect will be discounted.
3. Night vision
Night vision effect is related to the clarity of the product, the higher the clarity of the product night vision effect will not be very good, this is because of the chip itself, but good quality products have night vision function, and will not image the object image effect, although the color will be worse, but clear is not a problem. If there is infrared night vision fill light or LED white light fill light, night vision more clearly visible
Night vision effect is related to the clarity of the product, the higher the clarity of the product night vision effect will not be very good, this is because of the chip itself, but good quality products have night vision function, and will not image the object image effect, although the color will be worse, but clear is not a problem. If there is infrared night vision fill light or LED white light fill light, night vision is more clearly visible
The products of the reverse camera are basically waterproof
To sum up: Choose the reversing camera from the above aspects, the most important thing is to see, to compare the actual effect of the image.
Five, special car reversing camera
Many cars have been produced special car reversing camera can be used with more than 500 models, when choosing must first choose their own car reversing camera, if not, then choose general reversing camera.
Six, universal camera.
The general general camera has 18.5mm perforated camera, small butterfly external camera, license plate frame camera, 28mm perforated camera, bus camera and other external cameras, etc., such as the car navigator LED night vision color external camera working principle:
The camera power supply is connected to the astern taillight. When it is put into reverse gear, the camera synchronously supplies power and enters the working state. The collected video information is sent to the wireless receiver placed IN the front of the car through the wireless transmitter, and the receiver transmits the video information to the GPS navigator through the AV IN interface. No matter the Gps navigator is in any kind of operation interface, the LCD screen will be preferentially provided for reversing video.
The difference between the car camera and the car display and the car DVD navigator portable GPS navigator, when the car display is used, the car display does not need to be turned on as long as the car display hangs the reverse gear, the car display will automatically display the car camera image; And car DVD navigation is generally boot condition to display car camera image; When using a portable GPS navigator, the car camera image can be displayed only when the navigator is turned on
